Q
What type of test is done with the DNA sample from CVS or Amniocentesis?
A
Type of test done depends on the genetic disorder that they are looking for. The timing of the test also depends on the genetic disorder.
Karyotype - done if there is a chromosomal abnormality in the family. E.g. if the parents are carriers of a balanced translocation. Results in 2 weeks (dependent upon the cells growing)
QF-PCR (Quantitative Fluorescence PCR) - samples to Guy’s Hospital laboratory and looks for t13, 18 & 21 (plus sex chromosomes if disorder suspected). Results: 24-48 hours
