G6PD Test
G6PD Test
Glucose-6-phosphate dehydrogenase (G6PD) test is a blood test used to determine whether a person has a deficiency in G6PD enzyme activity. G6PD deficiency is an inherited condition in which the body doesn't produce enough of the G6PD enzyme. This condition can interfere with the body's ability to produce red blood cells.
Preparation for the Test
No fasting or special preparation may be necessary for the G6PD test.
Procedure for the Test
The G6PD test is performed by taking a sample of blood from a vein in your arm. The sample is then sent to a laboratory for analysis.
Types of G6PD Test Available
- Complete blood count (CBC) – This test measures the number of red and white blood cells and platelets circulating in the bloodstream.
- Functional G6PD test – This test measures the amount of G6PD present in the sample of blood taken.
- Molecular G6PD test – This test looks for genetic mutations in the G6PD gene.
Risks of G6PD Test
The risks associated with G6PD test are minimal. There is a small risk of bleeding and infection from the draw site. There is also a very small risk of an allergic reaction to the anticoagulant used to collect the sample.
Why is G6PD Test Performed?
G6PD test is used to diagnose G6PD deficiency. It is also used to monitor the effects of drugs on the body, and to determine if a person is sensitive to certain medications. Symptoms of G6PD deficiency include severe anemia, jaundice, seizures, and enlargement of the spleen and liver.
When is G6PD Test Performed?
G6PD test is typically performed if a person has family history of G6PD deficiency or is experiencing symptoms associated with G6PD deficiency. The test is also performed when a person has been exposed to certain medications, such as antimalarial drugs.
