Special Info

While chromosomal microarray is widely used in postnatal situations, this same technology can be applied to investigate chromosomal aberrations in prenatal cases as well. A few examples include cases of recurrent pregnancy loss, spontaneous abortions and intrauterine fetal demise. Chromosomal microarray can also aid in further delineation of abnormalities found by conventional cytogenetics in prenatal cases, or can be used to find results in cases of poor or no growth, where sufficient metaphases were not obtained to complete a full cytogenetic analysis.

Clinical Info

Reflex tests: Chromosomes and FISH. This tests may incur additional charges.
