Glossary Term
A set of values of particular type of measurement that is used to interpret corresponding observation results.
Glossary Term
An instrument designed to measure the size of an opening or one used to increase the diameter of an opening; can also refer to a standard or reference material used to set the operating parameters of an instrument.
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.
