What is a CD22 (Pan B Cell Marker) Test in Gurugram ?

What is CD22 (Pan B Cell Marker)?

This test measures the CD22 protein on the surface of B lymphocytes. CD22 is a marker used to identify and count B cells. Deficiencies develop over months before symptoms appear. Because symptoms like fatigue and hair loss are non-specific, targeted blood testing is the only reliable way to confirm the diagnosis.

What does CD22 (Pan B Cell Marker) measure?

It helps control B cell activity and the immune response. Measuring CD22 is important for detecting and classifying B‑cell leukemias and lymphomas. It is also used to monitor treatment response and to follow B‑cell recovery after therapy. Doctors use flow cytometry or tissue staining to measure CD22.

What symptoms suggest CD22 (Pan B Cell Marker) may be needed?

A doctor may recommend CD22 (Pan B Cell Marker) when a patient reports persistent fatigue, hair thinning, brittle nails, bone or joint pain, frequent infections, poor wound healing, numbness or tingling in the hands or feet, and low mood or poor concentration. In Gurugram, you can book this test online with home collection available in South City, DLF Phase 1, and beyond.

How is CD22 (Pan B Cell Marker) performed?

At a GetVisit-partnered lab in South City or DLF Phase 1, Gurugram, a certified phlebotomist cleans the inner elbow, locates a vein, and draws the required blood (typically 5 to 10 mL). The procedure takes 3 to 5 minutes. You feel a brief pinch at insertion and mild pressure during collection, then can eat, drive, and resume all activities immediately afterwards.

How accurate is CD22 (Pan B Cell Marker)?

Every GetVisit sample from South City, DLF Phase 1, and across Gurugram is processed at NABL-accredited labs that use internationally calibrated reference standards, pass external quality assessments, and maintain internal quality control at every shift. Reports are accepted by all major hospital networks, specialists, and insurance providers in India.

Are there any risks to CD22 (Pan B Cell Marker)?

Beyond a brief pinch, CD22 (Pan B Cell Marker) carries almost no risk. Keep the arm relaxed during the draw, press gently on the site afterwards, and avoid heavy lifting with that arm for about an hour.

Did you know?

CD22 is a B‑cell–specific surface glycoprotein (Siglec‑2) used as a marker of mature B lymphocytes in immunophenotyping.

CD22 (Pan B Cell Marker) Test Preparation in Gurugram

Fasting and diet:

Fasting is not necessary for this test. Drinking water freely beforehand actually makes sample collection easier.

What to bring:

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

Medication:

Avoid supplements of the nutrient being measured for a day or two before the test; taking one shortly before can inflate the reading.

Timing and slots:

Morning appointments suit most tests, when the body's markers are most stable. GetVisit home collection in Gurugram starts at 6:00 AM, including DLF Phase 3 and Golf Course Road.

CD22 (Pan B Cell Marker) Test Parameters in Gurugram

Single standalone test:

CD22 (Pan B Cell Marker). Can be ordered individually or as part of a preventive health package on GetVisit.

Why Take a CD22 (Pan B Cell Marker) Test in Gurugram ?

When does a doctor order CD22 (Pan B Cell Marker)?

CD22 (Pan B Cell Marker) is commonly included in flow cytometry and lymphoma/leukemia immunophenotyping panels. Doctors may order it when you have enlarged lymph nodes, unexplained bruising, fatigue, recurring infections, or abnormal blood counts.

Who should get CD22 (Pan B Cell Marker) done in Gurugram?

Vitamin D deficiency is severe in Gurugram: winter smog blocks UV for months and the corporate workforce spends long hours indoors in Cyber City and DLF. B12 deficiency is also common among vegetarian professionals across Sushant Lok and South City. Those who benefit most from regular CD22 (Pan B Cell Marker) testing include people on restrictive diets, those recovering from illness, and anyone with persistent tiredness. Confirming a deficiency in Gurugram allows correctly dosed supplementation rather than guesswork.

What conditions can CD22 (Pan B Cell Marker) help diagnose?

It helps diagnose and classify B‑cell leukemias and lymphomas and monitor response to therapy. Abnormal results can come from malignancy, immune disorders, infections, or B‑cell–targeting drugs, and a family history of blood cancers may prompt testing.

What do CD22 (Pan B Cell Marker) results mean?

Vitamin D below 20 ng/mL: deficiency , loading dose (typically 60,000 IU weekly for 8–12 weeks) followed by maintenance. Vitamin D 20–30 ng/mL: insufficiency , moderate supplementation. Above 100 ng/mL: toxicity risk. Vitamin B12 below 200 pg/mL: deficiency , oral or injectable supplementation depending on cause.

How often should CD22 (Pan B Cell Marker) be repeated?

After starting supplementation, recheck at 8 to 12 weeks to confirm levels are correcting, then every 6 to 12 months once replete. People with ongoing risk factors, restrictive diets, malabsorption, or limited sun exposure, benefit from annual screening even without symptoms.

What happens after CD22 (Pan B Cell Marker) results are ready?

Reports arrive digitally and remain in your GetVisit history, so repeat tests can be tracked over months and years. Review anything unexpected with your doctor before changing medication or lifestyle, and use the app to book a follow-up if needed.

Frequently asked questions

What is CD22 a marker for?plus

CD22 is a B‑cell–specific surface glycoprotein (Siglec‑2) used as a marker of mature B lymphocytes in immunophenotyping. It regulates B‑cell receptor signaling and is present on most mature B cells but usually absent on pro‑B cells and plasma cells. Clinically, CD22 expression helps identify and target B‑cell leukemias and lymphomas.

What are the markers for Pan B cells?plus

Pan-B cell markers include surface and intracellular proteins consistently expressed across B-cell stages: CD19, CD20, CD22, CD79a/CD79b, and PAX5, often with surface immunoglobulin (IgM/IgD) positivity. Additional supportive markers used in diagnostics include CD45 and CD21, while markers like CD10 or CD23 help subtype B-cell populations rather than define the pan‑B lineage.

Which B cells express CD22?plus

CD22 (Siglec‑2) is a B‑cell–restricted surface lectin expressed mainly on mature B cells , including naïve, memory, follicular and marginal‑zone subsets , from late pre‑B/immature stages onward. Expression is reduced on activated B cells and largely lost on plasmablasts and terminally differentiated plasma cells. It functions in B‑cell signaling and regulation of B‑cell receptor responses.

Is CD20 a pan-B cell marker?plus

No , CD20 is a widely expressed B‑cell antigen present on most mature and many late precursor B cells, making it a common B‑cell marker and therapeutic target. However, it is not truly pan‑B: very early B‑lineage cells (some pro‑B) and terminally differentiated plasmablasts/plasma cells lack CD20, affecting diagnostic staining and response to anti‑CD20 therapies.

Can I exercise before CD22 (Pan B Cell Marker)?plus

Avoid strenuous exercise for 12 to 24 hours before CD22 (Pan B Cell Marker), since intense activity can temporarily change several blood markers. Light everyday movement is fine.

Do I need a doctor's prescription to book CD22 (Pan B Cell Marker)?plus

You can book CD22 (Pan B Cell 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.
