What is a CD55 (PNH Marker) Test in Patna ?
What is CD55 (PNH Marker)?
The CD55 (PNH Marker) test measures the amount of CD55 protein on red blood cells. CD55 helps protect blood cells from the body's complement system, which can destroy cells if unchecked. Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.
What does CD55 (PNH Marker) measure?
Low or absent CD55 is a hallmark of paroxysmal nocturnal hemoglobinuria (PNH). Detecting reduced CD55 helps explain unexplained anemia, dark urine, and unusual blood clots. Doctors use this test with other markers, like CD59, usually by flow cytometry. It helps confirm a PNH diagnosis, estimate the size of the affected cell population, and monitor response to treatments that block complement activity.
What symptoms suggest CD55 (PNH Marker) may be needed?
A doctor may recommend CD55 (PNH Marker) when a patient reports any symptom your doctor has identified as requiring objective laboratory investigation, including unexplained fatigue, unexplained weight change, persistent pain, fever, or abnormal bleeding. In Patna, you can book this test online with home collection available in Phulwari Sharif, Patliputra Colony, and beyond.
How is CD55 (PNH Marker) performed?
No needle is involved. For home service in Phulwari Sharif or Patliputra Colony, Patna, GetVisit delivers a sterile container, you provide a clean mid-stream urine sample, and a certified agent collects and transports it to the NABL lab under proper conditions. Your report appears in the GetVisit app when results are authorised.
How accurate is CD55 (PNH Marker)?
Urine results are reliable when the sample is collected cleanly and transported quickly. GetVisit's Patna network handles prompt, temperature-appropriate transport from Phulwari Sharif or Patliputra Colony to the NABL lab, and quality control is independently audited by NABL.
Are there any risks to CD55 (PNH Marker)?
There is no medical risk. Providing a urine sample is completely non-invasive, with no needle and no discomfort. The only thing to get right is a clean collection: follow the container instructions to avoid contamination that could affect the result. Home collection in Phulwari Sharif or Patliputra Colony, Patna is just as safe as visiting a lab.
Did you know?
CD59 is a GPI‑anchored complement regulatory protein on blood cell membranes that prevents formation of the membrane attack complex (C5b-C9).
CD55 (PNH Marker) Test Preparation in Patna
Before you come:

Continue your regular medicines unless your doctor has told you otherwise.
Documents and clothing:
Bring your doctor's prescription, a valid photo ID, and your insurance card if you're using cashless OPD. Loose sleeves make collection easier.

CD55 (PNH Marker). Can be ordered individually or as part of a preventive health package on GetVisit.
Why Take a CD55 (PNH Marker) Test in Patna ?
When does a doctor order CD55 (PNH Marker)?
CD55 (PNH Marker) is usually ordered as part of a hemolysis or PNH flow cytometry panel that also checks CD59 and other markers. Doctors may request it for unexplained anemia, dark or cola-colored urine, or unusual blood clots.
Who should get CD55 (PNH Marker) done in Patna?
Patna's Ganga floodplain geography and monsoon waterborne-infection burden, widespread iron and vitamin deficiency, rising diabetes and cardiovascular disease, and hot summers make regular preventive diagnostic testing especially valuable for residents across the city. Those who benefit most from regular CD55 (PNH Marker) testing include adults above 40, people with sedentary lifestyles or BMI above 25, those managing chronic conditions, smokers, and anyone whose previous result was borderline. Early detection through regular testing in Patna is consistently more cost-effective than treating advanced disease.
What conditions can CD55 (PNH Marker) help diagnose?
It helps diagnose and monitor paroxysmal nocturnal hemoglobinuria and related bone marrow disorders. Abnormal results come from loss of GPI-anchored proteins on blood cells due to acquired mutations and from disease activity; certain blood disorders or treatments can affect results. A family history of unexplained hemolysis or blood disorders may prompt testing.
What do CD55 (PNH Marker) results mean?
Results are interpreted in context, not in isolation. GetVisit shows your measured value next to the laboratory reference range, and your doctor reads it together with your clinical picture and any earlier results. See the FAQs below for what typical high or low values can mean for this test.
How often should CD55 (PNH Marker) be repeated?
For preventive screening with a normal baseline: annually for most adults above 35. For monitoring a known condition: at the interval your specialist recommends, typically every 3 to 6 months for active conditions and annually for stable, well-controlled ones.
What happens after your CD55 (PNH Marker) results are ready?
Book a follow-up consultation after reviewing your results. GetVisit stores your reports alongside your previous test history, so your doctor sees your full health trend, not just today's snapshot. This longitudinal context significantly improves the clinical value of each repeat test.
