The Essential Tests for Diagnosing Hemochromatosis
Getting Diagnosed
Diagnosing hereditary hemochromatosis involves a series of tests to assess iron levels and genetic markers. Discover the key tests and what they reveal.

Blood Tests: The First Step
Blood tests are crucial in diagnosing HH, measuring serum ferritin and transferrin saturation (TSAT) to assess iron levels. High levels may indicate iron overload, prompting further investigation. Regular monitoring of these tests helps catch changes early.
Genetic Testing for Confirmation
Genetic testing identifies mutations in the HFE gene, confirming a diagnosis of HH. The most common mutations are C282Y and H63D. This test is particularly important for family members of those diagnosed with HH.
Imaging and Biopsy
For a detailed assessment, MRI or liver biopsy may be used to evaluate organ iron deposition. These tests help determine the extent of iron accumulation and guide treatment decisions. Biopsies are more invasive and are typically reserved for complex cases.

Is a biopsy always needed?
No, it's reserved for complex cases.
What do blood tests measure?
They measure serum ferritin and TSAT levels.
Wrapping Up
