Special Info
Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of acute specimens. Label specimens plainly as 'acute' or 'convalescent.' Plasma or cerebrospinal fluid (CSF) are unacceptable. Contaminated, hemolyzed, or severely lipemic specimens will be rejected. This test is New York DOH approved.
Clinical Info
This test detects neutralizing antibodies to echovirus types 6, 7, 9, 11, and 30. Single positive antibody titers of > or = 1:80 may indicate past or current infection. Seroconversion or an increase in titers between acute and convalescent sera of at least fourfold is considered strong evidence of current or recent infection.
