Diagnostic Tests for Parainfluenza
Tests and diagnosis discussion for Parainfluenza:
Infection with HPIVs can be confirmed in two ways: 1) by isolation and
identification of the virus in cell culture or by direct detection of
the virus in respiratory secretions (usually, collected within one week
of onset of symptoms) using immunofluorescence, enzyme immunoassay, or
polymerase chin reaction assay, and 2) by demonstration of a significant
rise in specific IgG antibodies between appropriately collected paried
serum specimens or specific IgM antibodies in a single serum specimen.
