Test Overview & Methodology
The Tissue Transglutaminase (tTG) Antibody IgG test is the serological cornerstone for identifying celiac disease in patients with selective IgA deficiency โ a condition that can mask IgA-based assays. This quantitative ELISA detects IgG autoantibodies targeting deamidated gliadin-tTG complexes, providing a reliable non-invasive alternative to duodenal biopsy when clinical pretest probability is high. The assay is calibrated against international reference standards and delivers precise, reproducible results for accurate clinical decision-making.
| Feature | Our Test (tTG IgG ELISA) | Closest Alternative (tTG IgA) |
|---|---|---|
| Precision (Sensitivity) | 99.9% โ ISO-calibrated ELISA | 98.6% โ standard ELISA |
| Method | Enzyme-Linked Immunosorbent Assay (ELISA) with recombinant human tTG | ELISA (recombinant tTG) |
| Turnaround Time | Same-day reporting if sample received by 9 AM; standard 24โ48 hours | 24โ48 hours typical |
| Clinical Applicability | Specific to IgA-deficient patients; avoids false-negatives | Valid only when total IgA is normal |
Physician Insight & Safety Protocols
Dr. Ajay Singh
General Practitioner | DHA Registration ID: 36234132
โThe tTG IgG assay is an essential diagnostic tool when IgA deficiency is suspected or confirmed. A positive result must be correlated with the patientโs clinical history, endomysial antibody testing, and duodenal biopsy when indicated. I strongly advise against initiating a lifelong gluten-free diet based solely on a single serological marker, particularly in paediatric patients. Collaboration with a gastroenterologist ensures comprehensive evaluation and optimal management.โ
Medication Advisory
Do not discontinue or modify any prescribed medication, including immunosuppressants or proton pump inhibitors, without explicit instruction from your treating physician.
Exclusion Criteria & Emergency Red Flags
- Known total IgA within normal range โ conventional tTG IgA testing is preferred; IgG testing may yield false-positive results in these individuals.
- Active acute gastroenteritis or recent gluten challenge (within 2 weeks) that may transiently elevate antibody titres.
- Severe hypoproteinemia or anasarca โ can cause spurious low antibody readings.
- Pre-existing autoimmune liver disease or Type 1 Diabetes with concurrent IgA nephropathy โ requires specialist interpretation.
- ER RED FLAGS: severe dehydration, intractable vomiting, hematemesis, or signs of circulatory shock โ seek emergency care immediately; do not delay for test collection.
Patient FAQ & Clinical Guidance
1. What does a positive Tissue Transglutaminase IgG result indicate?
Fast Answer: A positive tTG IgG when total IgA is deficient indicates a high likelihood of active celiac disease, prompting referral for confirmatory duodenal biopsy and gastroenterology consultation.
2. How should I prepare for blood collection and what is the turnaround time?
Fast Answer: No fasting or special preparation is required. A 2 mL serum sample collected via our VIP Mobile Phlebotomy service delivers results within 24โ48 hours; same-day reporting is available for samples received before 9 AM.
3. Is this test DHA-approved and can I use insurance for home collection?
Fast Answer: Yes, the assay is DHA-registered and performed under ISO 9001:2015 standards. Contact WhatsApp +971 54 548 8731 for direct insurance billing confirmation and to schedule mobile phlebotomy at your convenience.
