What is urine NAAT?

An alternative to cervical or urethral cultures is nucleic acid amplification tests (NAATs) that can be performed on urine samples. Three types of NAAT are commercially available: polymerase chain reaction (PCR), transcription-mediated amplification, and strand displacement amplification.

Why is NAAT used to detect chlamydia?

Nucleic acid amplification tests (NAATs) are recommended for the diagnosis of chlamydia and gonorrhoea due to their high sensitivity and specificity,1–3 but a variety of urogenital specimens (ie, urine, cervical and vaginal) are used for testing at clinic level.

What shows up in urine test for chlamydia?

A urinalysis can give clues to the presence of sexually transmitted infections. A positive dipstick for leukocyte esterase or increased numbers of white blood cells in the microscopic exam is suggestive of chlamydia or gonoccocal infection.

Can chlamydia be detected in a urine sample?

Urine testing is currently primarily used to detect bacterial STDs. Chlamydia and gonorrhea urine tests are widely available. Trichomoniasis urine tests are also available, but they are less common. The gold standard for diagnosing bacterial STDs, such as chlamydia and gonorrhea, used to be bacterial culture.

How do you use NAAT for chlamydia?

NAAT is the preferred method for detecting a chlamydia infection. This type of test detects the genetic material (DNA or RNA) of Chlamydia trachomatis. It can be performed using a urine sample or swab of fluid taken from a site of potential infection such as the urethra, vagina, rectum, or eye.

What can NAAT test for?

A Nucleic Acid Amplification Test, or NAAT, is a type of viral diagnostic test for SARS-CoV-2, the virus that causes COVID-19. NAATs detect genetic material (nucleic acids). NAATs for SARS-CoV-2 specifically identify the RNA (ribonucleic acid) sequences that comprise the genetic material of the virus.

How is NAAT performed for chlamydia?

What is the NAAT test for chlamydia?

Nucleic acid amplification tests (NAATs) are the most sensitive tests for the screening and diagnosis of genital chlamydial infections (6). NAATs are more sensitive than previously available diagnostic tests (culture, antigen detection, or nucleic acid hybridization) by at least 20 to 30%.

Does chlamydia show bacteria in urine?

Chlamydia tests use a sample of body fluid or urine to see whether chlamydia bacteria ( Chlamydia trachomatis) are present and causing an infection. Normal: No chlamydia antigens or DNA are found. If a culture is done, no chlamydia bacteria grow in the culture.

What is the urine test for chlamydia and gonorrhea?

Test for Chlamydia and Gonorrhea during routine Pap tests. The urine based nucleic acid amplification test (NAAT) can be used for asymptomatic female patients who are not due for a Pap test but have a risk factor. Tell your patients if their test is positive, a public health nurse will be calling for follow up.

How long does it take to run a NAAT test?

Some NAATs are considered rapid tests that are performed at or near the place where the specimen is collected and can provide the result within minutes, whereas the time to complete laboratory-based NAATs ranges from less than an hour to more than a day.

How do you collect Naat?

Put the swab 1 inch into the rectum and rotate for 5-10 seconds. Remove the cap from the swab specimen transport tube, making sure not to spill any liquid. Immediately place the specimen collection swab into the transport tube. Carefully break the swab shaft at the score line; use care to avoid splashing of contents.
