Product description

This is a G6PD blood test. It will tell you if your body has deficiency of the enzyme G6PD (glucose-6-phosphate dehydrogenase).

What is G6PD deficiency?

G6PD deficiency is an inherited condition. It is when the body doesn’t have enough of an enzyme called G6PD (glucose-6-phosphate dehydrogenase). This enzyme helps red blood cells work correctly. A lack of this enzyme can cause haemolytic anaemia. This is when the red blood cells break down faster than they are made.

What causes G6PD deficiency?

G6PD deficiency is inherited. This means it is passed down from parents through their genes.

Women who carry one copy of the gene can pass G6PD deficiency to their children.

  • Men who get the gene have G6PD deficiency.
  • Women who get the gene are carriers. They often don’t have symptoms. But they can pass the gene onto their children.

Who is at risk for G6PD deficiency?

G6PD deficiency occurs most often in men. It is rare in women.

The disorder affects about 10 to 14 out of 100 African-American men in the U.S. It is also common in people from the Mediterranean area, Africa, or Asia.

The severity of the disorder varies, depending on the group. In African Americans, the problem is mild. It mainly affects older red blood cells. In whites, the disorder is often more serious.
