Conjunctival Swab:
Conjunctiva is a tissue inside the eye that attaches the pupil with the eyeball and aids in vision.
The Conjunctival Swab for Bacterial Culture and Sensitivity (Aerobic) Gram Stain Lab Test is a clinical test that checks for bacteria in the conjunctiva of a patient suspected to have a bacterial infection, such as conjunctivitis and chlamydia. The timely detection allows for early control of the bacteria that may cause mild or serious infections.
A sample of the conjunctiva is collected with a cotton swab. The sample is further prepared with various solutions and observed under a microscope in the laboratory to determine the type of bacteria present.
