What is a CD55 (PNH Marker) Test in Delhi ?

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. GetVisit makes testing convenient in Delhi, with lab slots and home collection in Lajpat Nagar, Rohini, and nearby areas.

How is CD55 (PNH Marker) performed?

No needle is involved. For home service in Lajpat Nagar or Rohini, Delhi, 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)?

GetVisit's NABL-accredited labs serving Lajpat Nagar and Rohini, Delhi 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 Lajpat Nagar or Rohini, Delhi 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 Delhi

Fasting instructions:

Collect a clean-catch mid-stream sample in the container provided, ideally the first urine of the morning, and hand it in promptly for the most reliable result.

What to bring along:

Carry your test requisition, a government-issued ID, and any previous reports so results can be compared over time.

Managing medication:

Tell the collection staff about any prescription medicines, supplements, or herbal products you're using, and keep taking them unless advised otherwise.

Timing:

An early slot works best, especially for fasting tests. Home collection is available across Hauz Khas, Rohini, and the rest of Delhi.

CD55 (PNH Marker) Test Parameters in Delhi

Single standalone test:

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 Delhi ?

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 Delhi?

Delhi's 30+ million population, India's most severe urban air pollution, one of the country's highest combined diabetes and cardiovascular disease burdens, extreme seasonal temperature range (from 3°C in January to 48°C in May), and monsoon infection risk across Dwarka, Rohini, Shahdara, and Uttam Nagar make regular preventive diagnostic testing an essential part of health management for all city residents. 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 Delhi 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?

After the lab authorises your results, the report is uploaded to your GetVisit account and saved for future comparison. If anything falls outside the expected range, your doctor can advise whether it needs a repeat test, a lifestyle change, or a specialist opinion.

What is CD59 in PNH?plus

CD59 is a GPI‑anchored complement regulatory protein on blood cell membranes that prevents formation of the membrane attack complex (C5b–C9). In PNH, PIGA mutations cause loss of CD59 from red cells and other blood cells, permitting unchecked complement‑mediated intravascular hemolysis and increased thrombosis risk. Flow cytometry detects CD59 deficiency for diagnosis and guides complement‑inhibitor therapy.

What are the markers for PNH?plus

PNH is marked by loss of GPI-anchored proteins, particularly CD55 and CD59, on red cells and leukocytes, detected by flow cytometry (often using FLAER). Laboratory markers include intravascular hemolysis (hemoglobinuria, elevated LDH, low haptoglobin, indirect hyperbilirubinemia, reticulocytosis), cytopenias, and an increased tendency for thrombosis. Historic tests include sucrose lysis or Ham test, but flow cytometry is diagnostic.

What do CD55 and CD59 do?plus

CD55 (decay-accelerating factor) and CD59 (protectin) are membrane proteins that protect host cells from complement-mediated damage. CD55 disrupts formation and accelerates decay of C3/C5 convertases, limiting complement activation. CD59 prevents membrane attack complex formation by blocking C9 polymerization, avoiding cell lysis. Both are broadly expressed on blood cells and endothelium; loss increases complement-driven injury.

What is the gold standard test for PNH?plus

The gold standard test for paroxysmal nocturnal hemoglobinuria (PNH) is flow cytometry demonstrating deficiency of GPI‑anchored proteins on blood cells. Multiparameter flow cytometry uses antibodies to CD55 and CD59 and FLAER (which binds GPI anchors) on red cells, granulocytes, and monocytes to detect and quantify PNH clones with high sensitivity and specificity.

Can I take my diabetes medication before CD55 (PNH Marker)?plus

If you take insulin or diabetes tablets and are fasting for CD55 (PNH Marker), ask your doctor whether to delay the dose until after the sample is collected, to avoid a low-sugar episode.

Do I need a doctor's prescription to book CD55 (PNH Marker)?plus

You can book CD55 (PNH Marker) on GetVisit with or without a prescription, though a doctor's advice helps with interpreting the result. Cashless OPD may require a referral, depending on your insurer.
