What is the normal range for CD58 (PNH Marker)?

Reference ranges for CD58 (PNH Marker) are determined by the laboratory based on values measured in healthy populations and are printed alongside your result on the report. Your doctor will explain whether your result is within normal limits, borderline, or significantly abnormal, and advise on what action, if any, is clinically indicated.

Do I need to fast before CD58 (PNH Marker)?

Fasting requirements depend on the specific test. Your doctor will advise when they order it. As a general precaution, avoid alcohol, a heavy meal, and strenuous exercise the evening before any blood test. If fasting is required, it is typically 8 to 12 hours with water freely allowed throughout.

Can I take my regular medication before CD58 (PNH Marker)?

For most tests, continue taking all prescribed medication as usual unless your doctor has specifically asked you to stop. Some medications alter specific marker levels and may affect interpretation. Always inform lab staff about all medications, supplements, and herbal remedies you are taking when you arrive for the test.

What is a CD58 (PNH Marker) Test in Nagpur ?

What is CD58 (PNH Marker)?

This test measures the amount of CD58 protein on the surface of blood cells. CD58 helps immune cells recognize and talk to each other. Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.

What does CD58 (PNH Marker) measure?

Measuring CD58 can reveal abnormal or missing surface proteins on blood cells. Such changes may appear in paroxysmal nocturnal hemoglobinuria (PNH) and related bone marrow disorders. Doctors use CD58 together with other flow cytometry markers to help diagnose PNH, to check how active the disease is, and to monitor response to treatment. The test can be useful when someone has unexplained anemia, dark urine, or unusual blood clots.

What symptoms suggest CD58 (PNH Marker) may be needed?

A doctor may recommend CD58 (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 Nagpur, with lab slots and home collection in Mahal, Wardhaman Nagar, and nearby areas.

How is CD58 (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 Mahal or via home pickup in Wardhaman Nagar, Nagpur. GetVisit handles labelling and NABL lab dispatch.

How accurate is CD58 (PNH Marker)?

GetVisit's NABL-accredited labs serving Mahal and Wardhaman Nagar, Nagpur 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 CD58 (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 Mahal or Wardhaman Nagar, Nagpur is just as safe as visiting a lab.

Did you know?

PNH markers include flow cytometry demonstrating absent or reduced GPI‑anchored proteins (CD55 and CD59) on red cells and granulocytes.

Why Take a CD58 (PNH Marker) Test in Nagpur ?

When does a doctor order CD58 (PNH Marker)?

CD58 (PNH Marker) is usually part of a flow cytometry panel used to evaluate suspected PNH or related bone marrow disorders. Doctors may order it when a patient has unexplained anemia, fatigue, dark urine, or blood clots.

Who should get CD58 (PNH Marker) done in Nagpur?

Nagpur's growing population, extreme summer heat with high dehydration and kidney-stone risk, oil- and sugar-rich diet driving diabetes and heart disease, and seasonal monsoon infections make regular preventive diagnostic testing worthwhile for residents across the city. Those who benefit most from regular CD58 (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 Nagpur is consistently more cost-effective than treating advanced disease.

What conditions can CD58 (PNH Marker) help diagnose?

The test helps detect blood cell clones that lack normal surface proteins. Abnormal results most often reflect an acquired condition such as PNH rather than lifestyle causes. A family history of bone marrow disease or unexplained hemolysis may make testing more important.

What do CD58 (PNH Marker) results mean?

Higher or positive results: PNH is typically Coombs-negative. Lower or negative results: PNH is typically Coombs-negative. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.

How often should CD58 (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 CD58 (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.

What are the markers for PNH?

PNH markers include flow cytometry demonstrating absent or reduced GPI‑anchored proteins (CD55 and CD59) on red cells and granulocytes. Laboratory evidence of hemolysis, elevated LDH, indirect bilirubin, reticulocytosis, low haptoglobin and hemoglobinuria, is typical. Historical sucrose lysis or Ham (acidified serum) tests may be positive. Patients may also show marrow abnormalities or thrombotic markers (e.g. elevated D‑dimer).

What is CD55 and CD59 in PNH?

CD55 (decay‑accelerating factor) and CD59 (protectin) are GPI‑anchored complement regulators on red blood cells. In PNH, PIGA gene–mediated loss of GPI anchors removes CD55 and CD59, allowing unchecked complement activation. CD55 disrupts C3/C5 convertases; CD59 prevents membrane attack complex formation. Their absence causes intravascular hemolysis, hemoglobinuria, anemia and fatigue, with increased thrombosis risk.

What is the gold standard for diagnosing PNH?

The gold standard for diagnosing paroxysmal nocturnal hemoglobinuria (PNH) is flow cytometry demonstrating absence or reduced expression of GPI‑anchored proteins (especially CD55 and CD59) on red blood cells and granulocytes. FLAER‑enhanced flow cytometry (using fluorescent aerolysin) provides higher sensitivity and is preferred for detecting PNH clones in granulocytes and monocytes, confirming diagnosis and guiding management.

Is PNH Coombs positive or negative?

PNH is typically Coombs-negative. Hemolysis is complement-mediated due to loss of GPI-anchored proteins (CD55/CD59) on red cells, causing intravascular destruction without autoantibodies. Therefore the direct antiglobulin (Coombs) test is usually negative. Rarely, concomitant autoimmune hemolysis can yield a positive Coombs, but classic PNH is diagnosed by flow cytometry showing CD55/CD59 deficiency.

Can I take my diabetes medication before CD58 (PNH Marker)?

If you take insulin or diabetes tablets and are fasting for CD58 (PNH Marker), ask your doctor whether to delay the dose until after the sample is collected, to avoid a low-sugar episode.

Can I drink coffee or tea before CD58 (PNH Marker)?

If CD58 (PNH Marker) needs fasting, avoid tea and coffee (even without sugar) during the fasting window, as they can affect some results; plain water is fine. If no fasting is required, your usual drinks are okay.
