| description | The quantification of NPM1 mutation A (c.956dupTCTG) transcripts are compared to a control gene (e.g. ABL1) by real-time PCR (RT-qPCR). NPM1 primers and probes spanning exons 11 and 12 may be used to detect quantify the NPM1 mutation transcripts. Results are based on the normalized copy number [NPM1 mut D copy number/ABL1 copy number) x 100]. This test is based on, but not limited to, IPSOGEN'S NPM1-A MutaQuant Kit, which is used as research tool (as of 2012) for the quantification of NPM1 transcripts in samples previously identified as carrying the NPM1 mutation A. The results are used to monitor the decrease of NPM1 mutA expression after treatment. | ||

| property | NRto = Number Ratio | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Bld/Tiss Bld = Whole blood Tiss = Tissue, unspecified | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
| method | Molgen = Molecular Genetics: General class of methods used to detect genetic attributes on a molecular basis including RFL, PCR and other methods. | ||
