Parainfluenza Virus Type 1 Antibodies, IgG, Serum

See Also Parainfluenza Virus Type 1 Antibodies, IgG, Serum

Due to respiratory viral pathogens causing very similar clinical symptoms, differential diagnosis of the pathogens is required. The detection of PIV-specific IgG antibodies is suggestive of past or recent infection with PIV. However, cross-reactivity between PIV types is possible. A fourfold rise or drop in titre is generally thought to signify acute infection if the testing is performed at the same time on paired acute- and convalescent-phase serum samples.
