This can be best differentiated with a simple vaginal swab culture. A vaginal swab test is a test done by taking samples of secretions in the vagina with a device that looks similar to a cotton bud. With the secretions attached, the swab is then sent to a laboratory for further analysis.
The majority of the infectious disease conditions can be diagnosed with a high vaginal swab, which is then sent for microbiology evaluation. STDs like gonorrhoea and chlamydia may also be diagnosed with an STD DNA PCR test, also following a vaginal swab. For more information, please see your friendly gynaecologist or STD specialist.
