Chlamydia
A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Nucleic acid amplification tests (NAATs) are the investigation of choice - highest sensitivity and specificity. Specimen type differs by sex and is the highest-yield exam distinction.
- Rectal or pharyngeal NAAT swab - if receptive anal or oral intercourse reported
- Full STI screen - all confirmed cases offered testing for gonorrhoea, HIV, syphilis, and hepatitis B
Serology is NOT used for initial diagnosis - lower sensitivity and specificity than NAATs.
