Stool test codes

Traditional culture methods have been replaced by Real Time PCR for enteric pathogen testing. The benefits are increased sensitivity and a higher detection rate. Once received and processed in the microbiology laboratory, negative results will be available within 24 hours. Positive results will be followed up with culture and sensitivities for final reporting.
