Chromosome Analysis, Routine; Short Study (Solid Tissue/POC)

Test Information

Short study chromosome analysis includes routine karyotyping using G-banding, but fewer cells are analyzed than with routine karyotyping. For short study chromosome analysis, a minimum of 5 cells are counted and a minimum of 2 cells are analyzed for chromosomal abnormalities. Short study chromosome analysis can be used to complement other methods such as microarray to detect certain rearrangements that can only be identified by karyotype. A karyotype can detect chromosome abnormalities such as trisomy, monosomy, triploidy, and marker chromosomes as well as balanced and unbalanced rearrangements.
