Patient :Will a NAAT detect Mycoplasma urethra , Ureoplasma urealyticum, or any other bacteria? I had a NAAT performed on a urine sample for Gonorrhea and Chlamyida, however the test came back negative. From what I am being told, this test is extremely accurate. Will this test also detect other types of bacteria in the urine?
Hello. Welcome to Ask The Doctor.
NAAT tests are very specific and accurate, they are done to pick up common infections at the earliest soon after an exposure.
Mycoplasma and Ureaplasma and all other organisms contain Nucleic acid. NAAT is Nucleic Acid Amplification Test. So it will surely detect the organism.
However, if we talk in particular to these two, we usually do culture to detect them.
In males, a swab from urethral discharge is taken and in females Vaginal swab is taken.
NAAT is able to detect almost all the kinds of bacteria, but the search is target based, means if we want to search Mycoplasma we will do NAAT for it only. The test won't test us if in case any other organism is there.
That's why culture is a preferred test as it can grow any organism.
I hope it helps.
