These tests are very good at identifying chlamydia. A test that is positive almost always means the problem is there and is unlikely to be a false-positive test result. A polymerase chain reaction (PCR) test is an example of a nucleic acid amplification test. This test can also be done on a urine sample.

Negative test results If the test result is negative, you may not be pregnant. However, negative results are less reliable. For example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result.

Nucleic acid amplification tests (NAAT). These tests find the genetic material (DNA) of chlamydia bacteria. These tests are very good at identifying chlamydia. A test that is positive almost always means the problem is there and is unlikely to be a false-positive test result.

However, it's possible for your results to come back negative even if you've contracted the infection within the past few months. This is referred to as a false negative. Your body will typically take several weeks to develop IgG antibodies to HSV.

Herpes blood tests can be negative even though someone is actually infected.

The recommended tests are over 95% accurate in picking up chlamydia. As no test is 100% accurate there's a small chance that the test will give a negative result when you do have the infection. This is known as a false negative result.

Testing sooner than three to 5 weeks post-treatment for chlamydia or gonorrhoea is not recommended to avoid detection of residual nonviable organisms that can give a false-positive result [5, 7].

A negative (normal) test most often means you have not been infected with HSV-1 or HSV-2. If the infection occurred very recently (within a few weeks to 3 months), the test may be negative, but you may still be infected.

Even without symptoms, if you have chlamydia and you don't get it treated it can damage your reproductive system, cause epididymitis, or lead to infertility. That's why it's so important to get tested for STDs if you've had sex without a condom.

Some tests you can buy may be less reliable. Remember that no test is 100% accurate. There is a small chance that a test may show negative even when you have chlamydia. This is called a false negative test result.

['A urine test. A sample of your urine is analyzed in the laboratory for presence of this infection.', 'A swab. For women, your doctor takes a swab of the discharge from your cervix for culture or antigen testing for chlamydia. This can be done during a routine Pap test.']

Chlamydia will not make a difference to this. In an HIV-negative person, having chlamydia can make it more likely that they will be infected with HIV if they are exposed to the virus. Chlamydia can also be passed on from mother to child during childbirth and can affect the baby's eyes and cause pneumonia.
