Polymerase chain reaction for diagnosis of genital herpes: a missed opportunity?
This study audited the utilization of herpes simplex virus polymerase chain reaction (HSV PCR) in the investigation of recurrent anogenital ulceration at the Mortimer Market Centre. Clinic guidelines for use of HSV PCR were modified in April 2003 to expand PCR use. Ninety-six case-notes belonging to patients presenting with recurrent anogenital ulceration between 1 April and 16 October 2003 were reviewed and 59 were suitable for inclusion. Details of the investigations carried out at each visit were recorded. HSV PCR was used according to guidelines in eight of the 59 cases studied. This audit showed under-utilization of HSV PCR testing with poor adherence to clinic guidelines when cases of suspected recurrent genital herpes were investigated. This led to under-diagnosis and delay in diagnosis. This audit stresses the importance of informing all clinical staff of the improved sensitivity and relative affordability of HSV PCR compared with HSV tissue culture.
