About the test

This test measures the level of G6PD enzyme, helping to identify G6PD deficiency, the most common enzyme deficiency worldwide. It's particularly prevalent among individuals of African, Mediterranean, and Asian descent. G6PD deficiency, an X-linked genetic disorder, varies in severity and primarily affects males. Newborns may experience prolonged jaundice, while adults could face acute hemolytic anemia with symptoms like jaundice, fatigue, and dark urine. Certain illnesses, foods (like fava beans), and medications can trigger these episodes.

Who might consider it:

This test is crucial for individuals showing symptoms of G6PD deficiency or those with a family history. It's also important for pregnant women with the deficiency, as it can affect pregnancy outcomes.

Symptoms of G6PD Deficiency:

  • Jaundice
  • Fatigue
  • Splenomegaly (enlarged spleen)
  • Dark urine
