Patient Script
For the friend playing the patient role
Character Overview: You are Niall Sweeney, a 52 year old general manager of a members' golf club in a Warwickshire village. You took the job three years ago after years running events at a hotel in Coventry. You are taking this call in your clubhouse office before a society golf day. You are friendly, chatty and practical, and you use humour to steer away from anything awkward, especially your drinking.
Three weeks ago you had a health check through the club's new private scheme for senior staff. You felt fine; it was a perk. The report said your ferritin was high and to see your GP. You read online that iron overload runs in families, is common in people with Irish roots, can damage the liver and heart, and is treated by having blood taken off. Both parents came from County Donegal, so you decided this is what you have, and you booked a slot at the village hall blood donation session a week on Thursday. You have never given blood before. You only say "iron overload" or "too much iron" and never name a particular condition.
Much of your job happens at the bar: members like to buy the manager a drink and you sit with the committee after work. You do not think of yourself as a big drinker. You have put on about two stone since you started, eating from the clubhouse kitchen and hardly playing golf. Your wife Siân has been on at you about both. Deep down you would rather this was your genes than your drinking, because that would not be your fault. You do not volunteer how much you drink, or that you would prefer it to be the iron, unless asked.
Opening Sentence: "Hiya, thanks for ringing me back. So my health check through work came back saying my ferritin's high, which I gather is iron. I've done a bit of reading, and I think the sensible thing is I just start giving blood. Two birds with one stone, isn't it? I just wanted to run it past you first."
History if Asked (Data Gathering Phase)
- ●Why he had the bloods: "It was a perk from the club's private scheme. I wasn't ill, I just went along."
- ●How he feels: "Fine, honestly. A bit flat in the afternoons, but I'm up at six and some nights I'm here till ten. Anybody would be."
- ●What the report said: "Just that the ferritin was high and to see my GP. A couple of the liver ones had little stars next to them, but it didn't say anything about those." Never had these checked before.
- ●Recent illness (if asked about infections or being unwell around the test): "Now you mention it, I had an abscess on a back tooth about a fortnight before. The dentist drained it and gave me five days of antibiotics, amoxicillin I think. It settled in a couple of days."
- ●Alcohol (first answer): Light and deflecting. "I'm a social drinker. In this job you can't really avoid it, it comes with the territory."
- ●Alcohol (if the doctor asks for detail): "Monday to Thursday a couple of pints of lager in the clubhouse after work, about four percent. Friday and Saturday Siân and I share a bottle of red with dinner, so half each. And a pint with Sunday lunch."
- ●How long (if asked): "A lot less before this job, a few pints at the weekend. It's crept up these last three years. It feels rude to say no."
- ●Dependence (if asked about morning drinking, shakes, cravings or trying to stop): "No, never first thing. No shakes or anything. I gave up for Lent two years ago, no bother at all. I just enjoy it."
- ●Weight (if asked): "About two stone on since I started. I used to play three or four rounds a week, now I'm lucky to get out once a fortnight. And there's always chips coming out of the kitchen."
- ●Activity (if asked): "On my feet all day, but no proper exercise. I walk the dog at weekends."
Ideas, Concerns, Expectations
Gating note: Niall does not raise any of the following himself. Each part comes out only when the doctor asks what he thinks is going on, what is worrying him, or what he was hoping for.
- ●Ideas: He thinks he has inherited iron overload. "I read it runs in families and it's common in people with Irish roots. Mum and Dad were both from Donegal, so it added up. And the treatment is having blood taken off, isn't it? So why not give it to someone who needs it."
- ●Concerns: "One article said it can wreck your liver and heart." If the doctor explores further, or links his drinking or weight to the result, he goes quieter: "I'll be honest, I'd almost rather it was the iron. At least that's in my genes, not something I've done. Siân's been on at me about the drinking for a while. And the drinking's half the job."
- ●Expectations: "I've booked a slot at the blood session in the village hall a week on Thursday. I was hoping you'd say crack on. And maybe give me a note so I can go more often than normal."
If Asked: Medical History and Medications
Gating note: Niall answers each of these plainly when the doctor asks about it.
- ●Past health: "Just my knee, keyhole surgery in 2019."
