Test Overview & Methodology
The HLA Single Antigen Bead Assay for Class II IgG Antibodies (DSA‑SAB Class II) is a high‑resolution multiplex immunoassay that identifies and quantifies donor‑specific IgG antibodies directed against human leukocyte antigen Class II loci. It is essential for pre‑transplant risk stratification and post‑transplant monitoring of antibody‑mediated rejection. The test uses Luminex X‑Map fluorescence technology to provide quantitative mean fluorescence intensity (MFI) values for each Class II allele.
| Feature | Our Test (Luminex DSA Class II) | Closest Alternative (CDC Crossmatch) |
|---|---|---|
| Precision | Single antigen resolution, quantitative MFI | Qualitative, whole‑cell lysis |
| Method | Luminex X‑Map fluorescence | Complement‑dependent cytotoxicity |
| Speed | 10–12 days | 2–3 days (but lower clinical utility) |
Physician Insight & Safety Protocols
Medication Advisory
Do not discontinue or modify any immunosuppressive or prescribed medication without explicit instruction from your transplant physician.
Safety Exclusion Criteria & Red Flags
- Recent IVIG or rituximab therapy (within 4 weeks) may interfere with results; defer testing unless directed by a transplant specialist.
- Active systemic infection or acute illness at the time of sample collection.
- ER Red Flags: Sudden graft pain, fever >38.5°C, oliguria (kidney), dyspnea (heart/lung), or new‑onset organ dysfunction – seek immediate emergency care.
- Pediatric or minor patients: sample collection must comply with Federal Law No. 2 of 2019 concerning guardian consent for health information and procedures.
Patient FAQ & Clinical Guidance
1. What is the HLA Single Antigen Bead Assay for Class II IgG Antibodies?
It is a highly sensitive blood test that detects donor‑specific IgG antibodies against HLA Class II antigens to assess transplant rejection risk. These antibodies can attack the transplanted organ, and quantification helps doctors adjust immunosuppression before clinical damage occurs.
2. How is the sample collected and what preparation is needed?
A small blood sample (2 mL) is drawn from a vein using a serum separator tube. No fasting is required. Our VIP mobile phlebotomist arrives at your home or office; the sample is immediately refrigerated and transported under validated cold‑chain conditions to the ISO‑certified lab.
3. What does a positive result mean for my transplant?
A positive result indicates the presence of donor‑specific HLA Class II antibodies, which increases the risk of antibody‑mediated rejection. It does not confirm rejection by itself; your transplant team will integrate this finding with biopsy and functional tests to decide on enhanced immunosuppression or intervention.
