What is a CD4 (Pan T Cell Marker) Test in Delhi ?

What is CD4 (Pan T Cell Marker)?

The CD4 (Pan T cell marker) test measures the number of CD4-positive T lymphocytes in your blood. These cells help coordinate the immune response and signal other cells to fight infections. Accurate organism identification is clinically essential , typhoid, dengue, and malaria each require different treatment, and the wrong empirical approach delays recovery.

What does CD4 (Pan T Cell Marker) measure?

CD4 levels show how well your immune system can respond to germs. Doctors use the test to detect and monitor HIV and other causes of immune suppression. It helps predict risk for opportunistic infections and guides treatment choices. Clinicians also check CD4 during chemotherapy, after transplants, or when recurrent infections occur.

What symptoms suggest CD4 (Pan T Cell Marker) may be needed?

A doctor may recommend CD4 (Pan T Cell Marker) when a patient reports sudden fever (above 38.5°C), body aches and chills, persistent headache, nausea or vomiting, abdominal pain, skin rash, joint pain, and extreme fatigue. GetVisit makes testing convenient in Delhi, with lab slots and home collection in Vasant Kunj, South Extension, and nearby areas.

How is CD4 (Pan T Cell Marker) performed?

Collection is a routine blood draw. Using a single-use sterile needle, the phlebotomist takes a small sample from a vein in your arm; GetVisit's team in Vasant Kunj and South Extension, Delhi then barcodes and transports it under controlled conditions to the NABL lab.

How accurate is CD4 (Pan T Cell Marker)?

Every GetVisit sample from Vasant Kunj, South Extension, and across Delhi 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 CD4 (Pan T Cell Marker)?

A blood draw for CD4 (Pan T Cell Marker) is very safe. Occasionally there is minor bruising or light-headedness; sitting for a couple of minutes afterwards at the Vasant Kunj or South Extension, Delhi collection point usually prevents this.

Did you know?

A pan‑T cell marker is a surface protein expressed on nearly all T lymphocytes (for example, CD3) used to identify and quantify T‑cell populations.

CD4 (Pan T Cell Marker) Test Preparation in Delhi

Medication guidance:

There's usually no need to stop your regular medication; just let the staff know what you take.

Diet and fasting:

There is no need to skip food or drink for this test. Staying well hydrated beforehand simply makes the sample easier to collect.

When to book:

An early slot works best, especially for fasting tests. Home collection is available across Janakpuri, Karol Bagh, and the rest of Delhi.

What to carry:

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

CD4 (Pan T Cell Marker) Test Parameters in Delhi

Single standalone test:

CD4 (Pan T Cell Marker). Can be ordered individually or as part of a preventive health package on GetVisit.

Why Take a CD4 (Pan T Cell Marker) Test in Delhi ?

When does a doctor order CD4 (Pan T Cell Marker)?

CD4 (Pan T Cell Marker) is commonly included in HIV monitoring panels and immune function profiles. Doctors may order it for people with unexplained recurrent infections, weight loss, fevers, or suspected immunodeficiency.

Who should get CD4 (Pan T Cell 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. Anyone with fever or flu-like illness in Delhi, especially during and after the monsoon, benefits from prompt CD4 (Pan T Cell Marker) testing, as do travellers returning from endemic areas and people caring for someone already infected. Residents of Karol Bagh, Dwarka, and flood-prone localities face higher seasonal exposure to mosquito- and water-borne infections.

What conditions can CD4 (Pan T Cell Marker) help diagnose?

It helps diagnose and follow HIV, track immune recovery during treatment, and assess chemotherapy or transplant effects. Low or high counts can result from infections, autoimmune disease, medications like steroids or chemotherapy, and inherited immune disorders. Family history of immune problems may prompt earlier or repeated testing.

What do CD4 (Pan T Cell Marker) results mean?

Results are interpreted in context, not in isolation. GetVisit shows your measured value next to the laboratory reference range, and your doctor reads it together with your clinical picture and any earlier results. See the FAQs below for what typical high or low values can mean for this test.

How often should CD4 (Pan T Cell Marker) be repeated?

Infection tests are ordered when symptoms are present rather than on a fixed schedule. Repeat testing may be needed to confirm recovery, to check clearance after treatment, or if fever recurs. During Delhi's monsoon fever season, prompt retesting is advised for any new febrile illness.

What happens after CD4 (Pan T Cell Marker) results are ready?

Your GetVisit digital report is delivered to your phone as soon as results are authorised. Share it directly with your doctor via the app, or book a consultation with a GetVisit-verified specialist on the same platform. Critical values outside a safe range are flagged by the laboratory for urgent clinical review.

What is a pan-T cell marker?plus

A pan‑T cell marker is a surface protein expressed on nearly all T lymphocytes (for example, CD3) used to identify and quantify T‑cell populations. It confirms T‑cell lineage in blood and tissue samples, aids immunophenotyping by flow cytometry or immunohistochemistry, and helps distinguish T cells from B cells or NK cells in diagnostic and research settings.

What are the markers for CD4 T cells?plus

CD4 T cells are CD3+ CD4+ lymphocytes. Subset and activation markers include CD45RA (naive) vs CD45RO (memory), CCR7 and CD62L (central memory), CD28 (co‑stimulation). Regulatory T cells: CD4+ CD25high FOXP3+ with low CD127. Activation/exhaustion markers: CD69, HLA‑DR, CD25, PD‑1 and CTLA‑4. CXCR5 marks T follicular helper cells. These markers are used in flow cytometry and immunophenotyping.

What is CD62L a marker for?plus

CD62L (L‑selectin) is an adhesion receptor expressed on leukocytes that serves as a marker of naïve and central memory T cells and of lymphocyte homing to peripheral lymph nodes. Its cleavage indicates cellular activation. CD62L expression also helps distinguish leukocyte subsets (including certain neutrophil and monocyte populations) and is used clinically to assess immune cell trafficking and activation status in infections and inflammatory disease.

What is CD27 a marker for in T cells?plus

CD27 is a TNF-receptor family costimulatory molecule expressed on most naïve and central memory T cells; it promotes T cell survival, proliferation and differentiation after antigen encounter. Sustained CD27 expression marks less-differentiated, long-lived T cells, whereas loss of CD27 is associated with terminally differentiated effector or senescent T cells, helping distinguish memory/naïve versus effector phenotypes.

Can I take my diabetes medication before CD4 (Pan T Cell Marker)?plus

If you take insulin or diabetes tablets and are fasting for CD4 (Pan T Cell Marker), ask your doctor whether to delay the dose until after the sample is collected, to avoid a low-sugar episode.

Can CD4 (Pan T Cell Marker) be combined with a health package?plus

Yes. CD4 (Pan T Cell Marker) can be booked on its own or as part of a broader preventive health package on GetVisit, which often works out more cost-effective. You can choose either option before payment.
