G6PD (Glucose 6-Phosphate Dehydrogenase), Quantitative, Blood and Red Blood Cell Count (RBC)

What is a G6PD test?

G6PD (Glucose 6-Phosphate Dehydrogenase) is a type of blood test that is recommended to find out the levels of glucose-6-phosphate dehydrogenase (G6PD) in the blood. It is an enzyme that is found in the blood and it is responsible for cell function.

G6PD can be termed as a safeguard for red blood cells (RBC), protecting them against all types of damaging side-effects that can possibly damage the cells at the moment when your body is fighting against infections. The side-effects may also be a result of some certain medications.

When the G6PD level is low:

G6PD protects the red blood cells (RBCs) against many elements and side-effects, also known as Reactive Oxygen Species (ROS). The level of G6PD may come down in your body during the following health conditions:

  • Fever or infection
  • Under certain medications
  • Due to certain foods that can be infectious

In case of the low level of G6PD in your blood, the red blood cells would easily get affected from infections and other chemical elements, and the cells start dying if appropriate action is not taken on time.

When the G6PD test is recommended:

If you are experencing some of these common symptoms, consider the G6PD test. If you experience any of the following health conditions, G6PD test is necessary to measure the level of glucose-6-phosphate dehydrogenase (G6PD) in your blood:

  • Rapid heart rate
  • Dark urine
  • Shortness of breath
  • Yellowing skin and eyes
  • Fatigue

What is tested?

G6PD deficiency may lead to anemia and other serious health conditions. To find out an accurate report, your doctor would require the tests like Glucose 6-Phosphate Dehydrogenase (G6PD), Quantitative, Blood and Red Blood Cell Count (RBC) - TC – 500.

How to prepare for a G6PD test?  

Usually, no preparation is necessary for the test. However, you must tell your doctor if you are under any medication. Some certain conditions don’t allow for the test. Let the doctor know if you have taken any of the following things:

  • Antibacterial or antifungal drugs
  • Diuretics, or water pills
  • Anticonvulsants

These medications can potentially leave undesirable reactions if you undergo the G6PD test.
