1.0 mL serum in red top, white top, or serum separator tube OR 1.0 mL CSF in red top tube. Label sample accordingly.
Test Description
Detection of the surface antigen proteins 2,4/3 in the serum or Cerebrospinal Fluid (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.
