Specimens to send for chlamydia
Women:
Men:
Women: vaginal or endocervical swab or 1st catch urine
Men: 1st catch urine, urethral swab, rectal swab
Diagnosis/test of choice for chlamydia
Nucleic acid amplification test (NAAT)
Gonorrhea symptomatic?
Asymptomatic

- Most infections are acute & symptomatic
- Urethritis
- Epididymitis
- With purulent discharge & dysuria after 2-5 day incubation period (range: 1-14 days)

Gonorrhea presentation in neonates
Neonatal conjunctivitis
- With profuse exudate and swelling of the eyelids
Specimen(s) to send for gonorrhea
- Discharge ‘down below’— ________
- Conjunctivits— ____
- Gonorrhea pharyngitis— ____
- DGI– ____
Depends on presentations
Eg.
- Discharge ‘down below’— high vaginal swab, endocervical swab, urethral swab, urine
- Conjunctivits— eye swab
- Gonorrhea pharyngitis— throat swab
- DGI– blood culture
Diagnosis/test of choice for gonorrhea
Nucleic acid amplification test (NAAT) on urine or swab samples (Adv: rapid test)
