nucleic acid amplification test , NAAT (abbreviation)

Nucleic acid amplification tests are the recommended method of diagnosis for gonorrhea and chlamydia.

A probe test is very accurate but is not as sensitive as nucleic acid amplification tests.

Nucleic acid amplification tests can be considered as an alternative to culture for diagnosis and screening for gonorrhea.

Nucleic acid amplification test.

Chlamydia trachomatis using a nucleic acid amplification test on urine or urethral specimens; and 2.

Nucleic acid amplification tests and adenosine deaminase testing may allow rapid diagnosis of TB.

The third method includes the nucleic acid amplification tests (NAATs) which are more sensitive.

• Nucleic acid amplification tests (NAATs) have been introduced.

Two other tests can be carried out on a sample from the chancre: direct fluorescent antibody testing and nucleic acid amplification tests.

Nucleic acid amplification tests (NAAT) have revolutionised the diagnosis.

A polymerase chain reaction (PCR) test is an example of a nucleic acid amplification test.

It is recognized that nucleic acid amplification tests (NAATs) are the only available method in some jurisdictions.

More advanced DNA-based tests, such as nucleic acid amplification tests, cannot be used to test for antibiotic resistance.

D. Do a nucleic acid amplification test (NAAT) for gonorrhea on a first void urine.

The Procleix Assays are qualitative in vitro nucleic acid amplification tests for the detection of pathogenic viruses in human plasma.

Chlamydia trachomatis infection is diagnosed by a nucleic acid amplification test, or by the less sensitive enzyme immunoassay and direct fluorescent antibody tests for chlamydial antigen.

For the purposes of donor counseling and treatment, a positive nucleic acid amplification test result should be confirmed using a different set of primers to rule out false positive results.

The DNA test that Dr. Douglas and others described as promising is called NAAT, for nucleic acid amplification test.

WNV commercial screening tests were employed using Nucleic Acid Amplification tests (NAT) on minipools of 6 or 16 member donations.

GOOD NEWS, there is now a urine test available that checks for chlamydia (PCR-based nucleic acid amplification test - say that fast 10 times).

Cervix. When screening for chlamydia, nucleic acid amplification tests (NAAT - i.e. PCR, LCR) on a cervical specimen are normally performed.

Laboratory confirmation of hMPV from a Luminex nucleic acid amplification test (NAAT) was received for three of the four residents from whom viral nasal swabs were taken.

A nucleic acid test, often called a "NAT", (or nucleic acid amplification test / "NAAT") is a molecular technique used to detect a virus or a bacterium.

A NAAT is not recommended as a test of cure.

• If a NAAT is used, follow the manufacturer’s instructions.

The NAAT is a new and highly sensitive test.

Unlike previous methods, NAAT can be used on urine samples.

At the same time, NAAT is both more specific and more sensitive than culture.

Furthermore, part of this higher incidence among men may be attributable to NAAT.

The introduction of NAAT is believed to be a factor in these increases, especially for the males.

Health Canada replied that there are two NAAT centers.

All of the 136 specimens where NAAT was performed were cultured for mycobacteria.

The percentage of strains tested has been decreasing steadily since NAAT was introduced around 1997.

Urine is a preferred specimen for men if a NAAT is performed.

It is also unclear what impact new technology, such as NAAT, has had on observed gonorrhea infection rates.

• NAAT is not approved in Canada for oropharyngeal or rectal use.

This saving could be used to fund some of the additional costs of implementing NAAT testing.

While the introduction of NAAT could account for an initial rise in reported cases, it is unlikely the single and most important contributing factor.

Why include NAAT testing in the amended Regulations?

• NAAT can be used to detect reinfection, after waiting for at least 2 weeks after completion of therapy.

Many mobile units, street programs and rural locales are now using urine NAAT for gonorrhea.

What would the contingency plans include if one of the NAAT centers were not functional (because of an emergency situation)?

Thus, the present generation NAAT (either commercial or 'in-house') are unsuitable for use as a screening tool.

To determine whether urine NAAT for gonorrhea is available in your region please contact your local laboratories.

• There are promising data on the performance of non-culture NAAT tests using pharyngeal specimens.
