Celiac sprue - a cryptic disease: A case report

Table 1 Results from Epstein-Barr virus antibody profile

Name	Value	Reference range
EBV Ab VCA, IgM	81.6 H	0.0-35.9 (U/mL), Negative ≤ 36.0 U/mL, Equivocal = 36.0-43.9 U/mL, Positive ≥ 43.9 U/mL
EBV Ab VCA, IgG	225.0 H	0.0-17.9 (U/mL), Negative = 18.0 U/mL, Equivocal = 18.0-21.9 U/mL, Positive ≥ 21.9 U/mL
EBV Nuclear Antigen Ab, IgG	66.7 H	0.0-17.9 (U/mL), Negative ≤ 18.0 U/mL, Equivocal = 18.0-21.9 U/mL, Positive ≥ 21.9 U/mL

EBV: Epstein-Barr virus.

Table 2 Results from celiac disease panel

Name	Value	Reference range
Endomysial antibody IgA	Positive	Negative
t-Transglutaminase (tTG1) IgA	> 100 H	0-3 (U/mL), Negative = 0-3 U/mL, Weak Positive = 4-10 U/mL, Positive ≥ 10 U/mL
Immunoglobulin A, Qn, serum	137 H	87-32 (mg/dL)

¹t-Transglutaminase has been identified as the endomysial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten sensitive enteropathy.
