MSRA-0690
A 50-year-old man visits his doctor with concerns about his recent private medical screening test results. His liver function tests have shown abnormalities, but he has no symptoms and is generally healthy. He admits to consuming approximately 40 units of alcohol per week. The following are his blood test results:
– Bilirubin: 21 µmol/l
– ALP: 100 u/l
– ALT: 67 u/l
– γGT: 110 u/l
– Albumin: 40 g/l
Other blood tests, including FBC, U&Es, and fasting glucose, were normal. An ultrasound of his liver revealed fatty changes. His liver screen showed:
– Hepatitis B: Negative
– Hepatitis C: Negative
– Serum ferritin: 550 microg/L (normal range: 25-300 microg/L)
– Immunoglobulins: Normal
– Transferrin saturation: 41% (normal range: <50%)
What is the most likely underlying cause of the elevated ferritin levels?
