Stool in a sterile, leak-proof container
2 to 4 ml of liquid stool; 2 to 4 grams of formed stool
2 ml of liquid stool; 2 grams of formed stool
Keep specimen at 4C
The specimen of choice is stool. Rectal swabs are inferior to stool specimens for the detection of viruses and are discouraged. If it is necessary to collect a rectal swab, a sufficient quantity of fecal material (at least a pea-sized amount) should be obtained. If fecal material is not clearly visible on the swab, the specimen is most likely inadequate. Rectal swabs should be immediately placed in viral transport medium. Specimens should be transported to the laboratory as quickly as possible after collection. When immediate transport is not possible, refrigerate the specimens or keep them on wet ice. For delays of more than 24-48 hours (e.g., when shipping specimens from an outside facility), specimens should be processed as needed and rapidly frozen to -70C and then transported to the laboratory on dry ice.
Specimens for molecular testing should not be stored at room temperature or frozen at -20C. This is critical to ensure the stability and amplification of nucleic acids, particularly for the detection of RNA viruses since RNA is unstable and easily degraded by RNAses from the surrounding environment.
Amplification and detection of parechovirus RNA from the highly conserved 5'-untranslated region of the genome using TaqMan real-time PCR technology. This test is performed pursuant to an agreement with Roche Molecular Systems, Inc.
If positive, results are reported as parechovirus RNA detected.
Negative or no parechovirus RNA detected
