Preparing parental blood samples for possible confirmation testing if an abnormality is detected on the prenatal array sample
DNA extraction of the maternal blood sample used for maternal cell contamination testing
This test can only be ordered on the parents when a prenatal microarray test has been ordered on the fetal sample.
This test ID contains no charge and serves as a way to correlate proband and parental specimens. If additional testing is warranted, the appropriate tests will be added.
When prenatal microarray analysis is ordered, parental blood samples are collected and prepared for confirmation studies should an abnormality be detected on the prenatal sample. If an abnormality is detected on the fetal sample, the most appropriate testing (microarray, FISH, or chromosome analysis) to aid in the interpretation of the prenatal result is performed on the parental samples. A paternal blood sample is desired but not required.
Maternal cell contamination testing will be performed on the maternal blood and prenatal samples to rule out the presence of maternal cells in the fetal sample.
In order to interpret equivocal array results on a prenatal sample (amniotic fluid or chorionic villus), parental studies are performed to determine if the abnormality detected on the prenatal array is inherited or de novo.
Maternal cell contamination testing is performed on the maternal blood and prenatal sample to detect the presence of maternal cells in the fetal sample.
An interpretive report will be provided.
No interpretation will be provided. This test is for sample processing only.
