Rapid PCR testing for skin & nail fungal infections now available You are here:HomeFor DoctorsDoctor Information Rapid and sensitive real-time PCR for detection of the most common cause of skin & nail fungal infections is now available at St Vincent's Pathology. PCR allows the time taken for the detection of infections to be reduced from 3-4 weeks to only a few days, allowing treatment to be started earlier. Microscopy will still be performed on all skin and nail samples. Note, some cultures will be required on the basis of the initial results. For more information, please contact the Department of Microbiology.
