Test ID: CMAP
Chromosomal Microarray, Prenatal, Amniotic Fluid/Chorionic Villus Sampling
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Prenatal diagnosis of copy number changes (gains or losses) across the entire genome
Determining the size, precise breakpoints, gene content, and any unappreciated complexity of abnormalities detected by other methods such as conventional chromosome and fluorescence in situ hybridization (FISH) studies
Determining if apparently balanced abnormalities identified by previous conventional chromosome studies have cryptic imbalances, since a proportion of such rearrangements that appear balanced at the resolution of a chromosome study are actually unbalanced when analyzed by higher-resolution chromosomal microarray
Assessing regions of homozygosity related to uniparental disomy or identity by descent
Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request
Cultures from this specimen will be discarded 10 days after all cytogenetic test results have been reported. If further testing is desired, call the laboratory at 507-284-1668.
Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
Maternal cell contamination (MCC) testing will be performed at no additional charge if a maternal blood sample is received to rule out the presence of maternal cells in the prenatal sample, see Additional Testing Requirements.
If an insufficient sample is received or MCC is identified in the prenatal sample, microarray testing will be performed on cultured material.
