What it is

This test looks for the genetic material of Chlamydia trachomatis using a nucleic acid amplification test (NAAT), the most accurate type of chlamydia test. It is run on a urine sample or a swab and is used for routine screening and when there are symptoms.

What the price covers

The price usually covers the chlamydia test only. The visit, the sample collection and a gonorrhea test on the same sample (87591) are usually billed separately.
