For performing urine cultures using culturette swabs, please do NOT fill the culturette tube with urine as the tubes invariably leak urine everywhere. Instead, dip the culturette swab into the urine specimen and then place the urine swab back into the culturette tube.

Note: With the heartworm season approaching, please remember the preferred specimen for heartworm testing is a Red Top tube. Lavender Top tubes can cause false positives.