- ●Medicines, transfusions and allergies: "Nothing regular. Ibuprofen once a month if the knee plays up. No vitamins or iron tablets. Never had a transfusion. No allergies."
- ●Family history: "Dad died at 71 of a stroke. Mum's 78 and has diabetes, the tablet sort. My sister Bridget is 48 and fine. Nobody's had iron trouble or liver problems that I know of. Mum and Dad came over from County Donegal in the seventies; I was born in Coventry."
- ●Hepatitis risks (if asked): "One tattoo on my shoulder, done in Coventry when I was nineteen. Never injected anything."
Social History and Lifestyle Impact
Gating note: Niall shares this naturally when asked about his work, home or routine.
- ●Work: Long days in the season: early starts for tee times, committee meetings and functions in the evenings.
- ●Home: Lives with Siân, who works at the county library, ten minutes' walk from the club. No children. A springer spaniel called Murphy. He walks home from work.
- ●Smoking and diet: "Gave up smoking at thirty. Breakfast on the go, lunch from the clubhouse kitchen, usually with chips. Siân cooks proper food at night."
If Asked: Associated Symptoms
Gating note: Niall answers briefly and only when asked. The following are all negative: pain or stiffness in the hands or knuckles ("My grip's fine, I'd notice on the golf course"), other joint pain apart from the odd twinge in the right knee, loss of sex drive, skin colour change beyond a golfer's tan, thirst, yellow skin or eyes, itching, dark urine, tummy pain, vomiting blood or black stools, weight loss, sweats or fevers, breathlessness, chest pain or palpitations, and low mood or poor sleep.
- ●If asked about his tummy: "The belly's bigger, but that's the chips."
Responses to Management (The Negotiation Phase)
- ●If the doctor says drink, weight or a strained liver can raise ferritin, or works out his units:
- ●Reaction: Defensive humour. "Ah, here we go. I knew the drink would come up. I'm hardly propping up the bar every night." If the doctor stays matter of fact he softens: "I suppose a couple of pints most nights is propping it up a bit." Told it is about 30 units a week: "Thirty? It doesn't feel like thirty. What am I supposed to be on, then?"
- ●If the doctor says he should not give blood next week:
- ●Reaction: Disappointed. "But that's the treatment, isn't it? I'd be sorting myself out and helping someone else. Where's the harm?" Once told the blood service does not take donors waiting for results, and that it would not fix a ferritin raised by drink or weight: "Fair enough. So it'd be like bailing the water out without fixing the leak. Do I cancel? Can I rebook later?" Pleased if he may give blood later.
- ●If the doctor explains the next blood test and mentions a gene test:
- ●Reaction: "So the first test didn't tell you the whole story?" About the gene test: "Can't we just do that now? I'd rather know." Told it follows only if the iron test is raised: "Right. And if it does come back high, what happens then? How often, and for how long? I've got the club championship in the spring."
- ●Once the tests have been explained, whatever plan is proposed:
- ●Reaction: Direct. "So, straight answer, Doctor. Is it the iron thing or not?" Once a plan is agreed: "If it is the drink and the weight, will the numbers come back down? Or is the damage done?"
- ●If the doctor advises 14 units a week, or asks what he could change:
- ●Reaction: "Fourteen a week? That's two nights in the clubhouse. There's always someone wanting to buy the manager a pint." Asked what he could change: "I suppose I could have the alcohol free lager on weekdays. Nobody would know what's in my glass. And keep the wine for Saturday." About weeks off before the repeat tests: "I did Lent, I can do that. Would it change the numbers?" About weight: "I know, I know. What's realistic, though? I'm not joining a gym."
- ●If the doctor suggests liver tests or a scan, arranges a visit, or gives safety netting:
- ●Reaction: Slightly anxious. "Is my liver damaged, then? Should I be worried?" If referred to hospital straight away: "Is it that serious? I thought you'd do the tests first." He can come in for bloods before eight, before the golfers arrive. Vague safety netting such as "ring if you're worried": "Worried about what, though? I feel fine." Specific warning signs: "Yellow eyes, black stools, right, got it. And when will you have the results?"

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Niall has a ferritin of 820 micrograms/L from a work health check, drinks about 30 units a week, has gained 13 kg in three years, and has decided he has inherited iron overload that he can treat by giving blood.
