What is genetic sequencing?

Genetic sequencing or DNA sequencing refers to any method or technology that is used to determine the order of the four bases—adenine (A) guanine (G) cytosine (C) and thymine (T)—in a strand of DNA.

The NIFTY™ test uses genetic sequencing machines to analyse cell free DNA from the mother and baby in order to screen for certain chromosomal abnormalities that might be present in the baby.
