Specimen(s):
Plasma
Collection Medium:
![]() |
Plasma Separator Tube 4.5 mL |
Minimum:
Adult - 3 mL plasma separator tube
Pediatric - two Microtainer® devices
Pediatric - two Microtainer® devices
Turn Around Time:
3 hours (upon receipt in laboratory)
Reference Range:
Gliadin (Deamidated) IgA: Negative: <15 U/mL Positive: 15 U/mL or greater The deamidated gliadin (DPG) IgA reflexes automatically to DPG IgG if the total IgA is too low. In these cases, DPG IgA will be resulted as "LOW IGA" and the charges credited. Tissue Transglutaminase IgA: Negative: <15 U/mL Positive: 15 U/mL or greater The tissue transglutaminase (TTG) IgA reflexes automatically to TTG IgG if the total IgA is too low. In these cases, TTG IgA will be resulted as "LOW IGA" and the charges credited.
Comments:
Methodology:
Gliadin IgA, Gliadin IgG, Tissue Transglutaminase IgA, and Tissue Transglutaminase IgG: Multiplex Flow Immunoassay
Sample Processing:
Centrifuge at a speed and time necessary to get barrier separation of plasma/serum and cells within 1 hour of collection. Send specimen in original tube. Do Not transfer to another tube.
Each sample must be labeled with at least TWO full patient identifiers (First/Last Name & DOB are sufficient for non-UIHC affiliated clients) to avoid sample rejection/delays.