- ●The task is to interpret the ferritin properly, request the test that separates iron overload from other causes, address alcohol and weight, and steer him away from donating without making him feel foolish.
- ●Model answer: repeat ferritin with transferrin saturation (plus CRP and full blood count), a liver screen for the raised ALT and GGT, brief alcohol advice towards 14 units or less, weight advice, no blood donation while tests are pending, HFE genotyping only if the transferrin saturation is raised, and a defined follow up.
- ●Also acceptable: a period without alcohol instead of an immediate 14 unit target; a fasting or morning sample; HFE genotyping alongside the transferrin saturation; advising him to declare the pending tests at the donor health check; any defined interval for repeat tests.
What Ferritin Does and Does Not Measure
- ●Ferritin stores iron, so a low value reliably indicates deficiency, but a high value is far less specific. It is also an acute phase protein released from damaged liver cells, and it rises with alcohol, fatty liver, infection, inflammation, kidney disease and malignancy as well as true iron overload (British Society for Haematology (BSH) raised ferritin guideline, 2018).
- ●Most people with a raised ferritin do not have haemochromatosis. The British Society of Gastroenterology (BSG) and British Association for the Study of the Liver (BASL) 2018 guideline on abnormal liver blood tests states that an isolated raised ferritin is commonly seen with alcohol excess and fatty liver disease and does not reflect haemochromatosis.
- ●A ferritin above 1000 micrograms/L makes iron overload more likely and is a trigger for going straight to haemochromatosis screening and hepatology referral (BSH 2018). Below 1000, severe iron related liver scarring is unlikely (European Association for the Study of the Liver (EASL) 2022).
Reading Niall's Results as a Whole
- ●GGT 88 U/L, ALT 58 U/L and MCV 101 fL together point towards alcohol and a liver under strain. Raised GGT and macrocytosis are classic markers of regular drinking. An AST to ALT ratio below 1 (41 to 58) is more typical of fat related liver change, but neither pattern is diagnostic.
- ●A BMI of 31.5 with a 13 kg gain since 2019 adds a metabolic contribution. The dental abscess two weeks before the test may have nudged the ferritin up, which is one reason to repeat it. The screen did not include transferrin saturation or CRP, so the iron picture is incomplete.
Transferrin Saturation and the Gene Test
- ●Transferrin saturation shows how much iron is carried in the blood and is the first biochemical abnormality in haemochromatosis. It separates true iron loading from a ferritin raised for other reasons. A non fasting sample is acceptable (BSH 2018), though a morning sample is advised by EASL 2022. A raised value is above 50% in men.
- ●A normal transferrin saturation with a ferritin below 1000 makes haemochromatosis very unlikely. BSH 2018 then recommends observation with lifestyle change and repeat assessment after 3 to 6 months.
- ●HFE haemochromatosis is autosomal recessive, and 80% to 90% of cases in people of northern European ancestry are C282Y homozygotes. BSH 2018 recommends genotyping for a ferritin above 300 with a transferrin saturation above 50% in men, and EASL 2022 requires informed consent. Testing the gene first is not recommended, because homozygosity is common (about 1 in 83 in Ireland, EASL 2022) and penetrance low.
- ●BSH 2018 notes that with a ferritin above 1000 or abnormal liver tests, proceeding directly to screening is reasonable, so genotyping alongside the transferrin saturation is defensible in Niall's case.
Alcohol: Quantify, Feed Back, Agree a Goal
- ●Units are volume in mL multiplied by percentage strength, divided by 1000. Niall drinks eight pints of 4% lager from Monday to Thursday (about 18 units), a pint on Sunday (2.3 units) and half a bottle of 13.5% wine on Friday and Saturday (about 10 units): about 30 units a week.
- ●The low risk guideline is no more than 14 units a week, spread over three or more days. Over 14 and under 50 units in a man is increasing risk drinking (NICE Clinical Knowledge Summaries (CKS), alcohol problem drinking). An AUDIT C score of 5 or more prompts the full AUDIT.
- ●Structured brief advice follows FRAMES: feedback, responsibility, advice, a menu of options, empathy and self efficacy, for example alcohol free drinks, drink free days or a diary.
