Glossary Term
A control sample that is known to produce a positive result if the test is working as expected.
Glossary Term
The probability that a test will produce a true negative result when used on non-effected subjects as compared to a reference or "gold standard". The specificity of a test can be determined by calculating: number of true negative results divided by the sum of true negative results plus number of false positive results.
Glossary Term
A PCR format that partitions each sample into thousands of sub-reactions and calls each partition positive or negative, giving absolute quantification without a standard curve. Useful for low-level targets, copy-number work, and reference material characterization; throughput and per-test cost differ from qPCR.
Glossary Term
A statistical method used for multiple testing corrections to control the expected proportion of false positives (Type I error) among rejected tests or hypotheses. It is less stringent than other multiple testing corrections and thereby, will allow a percentage of false positives.
Glossary Term
A test result that shows evidence of a result or condition although it is not actually present.
Glossary Term
Problem associated with the device incorrectly reporting that something has been detected and may mislead the operator to take certain actions.
Glossary Term
