Parainfluenza PCR Panel

The UW Clinical Virology Laboratory in the Department of Laboratory Medicine and Pathology incorporates the modified FDA approved Panther Fusion® assay for the detection and differentiation of Human parainfluenza viruses type 1, type 2 , type 3 and type 4 using real-time PCR.

The assays targets the hemagglutinin neuraminidase gene for each virus. Results are reported as Detected or NOT detected and a semi-qualitative result is provided by reporting the PCR Cycle threshold (Ct) value for positive specimens.




Real-time Polymerase Chain Reaction.

Ordering & Collection

Specimen Type
Nasopharyngeal swab, Oropharyngeal swab, Anterior Nares swab, Broncho alveolar lavage (BAL) and tracheal aspirate.

Collect swab specimens according to standard technique using a polyester-, rayon-, or nylon-tipped swab. Immediately place the swab specimen into VTM/UTM. Do not use calcium alginate swabs. Refrigerate (2-8°C) within 4 hours of collection.

Collect Broncho alveolar lavage (BAL) and tracheal aspirates in a sterile container.

Minimum sample requirement: 0.75 mL

Handling Instructions

Transport specimens on ice (ice Pak), store at 2 to 8°C for up to 72 hours post collection. If there is a greater than 72 hours delay before testing of the specimen, freeze at -70°C or colder and ship on dry ice. Do not freeze/thaw.

requested: 1 mL
minimum: 750 µl



Send sample to UW Virology Laboratory within 4 hours of collection. If sample cannot arrive within 4 hours of collection, store sample at 2-8°C (ice pack) for up to 72 hours of collection. If there is a greater than 72 hour delay before testing sample, freeze sample at -70°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Samples stored at 2-8°C greater than 72 hours old may be rejected. Do not freeze/thaw.
