There is minimal validation data on the use of GC NAATs on extragenital specimens such as eye swabs. However, taking a swab in cases where extragenital infection is suspected is appropriate.

Please do not use the red-topped virology transport medium (even though that also mentions chlamydia on its packaging). Due to the high sensitivity of all NAAT testing, extra care must be taken in both the clinical and laboratory settings to prevent contamination of samples (and thus false positive results).
