Anti-transglutaminase IgA Diagnostic Algorithm
Celiac Diagnostic Algorithm
Transglutaminase IgA Ab Algorithm
TTG IgA Algorithm
CMH Lab Section
3 mL red with gold ring (gel)
Initial testing in algorithm is batched. Testing is done Monday through Friday.
Turn Around Time
If level is: ≤7 mg/dL then: anti-deaminated Gliadin IgG
If level is: >7 mg/dL then: anti-tTG IgA. If the anti-tTG IgA is >20 then Endomysial Antibodies IgA.
Some testing in this algorithm is done as Sendout testing.
