Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like sore throat, fever, or swollen lymph nodes, or if you’ve been exposed to someone with a throat infection caused by *Chlamydia*. It’s also used in certain screening programs for sexually transmitted infections (STIs).

What to Expect During the Test

A healthcare professional will swab the back of your throat using a sterile cotton-tipped swab. The swab is then sent to a lab for culture. This is a quick, painless procedure with no downtime.

How the Results Are Interpreted

Results are qualitative—meaning they indicate either a positive (growth of *Chlamydia* bacteria) or negative (no growth) finding. A positive result means you likely have the infection and may need treatment.

What Happens Next?

If the test is positive, your provider will prescribe antibiotics to treat the infection. Follow-up testing may be needed to ensure the infection is cleared. If negative, further evaluation may be required if symptoms persist.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Chlamydia throat infections can cause complications if untreated, such as spreading to other parts of the body or worsening symptoms. Early detection and treatment are crucial to prevent complications and reduce transmission to others.
