Chlamydia DNA Detection by Nucleic Acid Amplification Probe (Genetic Test)
This test checks for the presence of genetic material from *Chlamydia trachomatis*, a common bacterial infection that can affect the genitals, throat, or eyes. It helps diagnose infections that may not cause obvious symptoms.
["A simple test to detect a sexually transmitted infection (STI) that can cause serious health problems if untreated."]

Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms like unusual discharge, pain during urination, or unexplained pelvic pain. It’s also used as a routine screening for sexually active individuals at higher risk of infection, such as those with multiple partners or new sexual partners. Some women may get this test during annual exams or before pregnancy.
How the Test Works
The test uses a small sample of urine (or sometimes cervical/vaginal swabs) to detect genetic material from *Chlamydia*. A special probe targets the bacteria’s DNA, and a machine amplifies and identifies it. This method is highly sensitive and accurate for detecting even small amounts of infection.
Sample Collection
You’ll likely provide a urine sample in the morning, or a swab may be collected from your cervix (for women) or urethra (for men). No special preparation is needed, but avoid urinating right before the test if a swab is used.
Test Results and Follow-Up
Results are usually available within a few days. If the test is positive, your provider will prescribe antibiotics to treat the infection. Follow-up testing may be needed to confirm treatment success. If negative, retesting is recommended if symptoms persist or you’ve had recent sexual exposure.
