What is a CD55 (PNH Marker) Test in Chennai ?
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. Low or absent CD55 is a hallmark of paroxysmal nocturnal hemoglobinuria (PNH). Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.
What does CD55 (PNH Marker) measure?
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. Laboratory analysis produces a numerical result compared against a reference range derived from a healthy population of equivalent age and gender. Clinical context determines whether a borderline result is significant.
What symptoms suggest CD55 (PNH Marker) may be needed?
A doctor may order 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 Chennai, residents of OMR and Kodambakkam commonly present for this test after noticing these symptoms during a routine or preventive consultation.
How is CD55 (PNH Marker) performed?
Whether you visit a walk-in lab in OMR or book home collection in Kodambakkam, Chennai, the process is the same. A trained phlebotomist performs a brief, sterile venipuncture, barcodes the sample for tracking, and dispatches it to the NABL lab. Your digital report is available in the GetVisit app the same day for most blood tests.
How accurate is CD55 (PNH Marker)?
NABL-accredited laboratory results are analytically reliable. GetVisit's logistics network maintains cold-chain transport from collection to the processing lab, preserving sample integrity. Quality control is independently audited by NABL at regular intervals.
Are there any risks to CD55 (PNH Marker)?
There are no significant medical risks beyond those of a standard blood draw. Vasovagal fainting (rare) is more likely if you are fasting, anxious, or dehydrated. Drink 2 to 3 glasses of water before the appointment, remain seated during the draw, and stay seated for 2 to 3 minutes afterwards. Inform the phlebotomist if you have fainted during previous draws.
CD55 (PNH Marker) Test Preparation in Chennai
Fasting and dietary instructions:
No special fasting needed. Avoid heavy fatty meals and alcohol the evening before as a general precaution.
Medication guidance:
Continue all regularly prescribed medication unless your doctor has specifically instructed otherwise. Inform lab staff about all prescription drugs, supplements, herbal preparations, and protein powders you are taking.
What to bring:
Bring your doctor's prescription or test requisition, a valid photo ID, and your corporate health insurance card if using cashless OPD. Wear short sleeves or clothing with sleeves that roll up easily.
Timing:
Book the earliest available morning slot. For fasting tests, an overnight fast followed by a morning draw represents the optimal balance between adequate fasting duration and test accuracy.

Why Take a CD55 (PNH Marker) Test in Chennai ?
When does a doctor order CD55 (PNH Marker)?
CD55 (PNH Marker) is ordered when a doctor needs objective laboratory data to confirm a diagnosis, follow up a previously abnormal result, or complete a pre-operative assessment.
Who should get CD55 (PNH Marker) done in Chennai?
Chennai's 11 million metro population, tropical climate, northeast monsoon flooding risk, and one of India's highest cardiovascular and diabetes disease burdens make regular diagnostic testing an essential part of preventive health management across the city. 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. Adults above 30 in Chennai benefit from periodic health screening that includes CD55 (PNH Marker) as part of a broader preventive panel. Residents of Mylapore, Kodambakkam, 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?
The conditions diagnosable through CD55 (PNH Marker) depend on the specific markers the test measures. Results either confirm a suspected diagnosis, support a clinical suspicion requiring further investigation, or effectively exclude the condition the test was screening for.
What do CD55 (PNH Marker) results mean?
Results are compared against the laboratory's reference range for your age and gender. A value outside the reference range does not automatically confirm disease , clinical context, symptoms, and sometimes a repeat test determine significance. Your GetVisit report shows the reference range alongside your measured value.
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.
