91985: Endomysial IgG Antibody Screen and Titer Print View
Endomysial IgG IFA  Screen Negative   
Titer      

PRIMARY
1 Serum 2 (0.2) mL   Frozen - 30 Day(s)/Refrigerated - 14 Day(s)/Room Temperature - 48 Hour(s)  
ALTERNATE

Serological methods of detecting Immunoglobulin A (IgA) antibodies to gliadin, endomysium (EMA), reticulin, and tissue transglutaminase are routinely used for diagnosing both symptomatic and asymptomatic patients with Celiac Disease (CD). Since Immunoglubulin A (IgA) deficiency is 10 to 15 times more common in patients with Celiac Disease than in healthy subjects, IgG-specific antibody tests for endomysium are useful for the identification of IgA-deficient patients with CD.

Allow the blood to clot in an upright position for at least 30
minutes but not longer than 1 hour before centrifugation. Centrifuge
for at least 15 minutes at 2200-2500 RPM at room temperature within
one hour of collection, store at -20 deg celcius, and send 2 mL of
serum frozen in a plastic vial.
