Tests are not performed until the convalescent specimen is received for simultaneous assay, except for possible Western or Saint Louis Equine Encephalitis during the summer-fall encephalitis season, when IgM antibody will be sought in the initial specimen, or where immune status is being assessed [see Rabies Antibody (Neutralizing)-response to vaccine, Rubella Antibody and Varicella-zoster Antibody (specify for immune status). Also see table "Viral Serology: Interpretation of Test Results" following the table "Viral Culture: Specimen Collection ...".
Aseptic Meningitis & Encephalitis Group:
Usually includes CF Antibody testing for Herpes simplex, Mumps, Measles and Rubella (in childhood) and Adenovirus (in patients under 18). Requests for LCM, Poliovirus or Arbovirus titers must be accompanied by appropriate history and are forwarded to State Laboratory. IF ARBOVIRUS INFECTION IS SUSPECTED DURING THE SUMMER-FALL ENCEPHALITIS SEASON, SUBMIT THE FIRST SPECIMEN WITHOUT DELAY FOR TESTS TO DETECT IgM ANTIBODY, even though the convalescent serum has not yet been received.
Exanthem Group: Usually includes antibody testing for Herpes simplex, Measles, Mumps and Varicella-zoster.
Respiratory Group: Usually includes antibody tests to Adenovirus, Influenza A and B (in season), Mycoplasma pneumoniae, Parainfluenza 1-3 (in children under 3) and Respiratory syncytial virus (in patients under 18).
