Amplification Assays
Nucleic acid amplification testing (NAAT) is the preferred method for STD testing (CDC guidelines)
Nonamplified methods are appropriate in some circumstances
Advantages of amplified testing include:
Greater sensitivity than alternative approaches
Can detect very small quantities of target specimen
Disadvantages include:
Amplification systems are more difficult to implement due to the risk of cross-contamination, which can result in
false-positive
results
Trace amounts of airborne carryover between samples can be detected by modern amplification systems
Amplification assays are also subject to
inhibition
Inhibition occurs when specific molecules in the specimen
(inhibitors)
block the activity of enzymes in the reaction mix
Inhibition causes
false-negative
results
