| name | Chromosome 19 polysomy [Presence] in Tissue by FISH | ||
| description | This test determines if chromosome 19 polysomy is present in tissue (tumor) specimens. Polysomy is defined as 3 or more signals for 1q and/or 19p in >30% of tumor cells with concurrent 1p/19q deletion.[PMID: 19808867] Chromosome 19 polysomy is a prognostic indicator of poorer outcome for oligodendroglioma patients. | ||

| component | Chromosome 19 polysomy | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| 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. | ||
