Final answer:
The patient shows signs of hemochromatosis with elevated serum iron and ferritin levels, and low-normal transferrin. These abnormal lab values and the family history suggest a likely diagnosis of hemochromatosis, for which genetic testing can provide confirmation.
Step-by-step explanation:
The patient's lab results suggest a potential diagnosis of hemochromatosis. This hereditary disease is characterized by an accumulation of iron in the body, potentially leading to liver damage. To evaluate the patient, we consider serum iron levels, transferrin saturation, and serum ferritin levels.
Firstly, the serum iron concentration is elevated at 200 µg/dL, exceeding the normal range for males of 65 to 176 µg/dL. This indicates an abnormality in serum iron concentration. Secondly, the transferrin level, which is a protein that binds iron in the blood and controls iron absorption, is low at 210 mg/dL when compared to the normal range of 215 to 380 mg/dL. While this value is on the lower end of normal, it is not significantly low. However, the serum ferritin level, which reflects the body's iron stores, is elevated at 350 ng/mL, exceeding the upper limit of the normal range (12-300 ng/mL). Elevated ferritin is often a marker of increased iron stores as seen in hemochromatosis.
In summary, the combination of elevated serum iron, low-normal transferrin, and increased ferritin suggests that this patient may indeed have hemochromatosis, especially considering their familial history. Genetic testing for hereditary hemochromatosis should be considered to confirm the diagnosis and guide further management.
