Frequently Asked Questions
Is fasting required for tTG-IgG test?
No, fasting is not required. The test can be performed on a non-fasting sample.
What does a positive tTG-IgG result mean?
Elevated IgG antibodies against tissue transglutaminase suggest celiac disease, especially in patients with IgA deficiency or atypical presentations.
How is the sample collected?
A venous blood sample of approximately 1 mL is collected in a serum separator tube.
Can medications affect the result?
Immunosuppressants or recent gluten withdrawal may alter antibody levels. Inform your doctor about all current medications.
What is the typical turnaround time?
Reports are usually available within 24–48 hours at Dr. Patho Labs & Diagnostics, Chhatrapati Sambhajinagar.
Does stress influence celiac antibody levels?
Psychological stress does not directly affect tTG-IgG levels, but chronic illness and nutritional status may impact overall immune response.
