Aneuploidy Screening
QF-PCR
Real-time quantitative PCR (qPCR) is a simple modification of PCR to quantify the amount of target DNA by introducing fluorescent or intercalating dyes used to measure gene expression or gene quantification including contiguous gene deletions or duplications. A simple method is described to quantify DNA copy number from human samples.
Maternal Cell Contamination (MCC)
The potential presence of maternal cells in CVS or AF samples poses a significant preanalytical risk for prenatal misdiagnosis. This is particularly of concern with sensitive polymerase chain reaction (PCR)-based molecular assays that may lead to a positive result based on the presence of a very small amount of mutation-positive maternal cells.
Note: For AF*/CVS*/Cord Blood- Maternal cell contamination(MCC) is recommended in all prenatal tests. In its absence the laboratory is not liable for the accuracy of fetal test results.
Acceptable sample
- 4ml Maternal blood
TAT: 7 Working Days
