Test Overview & Methodology
This test quantifies donor‑recipient chimerism after bone marrow transplant using Variable Number Tandem Repeat (VNTR) analysis by End‑Point PCR. It detects the proportion of donor vs. recipient DNA in peripheral blood, enabling precise monitoring of engraftment, early detection of graft failure, and molecular relapse assessment.
| Feature | Our Test (VNTR Chimerism – End‑Point PCR) | Closest Alternative (STR Analysis by Capillary Electrophoresis) |
|---|---|---|
| Precision | 99.9% diagnostic sensitivity; validated VNTR loci with high heterozygosity | Standard STR multiplex; lower informativeness in certain populations |
| Methodology | Endpoint PCR with proprietary ISO‑calibrated detection | PCR + capillary electrophoresis; fewer robust loci for post-BMT monitoring |
| Turnaround Time | 3–4 working days (express option available) | 5–7 working days on average |
Physician Insight & Safety Protocols
“As a medical geneticist, I emphasise that VNTR chimerism results must always be integrated with the patient’s full clinical picture – including immunosuppression history, blood counts, and donor‑specific antibodies. A rising recipient DNA fraction can herald graft failure or relapse; serial monitoring is therefore essential. Never modify immunosuppressive therapy without comprehensive clinical evaluation.”
— Lina Osama Zaki Quteineh, Consultant Medical Genetics (DHA: 9294403)
Advisory: Pre‑Collection Precautions
This test requires a valid doctor’s prescription. Do not discontinue any prescribed immunosuppressive, corticosteroid, or antimicrobial therapy prior to sample collection unless explicitly directed by your transplant physician. If you experience fever, severe bruising, uncontrolled bleeding, or signs of acute graft‑versus‑host disease (skin rash, diarrhea, jaundice), seek immediate medical attention – do not wait for test results.
Exclusion: Patient Eligibility & Consent
Patients under 18 years require guardian consent in accordance with Federal Decree‑Law No. 4 of 2016 on Medical Liability. This test is not intended for use as a sole basis for clinical decisions; it must be interpreted by a qualified physician. Home collection is not available for patients requiring strict clinical supervision – hospital extraction only for such cases.
Patient FAQ & Clinical Guidance
1. How does the VNTR Chimerism test detect graft failure earlier than blood counts?
Our endpoint PCR directly quantifies donor DNA fraction weeks before hematologic changes appear, providing a molecular early warning for intervention.
2. Can I have the sample collected at home, and is it stable during transport?
Yes, our VIP mobile phlebotomy team collects whole blood in special EDTA tubes and transports it in a 2–8°C cold chain, ensuring DNA integrity for up to 48 hours.
3. How do you protect my genetic data under UAE privacy laws?
All DNA data is encrypted, stored on UAE‑based servers, and handled strictly per Federal Decree‑Law No. 45 of 2021 on Personal Data Protection (PDPL) and Federal Law No. 2 of 2019 Concerning the Use of Information and Communication Technology in Health Fields, with no third‑party sharing.
