Frequently Asked Questions
What does the Flow Cytometry - CD64 test measure?
It quantifies CD64 (FcγRI) expression on the surface of monocytes and other leukocytes using flow cytometry. CD64 is an activation marker that rises significantly during bacterial sepsis and systemic inflammation.
Is fasting required for this test?
No, fasting is not required. CD64 levels are not affected by recent food intake, and the sample can be collected at any time during laboratory working hours.
What conditions cause elevated CD64 levels?
Elevated CD64 is primarily seen in bacterial sepsis, severe systemic inflammation, autoimmune flares, and certain hematologic disorders. It is increasingly used as an early biomarker to differentiate septic from non-septic inflammation.
How is the sample collected?
The test requires venous whole blood collected in an EDTA or Heparin tube, or a bone marrow aspirate. The sample is processed promptly to preserve cell surface antigen integrity for flow cytometric analysis.
Can medications affect CD64 results?
Yes. Corticosteroids, immunosuppressants, and certain biologic agents can suppress CD64 expression. Always inform your doctor about current medications so results can be interpreted in clinical context.
How is the report delivered?
Verified PDF reports are available within 24–48 hours via www.drpatholab.in or through WhatsApp/Email, issued by a qualified pathologist with clinical correlation remarks.
