Test Overview & Methodology

The Tissue Transglutaminase (tTG) and Deamidated Gliadin Peptide (DGP) Screen Test is a high-sensitivity serological panel used to diagnose celiac disease (gluten-sensitive enteropathy) by detecting IgA and IgG antibodies. This combined approach minimises false negatives in IgA deficiency and provides superior diagnostic accuracy compared to tTG IgA alone.

Feature	Our Test (tTG-DGP Screen)	Closest Alternative (tTG IgA Only)
Precision	99.9% sensitivity; combined IgA/IgG minimizes IgA-deficiency false negatives	85-95% sensitivity; false negatives common in IgA deficiency
Methodology	Enzyme Immunoassay (ELISA) – DHA/MOHAP Standardized	ELISA or FEIA – may lack DGP component
Speed	Same-day report (sample by 9 am)	2–5 business days

Physician Insight & Safety Protocols

Dr. Ajay Singh – General Practitioner (DHA Registration ID: 36234132)

“Serological screening for celiac disease using tTG and DGP antibodies is a reliable first-line test. However, a positive result must be interpreted in the context of the patient’s gluten intake and confirmed with endoscopic biopsy. Patients should continue their normal gluten-containing diet until testing is complete and should never discontinue prescribed medications without medical supervision.”

⚠️ Advisory – Medication Guidance

Do not discontinue any prescribed medication or start a gluten-free diet prior to testing without consulting your doctor. Such actions may lead to false-negative results and delay diagnosis.

Exclusion Criteria & Emergency Red Flags

Exclusion: Known IgA deficiency (risk of false negative); strict gluten-free diet for >4 weeks without gluten challenge.
Red Flags – Seek Immediate Medical Attention: Severe abdominal pain, persistent vomiting, bloody stools, or signs of anaphylaxis.
Not intended for: Monitoring of dietary compliance alone; confirmatory biopsy is required for definitive diagnosis.
This test is suitable for adults and children under paediatric gastroenterologist supervision.

Patient FAQ & Clinical Guidance

1. What exactly does the Tissue Transglutaminase tTG-DGP Screen Test detect?

The test simultaneously measures IgA and IgG antibodies against tissue transglutaminase and deamidated gliadin peptide, the serological hallmarks of celiac disease autoimmunity.

2. How should I prepare, and must I keep eating gluten before the blood draw?

No special preparation is required, but you must continue consuming gluten-containing foods for at least 6 weeks prior to testing to avoid false-negative results.

3. When will I receive my results and what do they mean clinically?

Samples collected by 9 am are reported the same day, providing rapid diagnostic clarity. Elevated antibodies strongly suggest active celiac disease, but a gastroenterologist must correlate with your symptoms and biopsy findings.
