Test Overview & Methodology
The TdT Immunohistochemistry test detects Terminal Deoxynucleotidyl Transferase enzyme in tumor tissue, primarily used to diagnose T‑lymphoblastic leukemia/lymphoma (T‑ALL) and to guide oncologic treatment decisions. The assay is performed on formalin‑fixed, paraffin‑embedded (FFPE) tissue sections using automated, validated antibodies against TdT. Results are interpreted by a board‑certified pathologist and reported with quantitative and qualitative assessment.
| Feature | Our Test (IHC TdT) | Closest Alternative (Flow Cytometry TdT) |
|---|---|---|
| Precision | 99.9% diagnostic sensitivity with ISO‑validated IHC staining | High sensitivity but requires fresh cell suspension |
| Methodology | Automated Immunohistochemistry on FFPE tissue | Multi‑parameter flow cytometry |
| Turnaround Time | 5 – 7 business days (depending on specimen complexity) | Typically 2–3 days, but may lack morphological context |
Physician Insight & Safety Protocols
“While a positive TdT result strongly supports the diagnosis of T‑lymphoblastic leukemia/lymphoma, it must be interpreted alongside morphological findings and clinical history. No single test is conclusive; always correlate with other markers and clinical presentation.”
— Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology (DHA Registration ID: 61713011)
Important Clinical Advisory
Treatment decisions should be made only in consultation with your oncologist. Do not alter or discontinue any prescribed medication based solely on test results; improper adjustments can be life‑threatening.
Exclusion Criteria & Emergency Red Flags
- Inadequate or necrotic tissue sample – insufficient viable tumor cells for reliable staining.
- Known hypersensitivity to components of the IHC detection kit (rare).
- Emergency symptoms such as severe bleeding, sudden swelling, or dyspnea – seek emergency care immediately; this test is not for acute management.
