Cost Analysis of a Nucleic Acid Amplification Test in the
Introduction The Centers for Disease Control and Prevention has recommended using a nucleic acid amplification test (NAAT) for diagnosing pulmonary tuberculosis (TB) but there is a lack of data on NAAT cost effectiveness. Methods We conducted a prospective cohort study that included all patients with an AFB smear positive respiratory specimen at Grady Memorial Hospital in Atlanta, GA, USA
HIV Testing Find free testing and KNOW your status
Nucleic acid test (NAT)A nucleic acid test is a blood test that gives results in less than a week. A nucleic acid test is sometimes called a viral load test. This test is used to confirm an HIV infection. It is not routinely used unless an individual has a positive rapid HIV test or positive combination HIV test.

Testing HIV Basics HIV/AIDS CDC
The window period varies from person to person and depends on the type of test used to detect HIV. Ask your health care provider or test counselor about the window period for the test youre taking. A nucleic acid test (NAT) can usually tell you if you have HIV infection 10 to 33 days after an exposure.
What is the nucleic acid test (NAT)? Blood Basics
The nucleic acid test (NAT) system can detect the presence of bacteria and viruses (e.g. human immunodeficiency virus (HIV) and hepatitis C virus (HCV)) in blood using a semi automated system and further ensures the safety of blood products, including fresh frozen plasma, red cells, and platelets by permitting earlier detection of infections in donors.
What is the nucleic acid amplification test? Quora
Jul 24, 2018 Nucleic acid testing (NAT) involves the infectiousness of hepatitis C virus and HIV in the blood supply. The technique involves molecular methods for screening blood samples to lessen the risk of transmitted diseases. NAT is a technique that is hi

Cost Effectiveness of Pooled Nucleic Acid Amplification
Sep 28, 2010 However, routine tests for HIV infection that measure antibodies in the blood often give false negative results in people with AHI because of the time lag between infection and seroconversion. Nucleic acid amplification testing (NAAT), which detects HIV genetic material in the blood, is a more accurate way to diagnose AHI but is expensive.
Assessment of eight nucleic acid amplification
Nucleic acid amplification technologies (NAATs) are high performance tools for rapidly and accurately detecting infectious agents. They are widely used in high income countries to diagnose disease and improve patient care. The complexities associated with test methods, reagents, equipment, quality control and assurance require dedicated laboratories with trained staff, which can exclude their
