Introduction

The Glucose-6-phosphate Dehydrogenase (G6PD) Test measures the activity of the G6PD enzyme in red blood cells. Moreover, G6PD plays a crucial role in protecting red blood cells from oxidative damage. In addition, this test helps diagnose G6PD deficiency, a genetic disorder affecting enzyme production. Furthermore, G6PD deficiency can lead to hemolytic anemia, especially after exposure to certain medications, infections, or foods. Above all, the test identifies individuals at risk of red blood cell destruction, enabling preventive measures. Likewise, healthcare providers use the G6PD Test to monitor patients with suspected hemolytic disorders, ensuring proper management. Consequently, early detection of G6PD deficiency prevents severe complications, improving patient outcomes. Lastly, the test is simple and minimally invasive, making it suitable for routine screening and diagnostic purposes.

Test Result, Unit, Reference Range, and Test Methods

The G6PD Test measures the activity of the G6PD enzyme in red blood cells, typically reported in units per gram of hemoglobin (U/gHb). Moreover, the normal reference range usually falls between 7.0 and 10.0 U/gHb, depending on laboratory standards. In addition, low G6PD activity levels indicate G6PD deficiency, which increases the risk of hemolytic anemia. Conversely, normal enzyme levels suggest healthy red blood cell function, with no significant oxidative stress vulnerability. Furthermore, the test employs methods like spectrophotometry or fluorescent spot testing, which are widely used for accurate enzyme activity measurement. Above all, healthcare providers may perform this test on patients with unexplained hemolysis, ensuring proper diagnosis. Likewise, it is a vital screening tool for individuals from high-prevalence regions, such as those with African, Mediterranean, or Asian ancestry. Consequently, early identification of G6PD deficiency helps avoid triggers, preventing severe complications. Lastly, modern test methods ensure reliable and precise results, supporting effective clinical decision-making.

Clinical Significance of Glucose-6-phosphate dehydrogenase (G6PD) Test

The G6PD Test plays a critical role in diagnosing and managing G6PD deficiency, a common enzymatic disorder. Firstly, it helps identify individuals prone to hemolytic anemia, triggered by oxidative stress. Moreover, the test aids in assessing red blood cell stability, especially under conditions like infections, drug exposure, or fava bean consumption. In addition, it guides clinicians in preventing complications, ensuring patients avoid known triggers of hemolysis. Furthermore, the G6PD Test supports early diagnosis, which is essential for reducing severe health risks. Above all, it is valuable in screening individuals from high-risk populations, including those of African, Mediterranean, or Asian descent. Likewise, it helps monitor the enzyme activity in patients undergoing treatments, ensuring safe and effective therapies. Consequently, the test provides crucial insights into the patient’s red blood cell health, enabling tailored care. Lastly, it is essential for prenatal and neonatal care, to identify G6PD deficiency early for better outcomes.
