COLLECTION PROCEDURES

The following procedures are for patient-collect specimens and can be collected at home by the patient, with the exception of collection of a urine specimen from a catheter which requires the Collectors assistance and drug screening tests which require supervision by the Collector. Please indicate on request if urine is from an indwelling catheter.
