What is Glucose-6-Phosphate Dehydrogenase (G6PD)?
Glucose-6-Phosphate Dehydrogenase (G6PD) is a metabolic blood test used to measure glucose levels or long-term blood sugar control. It helps diabetologists diagnose diabetes, identify pre-diabetes, and monitor how well a patient is managing their blood sugar through diet, medication, or insulin.
What does Glucose-6-Phosphate Dehydrogenase (G6PD) measure?
The G6PD test measures the activity of the enzyme glucose-6-phosphate dehydrogenase in red blood cells. This enzyme helps keep red cells protected from oxidative damage. When G6PD is low, red cells can break down more easily. The test quantifies a specific biological marker using techniques such as immunoassay, colorimetric analysis, or microscopy. Results are reported with the measured value, unit, and reference range, allowing your doctor to interpret findings in the context of your health profile.
What do the results of Glucose-6-Phosphate Dehydrogenase (G6PD) mean?
Your doctor will interpret the result in the context of your overall health picture. A mildly abnormal value may just need a repeat test in a few weeks to confirm whether it is a temporary fluctuation or a persistent finding. Significantly abnormal values may trigger further investigation, medication, or referral to a specialist.
