Test Overview & Methodology
The Fluorescence In-Situ Hybridization (FISH) test for 22q11.2 deletion is a targeted molecular cytogenetic assay that identifies microdeletions on chromosome 22, confirming DiGeorge syndrome (velocardiofacial syndrome). This rapid, high-precision test supports early diagnosis and clinical intervention for affected infants and children in the UAE.

Patient FAQ & Clinical Guidance
1. What is the FISH test for 22q11.2 deletion used for?
This test detects microdeletions on chromosome 22q11.2 that cause DiGeorge syndrome (velocardiofacial syndrome) with 99.9% sensitivity in postnatal blood samples. It is primarily indicated for infants and children presenting with congenital heart defects, hypocalcemia, recurrent infections, or characteristic facial features. Early diagnosis enables timely intervention, family planning, and coordinated multidisciplinary care.
2. How should I prepare my child for the blood draw?
Ensure your child is hydrated and calm; no fasting is required. A green-top sodium heparin tube is used for sample collection. Our VIP Mobile Phlebotomy service will handle the collection at home under strict temperature-controlled cold-chain conditions. A properly filled Chromosome & FISH analysis Requisition Form (Form 17) is mandatory. Do not freeze the sample.
3. What does a positive result mean for my child's future health?
A positive result indicates a high probability of DiGeorge syndrome, confirming the 22q11.2 deletion. This may affect cardiac, immunological, endocrine, and cognitive development. A positive finding requires genetic counseling and a comprehensive care plan coordinated with pediatric cardiologists, immunologists, and developmental specialists. Our clinical team will support follow-up referrals and ongoing guidance.
