Doctor's Notes
Reviewed by Dr Pasupathy Arumugam — MBBS, MD (Pathology) · Reg. No. 21521
"G-6-PD deficiency is a common X-linked genetic disorder affecting red blood cells. Early diagnosis through quantitative testing helps in managing symptoms, avoiding triggers like certain drugs or fava beans, and monitoring treatment to prevent hemolytic episodes."

- Hemolyzed sample
- Insufficient sample volume
- Improperly labeled or stored sample
Understanding Your Results
Low G-6-PD activity
Indicates G-6-PD deficiency, which may lead to hemolytic anemia. Severity can vary based on enzyme level and triggers.
Action: Consult a physician for further evaluation and management. Avoid known triggers like fava beans and certain drugs.
Normal G-6-PD activity
Suggests no significant enzyme deficiency. However, symptoms may persist due to other causes.
Action: If symptoms continue, additional tests may be recommended by your doctor.
Intermediate G-6-PD activity
May indicate carrier status (especially in females) or partial deficiency. Requires clinical correlation.
Action: Discuss results with a healthcare provider for personalized advice.
Consult a doctor if you experience symptoms like jaundice, anemia, or dark urine, or if you have a family history of G-6-PD deficiency. After a positive test result, seek medical guidance for management and trigger avoidance.
Limitations
- ⚠May not detect all genetic variants, especially in heterozygous females
- ⚠Cannot differentiate between specific G-6-PD variants
- ⚠Results may be influenced by sample handling and storage conditions
Risks & Considerations
- ●Minor pain or bruising at the puncture site
- ●Rare risk of infection or fainting
Interfering Factors
- ●Recent blood transfusion (may yield false normal results)
- ●Acute hemolytic episode (can temporarily lower enzyme levels)
- ●Hemolyzed sample
- ●Certain medications (e.g., primaquine) that may affect enzyme stability
