Sometimes an individual may receive a different test result when they get tested at another testing provider e.g. someone receives a positive gonorrhoea test at SHL but then tests negative for gonorrhoea when they attend a sexual health clinic in person. These are called discordant results. Discordant results can be due to a number of reasons which are detailed below. If you are concerned about receiving a discordant result or are unsure whether you should receive treatment or not, please contact the clinical team at SHL on 020 8191 0222.
