Search Links: General Info : Protocols : LabTestsOnline

DescriptionMany organisms can cause bacterial conjunctivitis. Prior to taking a swab it is advisable to wash off any obvious pus after which the swab should be taken from the conjunctiva. Please take a swab sample from each eye. Some causes of conjunctivitis require specialist detection methods e.g. adenovirus or chlamydia (see separate Tests and Tubes entry). Automated liquid culture is used with manual plate reading
Indication Investigaton of bacterial causes of conjunctivitis, for invasive eye disease see Ophthalmic culture
Additional InfoWhere gonococcal infection is suspected, this should be stated on the request form and eye swabs should not be refrigerated as N gonorrhoea is unlikely to be recovered after refrigeration. Swabs must be received in the laboratory within 24 hours. An Aptima sample for combined NAAT test for Gonorrhoea/Chlamydia may also be indicated - see separate Tests and Tubes entry.
