Test Overview & Methodology
The HLA Single Antigen Bead Assay (DSA‑SAB) is the gold‑standard Luminex‑based test for detecting donor‑specific anti‑HLA Class I and II IgG antibodies to assess humoral alloreactivity pre‑ and post‑transplant. This highly sensitive assay quantifies mean fluorescence intensity (MFI) to guide immunosuppression and monitor antibody‑mediated rejection in kidney transplant recipients.
| Feature | Our Test (DSA‑SAB Luminex) | Closest Alternative (CDC Crossmatch / ELISA) |
|---|---|---|
| Methodology | Luminex X‑Map technology – fully quantitative | Complement‑dependent cytotoxicity (CDC) or semi‑quantitative ELISA |
| Specificity for DSA | High – identifies individual antigen specificities | Low to moderate; may miss low‑titre non‑cytotoxic antibodies |
| Clinical Sensitivity | >95% for detecting relevant DSA | 70–80% |
| Turnaround Time | 10–12 working days | 1–2 days (CDC) / 3–5 days (ELISA) |
Physician Insight & Safety Protocols
“As a general practitioner, I emphasise that this test is an important tool for transplant monitoring. While I coordinate your overall care, your nephrologist or transplant specialist will interpret these results. We ensure your sample is handled with the highest standards and provide compassionate guidance throughout the process.”
— Dr. Ajay Singh, DHA Registration ID: 36234132
Medication Warning
Do not discontinue prescribed immunosuppressive medication without consulting your doctor. Abrupt changes can trigger severe rejection episodes.
Exclusion Criteria & ER Red Flags
- Test may be postponed if: active systemic infection, recent vaccination (within 4 weeks), or recent IVIG/rituximab therapy that could interfere with bead assay.
- Emergency Red Flags – Seek immediate care if you experience: sudden drop in urine output, graft tenderness, fever, severe hypertension, or acute shortness of breath. These may indicate acute rejection or infection.
Patient FAQ & Clinical Guidance
1. What does the HLA Single Antigen Bead Assay detect?
This test detects and measures donor‑specific anti‑HLA Class I and II IgG antibodies to predict antibody‑mediated transplant rejection. It is used pre‑transplant to assess sensitization and post‑transplant to monitor the emergence of de novo DSA, enabling timely intervention.
2. How should I prepare for the HLA DSA‑SAB blood test?
Provide a brief clinical history; no fasting is required and you may continue prescribed immunosuppression unless your physician advises otherwise. The test requires only 2 mL of serum collected from one SST tube, shipped refrigerated. You will be asked to share your transplant date, donor specifics, and recent medication changes.
3. When will I receive my results and what do they mean?
Results are available within 10–12 working days; a positive DSA indicates increased risk of antibody‑mediated rejection. MFI values are reported with interpretive guidelines. Your transplant team will correlate the findings with clinical and biopsy data to decide on therapy adjustments. A negative result generally implies lower immunological risk.
