What is a CD55 (PNH Marker) Test in Gurugram ?
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. If you have these symptoms, GetVisit offers booking and home collection across Manesar, DLF Phase 1, and other parts of Gurugram.
How is CD55 (PNH Marker) performed?
This test needs a urine sample, not a blood draw. Collect a clean mid-stream sample in the sterile container GetVisit provides, ideally the first morning void, and hand it to the collection agent in Manesar or DLF Phase 1, Gurugram or drop it at a partnered lab. It is dispatched to the NABL-accredited lab and your digital report follows the same day for most routine urine tests.
How accurate is CD55 (PNH Marker)?
GetVisit's NABL-accredited labs serving Manesar and DLF Phase 1, Gurugram 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 Manesar or DLF Phase 1, Gurugram 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 Gurugram
Diet and fasting:
Provide a clean mid-stream urine sample: pass the first bit into the toilet, collect the middle portion in the sterile container, and submit it within about 2 hours.
What to carry:
Have your doctor's referral and photo ID ready; earlier reports for the same test are useful for tracking trends.
Medication guidance:

Why Take a CD55 (PNH Marker) Test in Gurugram ?
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 Gurugram?
Gurugram's dense corporate population, severe NCR air pollution, high diabetes and cardiovascular burden, extreme seasonal temperatures, and monsoon infection risk make regular preventive diagnostic testing an essential health investment 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 Gurugram 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?
Your result is read against the reference range printed on your GetVisit report for your age and sex, and always alongside your symptoms and history. A single value slightly outside the range does not by itself confirm a problem, your doctor decides whether it is significant. The specific high and low patterns for this test are explained in the FAQs below.
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?
Once your results appear in your GetVisit profile, discuss them with your doctor or a GetVisit-verified specialist. Your doctor will interpret each value in the context of your full health history, current medications, and symptoms, and advise on the next step: lifestyle change, repeat testing, medication adjustment, or specialist referral. All GetVisit reports are stored permanently and can be shared with any doctor instantly.
