About Our Glucose 6-Phosphate Dehydrogenase (G6PD) Test, Quantitative

The G6PD blood test determines whether you have a glucose-6-phosphate dehydrogenase (G6PD) deficiency, a genetic condition that affects how red blood cells protect themselves from damage. G6PD is an essential enzyme that helps red blood cells function normally and survive everyday oxidative stress.

When G6PD levels are low, red blood cells can break down prematurely, a process known as hemolysis, when exposed to certain medications, foods, infections, or environmental triggers. Because symptoms often do not appear until exposure occurs, testing is the most reliable way to identify this condition before serious complications develop.

What Is Included In This Test?

This test measures the level of G6PD enzyme activity in your blood to assess how well your red blood cells can withstand oxidative stress.

Your results can help:

Identify G6PD deficiency
Assess risk for hemolytic anemia
Guide safe medication and treatment choices
Prevent red blood cell breakdown triggered by specific substances
Support proactive health and lifestyle planning

Knowing your G6PD status can help you avoid common triggers such as certain medications, infections, and foods that may cause dangerous red blood cell destruction.

Who Should Consider This Test?

This test is ideal for individuals who may be at risk for G6PD deficiency or want to prevent adverse reactions before they occur.

You should consider this test if you:

Have a family history of G6PD deficiency
Are planning to take medications known to trigger hemolysis
Experience unexplained anemia or fatigue after illness or medication use
Want to identify risks before exposure to certain drugs or foods
Are seeking early detection of a hereditary red blood cell disorder

Early awareness allows for safer medical decisions and reduced risk of preventable complications.

Common Questions:

Why is this test important?

Many people with G6PD deficiency have no symptoms until exposure occurs, testing helps identify risk before complications develop.

Is G6PD deficiency common?

Yes, it is the most common enzyme deficiency worldwide and affects millions of people globally.

How is the G6PD test related to diabetes?

The G6PD test does not diagnose diabetes, but it is important for people with diabetes because G6PD deficiency can affect medication safety and the accuracy of certain diabetes tests. Increased red blood cell breakdown in G6PD deficiency may falsely lower HbA1C results, and some medications used to treat infections or complications in diabetes can trigger hemolysis. Knowing G6PD status helps ensure safer treatment decisions and more accurate blood sugar monitoring.

Do I need to fast before this test?

Fasting is not required for this panel. You can eat and drink normally unless your doctor has given you other instructions.
