What is a CD45 / LCA (Leukocyte Common Antigen) Test in Delhi ?

What is CD45 / LCA (Leukocyte Common Antigen)?

This test measures the CD45 protein, also called leukocyte common antigen, which sits on most white blood cells. CD45 helps identify cells that come from the immune system. Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.

What does CD45 / LCA (Leukocyte Common Antigen) measure?

It is important because it separates immune cells from non-immune tissue under the microscope. Doctors use CD45 staining to detect and classify lymphomas and leukemias. It also helps tell whether a tumour is made of immune cells or has spread from another organ. The test can be done on biopsy tissue or blood by pathologists and lab teams.

What symptoms suggest CD45 / LCA (Leukocyte Common Antigen) may be needed?

A doctor may recommend CD45 / LCA (Leukocyte Common Antigen) when a patient reports unexplained weight loss, persistent fatigue, a lump under the skin, changes in bowel or bladder habits, unexplained pain, abnormal bleeding, persistent cough, or difficulty swallowing. Sample collection for Delhi is available at labs and at home across Mayur Vihar, Lajpat Nagar, and surrounding neighbourhoods.

How is CD45 / LCA (Leukocyte Common Antigen) performed?

This test is performed on a swab or fluid sample collected by a trained healthcare professional, not on a routine blood draw. Collection is quick and done at a GetVisit-partnered lab or collection point in Mayur Vihar or Lajpat Nagar, Delhi, after which the sample is dispatched to the NABL-accredited lab for processing.

How accurate is CD45 / LCA (Leukocyte Common Antigen)?

Samples collected in Mayur Vihar or Lajpat Nagar, Delhi are processed at NABL-accredited labs using validated methods and internal quality control. Accuracy depends on correct collection technique by a trained professional, which GetVisit's partnered centres follow. Reports are accepted by hospitals, specialists, and insurers across India.

Are there any risks to CD45 / LCA (Leukocyte Common Antigen)?

Risk is minimal. Swab, sputum, or fluid collection by a trained professional in Mayur Vihar or Lajpat Nagar, Delhi may cause brief, mild discomfort but no lasting effects. Any specific precaution for your test will be explained at the collection centre.

Did you know?

CD45 (leukocyte common antigen) is a transmembrane protein tyrosine phosphatase expressed on all nucleated hematopoietic cells.

CD45 / LCA (Leukocyte Common Antigen) Test Preparation in Delhi

Fasting and diet:

This test can be done at any time of day with no fasting. Keep to your usual meals and medicines, and drink water normally.

Medication:

Unless your physician advises a change, keep taking your usual prescriptions as normal.

What to bring:

Have your doctor's referral and photo ID ready; earlier reports for the same test are useful for tracking trends.

Timing and slots:

Book whenever is convenient; for fasting or hormone tests an early-morning slot is ideal. GetVisit covers Dwarka, Rajouri Garden, and all of Delhi.

CD45 / LCA (Leukocyte Common Antigen) Test Parameters in Delhi

Single standalone test:

CD45 / LCA (Leukocyte Common Antigen). Can be ordered individually or as part of a preventive health package on GetVisit.

Why Take a CD45 / LCA (Leukocyte Common Antigen) Test in Delhi ?

When does a doctor order CD45 / LCA (Leukocyte Common Antigen)?

CD45 / LCA (Leukocyte Common Antigen) is often included in immunohistochemistry and flow cytometry panels for suspected blood or lymphoid disease. Doctors may order it when there are swollen lymph nodes, unexplained masses, abnormal blood counts, or suspected lymphoma or leukemia.

Who should get CD45 / LCA (Leukocyte Common Antigen) 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 CD45 / LCA (Leukocyte Common Antigen) include higher-risk individuals in structured screening and patients already diagnosed who need trend monitoring. Results in Delhi should always be interpreted by an oncologist rather than in isolation.

What conditions can CD45 / LCA (Leukocyte Common Antigen) help diagnose?

It helps diagnose and monitor these cancers and distinguish them from metastatic tumours or inflammatory reactions. Abnormal results may come from cancers, infections, or immune disorders, and family history of blood cancers can make testing more important.

What do CD45 / LCA (Leukocyte Common Antigen) results mean?

Higher or positive results: A CD45‑positive result means the cells express CD45 (the leukocyte common antigen), indicating they are of hematopoietic/white‑blood‑cell origin. 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 CD45 / LCA (Leukocyte Common Antigen) be repeated?

For screening in higher-risk individuals: at the interval recommended for that specific cancer. For patients under treatment or in remission: on the schedule set by the oncologist, often every few months, to track the marker's trend rather than any single value.

What happens after CD45 / LCA (Leukocyte Common Antigen) results are ready?

Book a follow-up consultation after reviewing your results. GetVisit stores your reports alongside your previous test history, so your doctor sees your full health trend, not just today's snapshot. This longitudinal context significantly improves the clinical value of each repeat test.

What is CD45 leukocyte common antigen?plus

CD45 (leukocyte common antigen) is a transmembrane protein tyrosine phosphatase expressed on all nucleated hematopoietic cells. Encoded by PTPRC, it regulates antigen‑receptor signaling in T and B cells by modulating Src family kinases, influencing activation and development. Multiple isoforms (e.g. CD45RA, RO) arise from alternative splicing and serve as differentiation markers in flow cytometry and immunophenotyping.

Is LCA the same as CD45?plus

Yes. LCA (leukocyte common antigen) is the same as CD45 , a family of transmembrane protein tyrosine phosphatase isoforms expressed on nearly all nucleated hematopoietic (leukocyte) cells. CD45/LCA regulates antigen‑receptor signaling, exists in multiple isoforms, and is widely used as a pan‑leukocyte immunohistochemical marker to identify and classify hematologic cells and lymphoid malignancies.

Is CD45 a marker for lymphoma?plus

CD45 (leukocyte common antigen) is a pan‑leukocyte marker used to identify hematopoietic/lymphoid cells and aids lymphoma diagnosis. Most B‑ and T‑cell lymphomas express CD45, but expression may be reduced or absent in certain entities (for example classical Hodgkin lymphoma Reed–Sternberg cells and some plasma‑cell variants). Flow cytometry and immunohistochemistry use CD45 alongside other markers for accurate classification.

What does it mean when a CD45 marker is positive?plus

A CD45‑positive result means the cells express CD45 (the leukocyte common antigen), indicating they are of hematopoietic/white‑blood‑cell origin. It’s used in flow cytometry and immunohistochemistry to identify and classify leukocytes and to help distinguish lymphoid or myeloid malignancies from non‑hematopoietic tumors. Most leukocytes are CD45+, while mature red cells and platelets lack CD45.

Can I exercise before CD45 / LCA (Leukocyte Common Antigen)?plus

Avoid strenuous exercise for 12 to 24 hours before CD45 / LCA (Leukocyte Common Antigen), since intense activity can temporarily change several blood markers. Light everyday movement is fine.

Can CD45 / LCA (Leukocyte Common Antigen) be combined with a health package?plus

Yes. CD45 / LCA (Leukocyte Common Antigen) 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.
