G6PD Test

What is a G6PD Test?

A Glucose-6-phosphate dehydrogenase (G6PD) test is a laboratory test that is used to measure the activity of the enzyme named glucose-6-phosphate dehydrogenase (G6PD) in red blood cells. The G6PD enzyme plays an important role in producing ATP, a chemical that provides energy for the cells. A G6PD test is usually ordered when a person has certain types of anemia or other medical conditions, or if the person is taking certain medications.

Preparation for G6PD Test

No special preparation is required for a G6PD test. You may be asked to fast for a period of time before the test, but this is not always necessary.

Procedure for G6PD Test

A blood sample is taken from the patient and sent to the laboratory for analysis. The sample is analyzed to measure the activity of the G6PD enzyme in the red blood cells. The results of the test are usually available within a few days.

Types of G6PD Test

There are two types of G6PD test: a colorimetric test and a spectrophotometric test. The colorimetric test measures the amount of G6PD enzyme directly in the blood sample, while the spectrophotometric test measures the amount of G6PD-related substances. Both types of tests can provide accurate results.

Risks of G6PD Test

A G6PD test is a safe procedure. The only risk associated with the test is the small risk of infection caused by the needle used to draw the blood sample.

When G6PD Test Recommended?

A G6PD test is usually ordered when a person is suspected of having certain types of anemia or other medical conditions, or when they are taking certain medications. It is also used to diagnose a G6PD deficiency.

Why G6PD Test Required?

A G6PD test is performed to measure the activity of the G6PD enzyme in the red blood cells. It is used to help diagnose certain types of anemia or other medical conditions, or to determine if a person is taking certain medications that may affect the G6PD enzyme in the red blood cells.
