Test Overview & Methodology
Comprehensive Overview
This test uses multi-parameter fluorescent flow cytometry to detect nuclear TdT expression on haematopoietic cells, distinguishing immature lymphoid precursors from mature lymphomas and myeloid blasts. The assay is an essential component of the WHO/ICC classification algorithm for acute leukaemias and lymphoblastic neoplasms.
| Parameter | Our TdT Flow Cytometry | Standard Immunophenotyping Panel |
|---|---|---|
| Precision & Markers | 10‑colour, includes nuclear TdT, CD34, CD19, CD3, MPO as standard | 4–6 colour, often omits TdT, requiring reflex testing |
| Methodology | BD FACSCanto™ II / Beckman Coulter Navios with validated algorithms | First‑generation flow cytometers, manual gating |
| Turnaround Time | Same day (sample received by 9 AM) | 3–5 working days |
| Price (AED) | 450 | 300–400 (often incomplete) |
| Sample Collection | Hospital extraction (strictly accredited facility) | Variable, often delayed |
Physician Insight & Safety Protocols
“As your DHA-licensed specialist in diagnostic radiology, I want you to know that while this test provides a critical piece of the puzzle, it is not a stand‑alone verdict. The TdT result must be woven together with complete blood counts, bone marrow morphology, and molecular studies. I am here to walk you through what these numbers actually mean for you or your child.”
— Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology, DHA ID: 61713011
Patient Exclusion Criteria & Emergency Red Flags
- This test is not indicated for general cancer screening – only for patients with a strong clinical suspicion of acute leukaemia/lymphoma confirmed by a haematologist.
- Active severe infection or haemodynamic instability requires clinical stabilisation before sample collection.
- If the patient experiences any of the following, seek immediate ER care: uncontrolled bleeding, sudden confusion, chest pain, difficulty breathing, or high fever unresponsive to antipyretics.
- Minors must be accompanied by a legal guardian and provide consent as per UAE medical liability regulations.
- Bone marrow aspiration is an invasive procedure; absolute contraindications include severe coagulopathy (INR >1.5, platelets <20×10⁹/L) without haematologist clearance.
Patient FAQ & Clinical Guidance
1. What exactly is the TdT immunophenotyping test, and why is it ordered?
This flow cytometry test measures the nuclear enzyme TdT in blood or bone marrow to identify immature lymphoid cells. It is the gold standard for distinguishing acute lymphoblastic leukaemia/lymphoblastic lymphoma from mature B‑ or T‑cell malignancies, directly guiding chemotherapy selection. Clinicians order this when a patient presents with unexplained cytopenias, blasts on peripheral smear, or lymphadenopathy suspicious for a haematological cancer.
2. How is the sample collected, and where does it take place?
Sample collection is performed strictly within an accredited hospital facility. A trained phlebotomist collects 3 mL of peripheral blood in EDTA and heparin tubes or performs a bone marrow aspiration under local anaesthesia. Hospital extraction only – mobile home phlebotomy is disabled for safety. Temperature-controlled cold-chain transport at 18–22°C ensures sample integrity. You can schedule via WhatsApp at +971 54 548 8731.
3. How soon will I receive my results, and what do they mean?
Your report is delivered the same day if the sample reaches our lab by 9 AM, with a comprehensive interpretation of TdT positivity percentage and immunophenotype. A positive TdT (usually >10% of gated cells) strongly supports a precursor lymphoid neoplasm; absence favours mature leukaemia/lymphoma. Results are never diagnostic in isolation – your haematologist will integrate them with cytogenetics, FISH, and molecular markers to formulate the final diagnosis. We provide a free teleconsultation to help you understand the report.
