What is a CD55 (PNH Marker) Test in Howrah ?
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?
CD55 (PNH Marker) is ordered when your doctor needs objective laboratory data, either to follow up a symptom, check a previous result, or complete a routine assessment. Your doctor will advise whether it is the right test for your situation. Sample collection for Howrah is available at partner labs, with home collection in many areas including Domjur and Jagacha; you can confirm availability for your address at booking.
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 Domjur or Jagacha, Howrah or drop it at a partnered lab. It is dispatched to the NABL-accredited lab and your digital report follows once the laboratory releases it, usually within 24 to 48 hours.
How accurate is CD55 (PNH Marker)?
GetVisit's NABL-accredited labs serving Domjur and Jagacha, Howrah 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 Domjur or Jagacha, Howrah 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 Howrah ?
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 Howrah?
Howrah's dense industrial and trading economy, monsoon waterlogging and waterborne-infection burden, commute links into Kolkata, and rising diabetes and cardiovascular prevalence make regular preventive testing worthwhile citywide. Adults above 30 in Howrah benefit from periodic health screening that includes CD55 (PNH Marker) as part of a broader preventive panel. Residents of Domjur, Jagacha, 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?
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 your CD55 (PNH Marker) results are ready?
You will be notified as soon as the laboratory releases your results, usually within 24 to 48 hours. Open the report in the GetVisit app to see each value beside its reference range, share it with your doctor in a tap, or book a specialist consultation to talk it through.
