What is a CD55 (PNH Marker) Test in Bengaluru ?
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 Bengaluru, you can book this test online with home collection available in BTM Layout, Indiranagar, and beyond.
How is CD55 (PNH Marker) performed?
You provide a urine sample rather than blood. Follow the container instructions for a clean mid-stream catch, avoid contamination from soap or toilet water, and submit it within two hours of collection at a lab in BTM Layout or via home pickup in Indiranagar, Bengaluru. GetVisit handles labelling and NABL lab dispatch.
How accurate is CD55 (PNH Marker)?
GetVisit's NABL-accredited labs serving BTM Layout and Indiranagar, Bengaluru process urine samples on calibrated analysers under strict quality control. Accuracy depends on a clean mid-stream sample delivered promptly, so following the collection instructions is important. Reports are accepted by hospitals, specialists, and insurers across India.
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 BTM Layout or Indiranagar, Bengaluru 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).

Why Take a CD55 (PNH Marker) Test in Bengaluru ?
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 Bengaluru?
Bengaluru's 12 million metropolitan population, year-round dengue risk, rising NAFLD and diabetes burden among its massive IT workforce, and rapidly growing outer areas with variable water quality make regular preventive diagnostic testing an important part of health management for residents across every neighbourhood. Adults above 30 in Bengaluru benefit from periodic health screening that includes CD55 (PNH Marker) as part of a broader preventive panel. Residents of MG Road, Bellandur, and across the city with chronic conditions, those on long-term medication, and individuals with a relevant family history should test at the frequency their specialist recommends.
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 CD55 (PNH Marker) results are ready?
Reports arrive digitally and remain in your GetVisit history, so repeat tests can be tracked over months and years. Review anything unexpected with your doctor before changing medication or lifestyle, and use the app to book a follow-up if needed.
