Overview
The HLA Single Antigen Bead Assay for Class I IgG antibodies (also known as DSA-SAB Class I) detects donor-specific antibodies directed against HLA‑A, ‑B, and ‑C antigens. It is an essential tool in kidney transplantation for immunological risk stratification, post‑transplant monitoring, and guiding immunosuppressive therapy.
| Feature | Our Test (DSA-SAB Class I) | Closest Alternative (CDC Crossmatch) |
|---|---|---|
| Methodology | Luminex xMAP® technology (multiplex bead‑based) | Complement‑dependent cytotoxicity (CDC) |
| Sensitivity | 99.9% (single antigen resolution) | ~70‑80% (cell‑based, limited resolution) |
| Turnaround Time | 10–12 days | 2–3 hours (but not quantitative) |
| Clinical Value | Pre‑transplant risk, post‑transplant DSA monitoring, virtual crossmatch | Basic histocompatibility, not donor‑specific |
Physician Insight & Safety Protocol
Dr. PRABHAKAR REDDY (DHA License: 61713011, Senior Consultant Nephrologist) states: "This assay provides a refined immunological fingerprint; however, a positive DSA must always be correlated with graft function and biopsy findings. A negative result does not exclude all forms of immune injury. Our team is here to support you with compassionate, evidence‑based guidance throughout your transplant journey."
⚠ Medication Safety Warning
Do not discontinue prescribed immunosuppressive medication without consulting your transplant physician. Any change may trigger acute rejection.
💉 Exclusion Criteria & ER Red Flags
- Active systemic infection or acute illness – reschedule test after recovery.
- Recent vaccination (especially live vaccines) within 2–4 weeks.
- Severe hemodilution or unlabeled sample – recollection required.
- Emergency symptoms: sudden pain over graft site, fever >38.5°C, anuria, or shortness of breath – seek immediate medical attention.
Patient FAQ & Clinical Guidance
1. What is the purpose of this test?
Direct Answer: It detects donor-specific IgG antibodies to assess immunological risk before or after solid organ transplantation. The single antigen bead technology identifies exactly which HLA Class I molecules are targeted, enabling precise risk stratification and tailored immunosuppression.
١. ما الغرض من هذا الفحص؟
يكتشف الأجسام المضادة IgG الخاصة بالمتبرع لتقييم الخطر المناعي قبل زراعة الأعضاء الصلبة أو بعدها. تتيح تقنية الكريات أحادية المستضد تحديدًا دقيقًا لجزيئات HLA class I المستهدفة، مما يُوجّه العلاج المثبط للمناعة.
2. How is the sample collected?
Direct Answer: A dedicated home phlebotomy service collects blood under strict cold‑chain protocols, guaranteeing absolute sample integrity. A certified professional draws 2 mL serum (1 mL minimum) in a gel tube; the specimen is refrigerated or frozen during transport to our ISO‑certified lab.
٢. كيف يتم جمع العينة؟
يقوم خدمة الفصد المنزلية المخصصة بجمع الدم وفق بروتوكولات سلسلة تبريد صارمة، مما يضمن سلامة العينة المطلقة. يُسحب 2 مل (الحد الأدنى 1 مل) في أنبوب جل، وتُنقل العينة مبردة أو مجمدة إلى مختبرنا المعتمد ISO.
3. What do positive results mean?
Direct Answer: Positive DSA indicates potential risk for antibody‑mediated rejection, requiring urgent nephrologist consultation for immediate management. The report includes fluorescence intensity (MFI) values, which must be interpreted alongside clinical status and biopsy findings by your transplant team.
٣. ماذا تعني النتائج الإيجابية؟
تشير الأجسام المضادة الخاصة بالمتبرع إلى خطر محتمل لرفض مناعي بوساطة الأجسام المضادة، مما يتطلب استشارة عاجلة من طبيب الكلى لإدارة فورية. يشتمل التقرير على قيم شدة التألق (MFI) ويجب تفسيرها مع الحالة السريرية ونتائج الخزعة من قبل فريق الزراعة.
