What blood tests are used to diagnose hemochromatosis?

Diagnosing hemochromatosis typically involves several blood tests that assess iron levels and the body’s ability to store and process iron. These tests help determine whether there is an excess of iron in the body and can point toward a diagnosis of hemochromatosis. Here are the key blood tests used:

1. Serum Ferritin Test

  • Purpose: Measures the amount of ferritin, a protein that stores iron in the body.
  • Interpretation:
    • Elevated levels of ferritin indicate excess iron storage, which is a hallmark of hemochromatosis.
    • However, high ferritin levels can also be caused by other conditions like inflammation or infection, so further testing is required to confirm hemochromatosis.

2. Serum Iron Test

  • Purpose: Measures the amount of iron in the blood.
  • Interpretation:
    • High serum iron levels may indicate that the body is absorbing too much iron, consistent with hemochromatosis.

3. Total Iron Binding Capacity (TIBC) Test

  • Purpose: Measures the blood’s capacity to bind iron with transferrin (a protein that transports iron in the blood).
  • Interpretation:
    • Low TIBC levels suggest that the body has excess iron, as there is less available transferrin to bind with more iron.

4. Transferrin Saturation (TS) Test

  • Purpose: Measures the percentage of transferrin that is bound with iron. It is calculated using the serum iron and TIBC values.
  • Interpretation:
    • Normal Range: Typically between 20% and 50%.
    • High Transferrin Saturation: Levels above 45% can indicate hemochromatosis, especially if other iron measures are elevated. In severe cases, this percentage may exceed 60-70%.

5. Genetic Testing (HFE Gene Test)

  • Purpose: Detects mutations in the HFE gene, which are responsible for hereditary hemochromatosis. The two most common mutations are:
    • C282Y: The most common mutation associated with hemochromatosis.
    • H63D: A less common mutation, which can lead to hemochromatosis when combined with the C282Y mutation (compound heterozygosity).
  • Interpretation:
    • Positive for C282Y/C282Y: Most common genetic profile for hereditary hemochromatosis.
    • C282Y/H63D Compound Heterozygote: Some individuals with this combination may develop hemochromatosis.
    • H63D/H63D or single mutation: May not cause significant iron overload on its own but could still contribute in combination with other factors.

6. Liver Function Tests

  • Purpose: These tests check for elevated liver enzymes (e.g., ALT, AST), which can indicate liver damage caused by iron buildup.
  • Interpretation:
    • Abnormal liver enzyme levels suggest that iron overload is affecting the liver, potentially leading to conditions like cirrhosis.

7. Liver Biopsy (in Advanced Cases)

  • Purpose: A liver biopsy may be performed if there is suspicion of significant liver damage (such as cirrhosis) or to confirm iron overload in the liver tissue.
  • Interpretation:
    • A liver biopsy can show the extent of iron deposition and damage, including fibrosis or cirrhosis.

8. MRI (Magnetic Resonance Imaging)

  • Purpose: MRI can be used to non-invasively assess iron levels in organs, particularly the liver and heart.
  • Interpretation:
    • An MRI can detect iron overload in the liver and other organs, helping to evaluate the severity of iron deposition and organ damage.

9. Complete Blood Count (CBC)

  • Purpose: A CBC is a standard blood test that assesses overall health by measuring different blood components.
  • Interpretation:
    • While it is not specific to diagnosing hemochromatosis, a CBC may be used to rule out other conditions, such as anemia, that could be causing symptoms.

Conclusion

The primary blood tests for diagnosing hemochromatosis are the serum ferritin, serum iron, total iron binding capacity (TIBC), and transferrin saturation tests. If these indicate iron overload, genetic testing for mutations in the HFE gene can confirm a diagnosis of hereditary hemochromatosis. In more advanced cases, liver function tests, liver biopsies, or MRI may be used to assess the extent of organ damage. Early diagnosis and treatment are key to preventing complications associated with iron overload.
