Chromosome Analysis, Routine; Short Study (Blood)

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.

Specimen Requirements

5-7 ml of whole blood in a green top (sodium heparin) tube is needed for chromosome analysis. For newborns and small infants, 2-3 ml of blood in a sodium heparin, green top is acceptable.

Transport Instructions

The specimen should be kept at room temperature and delivered via overnight shipping. Blood samples need to arrive to the lab within 24 hours of blood draw. Do not freeze the specimen.
