G-banded karyotyping for the detection of numeric chromosome abnormalities, balanced and unbalanced chromosome rearrangements, and polyploidy.
Karyotype Genetic Testing | Hereditary Disorders
A karyotype is a test to evaluate the size, shape, and number of chromosomes. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with growth, development, and body functions. A karyotype is often a helpful test to determine the genetic contribution to a constellation of medical and/or developmental problems. Karyotype requires minimum 4 cc whole blood in green top (sodium heparin). At least one dedicated tube for karyotype is required. If requesting multiple test, please submit additional tubes. Blood in EDTA or other specimen types cannot be processed for karyotype.
