Peter L. Warren's question:
 
"Does anyone know the range for positive and negative test results for
endomysial IgA ?"
 
        We are using different dilutions of patient serum and incubate them
with tissue slides. Generally, a fluorescence  at the dilution of  1:4
or 1:5  is considered as borderline positive. Any fluorescence in the
tissue above this  dilution indicates a real positive result. Most of
our patients with CD or DH  have a value higher than 1:32.
