G6PD Test
What is a G6PD Test?
This test determines the level of G6PD present in the blood. G6PD is glucose-6-phosphate dehydrogenase, an enzyme that aids in the functioning of red blood cells.
Red blood cells transport oxygen from the lungs to all the body's cells.
This is a hereditary condition that primarily affects men. Red blood cells can be destroyed if G6PD is deficient. Hemolytic anemia occurs when the red blood cells are destroyed quicker than the body can replenish them. When you have hemolytic anemia, your cells do not obtain enough oxygen.
Most persons with G6PD deficiency are asymptomatic, until they are exposed to particular "triggers" that cause red blood cell death.
What is it used for?
A G6PD test is mainly used to check for a G6PD deficiency.
What is the need a G6PD test?
One might need a G6PD test if they have symptoms of hemolytic anemia. These include:
If your newborn baby's jaundice does not resolve in two weeks he or she may require a G6PD test. If you have a family history of G6PD deficiency, your infant may be tested as well.
What happens during a G6PD test?
A tiny needle will be inserted by a healthcare professional to draw blood from the veins of your arm. Following the insertion of the needle, a small quantity of blood will be collected in a test tube. When the needle goes in, you may feel a slight sting. This normally takes five minutes.
A healthcare practitioner will wipe your baby's heel with alcohol and puncture the heel with a small needle. The provider will take a few drops of blood and apply a bandage to the wound.
How to prepare for this test?
A G6PD test does not require any extra preparation.
Understanding results
If your findings suggest that you have less G6PD than usual, you have a G6PD deficit. But, depending on your health history and exposure to triggers, your symptoms and risk of hemolytic anemia may differ.
Women with slightly lower-than-normal G6PD levels may be "carriers" of a G6PD deficit. It suggests they have one normal G6PD gene and one faulty G6PD gene. These women seldom have symptoms because their normal G6PD genes produce enough healthy red blood cells. But, they run the danger of passing on the faulty gene to their children. Male children are more prone than female children to acquire G6PD symptoms.
Important information to know about G6PD testing?
By avoiding triggering chemicals, most persons with G6PD deficiency may control their illness and prevent symptoms. Your doctor can advise you on which substances you should avoid.
