Unacceptable Conditions: Plasma.

Stability (collection to initiation of testing): Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Reference Interval:
Echovirus 6:  Less than 1:10
Echovirus 7:  Less than 1:10
Echovirus 9:  Less than 1:10
Echovirus 11: Less than 1:10
Echovirus 30: Less than 1:10
Interpretive Data: Single positive antibody titers of greater than or equal to 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.
