Nucleic Acid Amplification Test (NAAT)
Highly sensitive, highly specific molecular testing performed in our CLIA-certified high-complexity laboratory.
Sensitivity commonly >90–95%, specificity >98%
Significantly reduces false negatives and false positives compared to serology
NAAT delivers the highest level of diagnostic confidence available today.
Timing changes outcomes
Identify infection earlier than antibody or antigen tests and enable faster diagnosis.
NAAT detects infection sooner — when clinical intervention matters most.
Multiplex testing detects multiple pathogens from a single specimen reducing repeat testing.
NAAT combines accuracy and efficiency without compromising care.

The Gold Standard for Infectious Disease & Molecular Diagnostics
What is NAAT?
NAAT (Nucleic Acid Amplification Testing) is a molecular diagnostic method that detects pathogen-specific DNA or RNA directly from patient samples. Unlike antibody or antigen testing, NAAT identifies active infection, not immune response. This testing method detects genetic material (DNA/RNA), identifies infection earlier, and is applicable across viral, bacterial, and fungal pathogens.
NAAT vs Traditional Testing
NAAT (nucleic acid amplification testing) is considered the clinical gold standard for many infectious disease diagnostics because it detects active infection directly and identifies pathogens earlier than other testing methods. NAAT offers high sensitivity (often greater than 90%) and high specificity, resulting in fewer false positives and more reliable results. In comparison, antibody tests do not detect active infection and rely on a delayed immune response, with more variable accuracy. Antigen tests may detect active infection in some cases but typically have moderate sensitivity and specificity, making them better suited as adjunct tests rather than primary diagnostic tools.
Accuracy & Performance of NAAT
Nucleic acid amplification testing (NAAT) offers high analytical performance for the detection of active infection. Depending on the pathogen and specimen type, NAAT assays commonly demonstrate sensitivity greater than 90–95% and specificity exceeding 98%, supporting reliable identification of clinically relevant infections. By detecting pathogen-specific DNA or RNA, NAAT enables earlier detection than serologic testing, which relies on host immune response. Test performance may vary based on pathogen, specimen type, and clinical context.
False Positives & Negatives NAAT
False positive results with NAAT are uncommon and are most often associated with laboratory contamination or improper sample handling. At Genome-Based Diagnostics, these risks are minimized through strict laboratory protocols, internal quality controls, and high-complexity testing standards. False negative results may occur if testing is performed very early in infection or if specimen quality is insufficient. These risks are reduced through optimized collection methods and validated amplification protocols, supporting accurate and dependable results.
Clinical Benefits of Nucleic Acid Amplification Testing
NAAT provides meaningful clinical advantages by enabling earlier detection, reducing missed diagnoses through high sensitivity, and limiting unnecessary follow-up testing through high specificity. Multiplex testing capabilities allow simultaneous detection of multiple pathogens from a single specimen, improving efficiency and turnaround time. Together, these benefits support greater diagnostic confidence and informed patient management.
Limitations & Considerations
While NAAT is a powerful diagnostic tool, results should be interpreted within the appropriate clinical context. NAAT detects genetic material rather than infectivity, and residual nucleic acids may persist following successful treatment. As with all diagnostic testing, clinical correlation and provider judgment remain essential for optimal patient care.