- ●Ask about morning drinking, withdrawal and failed attempts to stop before advising a big cut. Dependent drinkers should not stop suddenly without support, and NICE PH24 says not to offer simple brief advice to anyone who may be dependent. Niall has no features of dependence.
Weight, Fatty Liver and Assessing the Liver
- ●Metabolic dysfunction associated steatotic liver disease is diagnosed only when men drink less than 30 g a day. At about 240 g a week Niall falls into the metabolic and alcohol related category (MetALD) under the 2023 nomenclature, so both alcohol and weight need addressing.
- ●Raised liver enzymes deserve a liver screen in their own right: BSG and BASL 2018 lists abdominal ultrasound, hepatitis B surface antigen, hepatitis C antibody, autoantibodies and immunoglobulins.
- ●His FIB4 score is (52 × 41) ÷ (236 × √58), about 1.2, below the 1.3 low risk threshold (BSG and BASL 2018). It is validated in metabolic rather than alcohol related disease, so it supports rather than settles the assessment; an ELF test or elastography can follow through the local pathway.
- ●CKS advises gradual weight loss of 5% to 10% over six months, a deficit of about 600 kcal a day, and 150 to 200 minutes of moderate activity a week.
Why Giving Blood Is Not the Answer Now
- ●UK blood services do not accept donors who are waiting for investigations or results for an undiagnosed condition (Joint United Kingdom Blood Transfusion and Tissue Transplantation Services Professional Advisory Committee (JPAC) donor selection guidelines). Niall would be deferred at the donor health check.
- ●Removing blood is not a treatment for ferritin raised by alcohol or fatty liver, and neither BSH 2018 nor EASL 2022 finds evidence that it helps. A donation before the repeat tests can also temporarily lower the transferrin saturation and mask iron overload (BSH 2018).
- ●Donation intervals and approval for anyone with haemochromatosis belong to the blood service, not a GP's note. His wish to give blood is a good one and he can rebook once the results are clear.
If Haemochromatosis Is Confirmed
- ●C282Y homozygotes are referred to a specialist. BSH 2018 recommends hepatology assessment, at minimum with elastography, for a ferritin above 1000 or abnormal liver tests, so with his raised ALT and GGT Niall would go to hepatology.
- ●Venesection removes 450 to 500 mL of blood, usually weekly at first until the ferritin is low (BSH 2018 aims for 20 to 30 micrograms/L, EASL 2022 for below 50), then a few times a year. Many homozygotes never develop organ damage (iron related disease in 28% of men over 12 years, EASL 2022). Alcohol must stay low, because alcohol and iron together damage the liver more than either alone.
- ●If he were homozygous, his first degree relatives, here his sister Bridget, would be offered ferritin, transferrin saturation and HFE testing.
Follow Up, Referral and Safety Netting
- ●Agree how he will hear the transferrin saturation and liver screen results, typically within one to two weeks, and who acts on them. Agree a time to repeat the ferritin and liver tests after cutting down; BSH 2018 suggests 3 to 6 months when transferrin saturation is normal, and stopping alcohol usually lowers ferritin within weeks to months.
- ●Refer if the transferrin saturation is raised and he is a C282Y homozygote, if the ferritin is above 1000 or rising, if it stays raised and unexplained despite addressing alcohol and weight, or if the liver screen or fibrosis testing suggests significant liver disease.
- ●Advise same day contact for yellow eyes or skin, vomiting blood or black stools, a swelling tummy or new confusion. "Ring if you're worried" is not enough for a man who feels well.
Common Mistakes in This Station
- ●Endorsing blood donation, or writing a note supporting more frequent donation.
- ●Diagnosing or excluding haemochromatosis from the ferritin alone, or ordering the gene test without a transferrin saturation.
- ●Accepting "social drinker" without working out the weekly units, and so missing the most likely cause.
- ●Focusing only on iron and ignoring the raised ALT, GGT and MCV.
- ●Referring straight to hospital before the simple primary care tests, which alarms him and delays the answer.
- ●Lecturing about alcohol so that he becomes defensive, rather than building a plan that fits his job.
- ●Safety netting with "ring if you're worried".
