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

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.

Solid Tissue (such as skin biopsy, products of conception, or fetal tissue)

Fresh tissue specimens should be kept at room temperature if it will be transported immediately. If specimen is not being immediately transported to the laboratory, it may be refrigerated; do not freeze. Specimen should be sent by courier or overnight mail to arrive at the laboratory the next day. Chromosome analysis cannot be performed on FFPE samples.
