SPECIMEN COLLECTION AND HANDLING
Fresh urine does not require any pretreatment. A fresh urine sample should be collected in the container provided. Alternatively, a clean dry
plastic or glass container may be used for specimen collection. If the specimen is not immediately tested after the specimen collection, the
specimen may be refrigerated at 2-8°C for up to 2 days or frozen at -20°C for longer period of time. Specimens that have been refrigerated must
be equilibrated to room temperature prior to testing. Frozen specimens must be thawed and mixed thoroughly prior to testing.
