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.
