Chlamydia
A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise chlamydia — the full SA Note notes add investigations, management, complications and 10 practice questions.
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.
