26054 Parvovirus B19, PCR, Plasma (PARVP)

Parvovirus B19, PCR, Plasma (PARVP)
Test Code: PARVPSO
Synonyms/Keywords
​​B19, Erythrovirus B19, Fifth Disease-Parvovirus, Human Parvovirus B19, Parvovirus B19 PCR, Parvovirus PCR, Parvovirus-Fifth Disease
Useful For
Diagnosing parvovirus B19 infection in plasma specimens
Specimen Requirements
Fasting Required Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
​No ​Plasma ​EDTA Lavender Top Tube (LTT) ​ ​0.5 mL ​0.3 mL ​
Specimen Stability Information
Specimen Type Temperature Time
​Plasma EDTA ​ ​Refrigerate (preferred) ​7 days
​Frozen ​7 days
Rejection Criteria
Gross Hemolysis
Interference
A negative result does not necessarily indicate the absence of parvovirus B19 infection. False-negative results may be due to the virus being present at levels below the limit of detection for this assay, or to inhibitory substances that may be present in the specimen.
 
This assay has only been validated for the detection of genotype 1 parvovirus B19 and its ability to detect the less common genotypes 2 and 3 is unknown.

Interpretation
​A positive result indicates that parvovirus B19 DNA is present in the clinical sample. However, a positive result does not differentiate between actively replicating virus, transient infection that may be asymptomatic, or simply the presence of remnant viral nucleic acid.
 
A negative result suggests the absence of parvovirus B19 infection.
