1.0 mL serum in red top or serum separator OR 1.0 mL CSF in non-additive tube (label accordingly).
Test Description
Detection of the surface antigen proteins 2,4/3 in the serum or CSF.
This test identifies exposure to S. neurona and does not confirm active disease. There is no correlation with the level of the titer and the likelihood of disease. A serum to CSF titer ratio is recommended for more definitive diagnosis (see code S14390).
A negative test result makes EPM an unlikely cause of disease.
Note: If submitting BOTH serum and CSF use test code S14390 for the serum ELISA and serum to CSF ratio.
