NIPT (non-invasive prenatal
testing) Overview
4. 4
To better understand non-invasive pregnancy screening, it is
helpful to understand what the test screens for.
A chromosome is a structure that holds our genes, and our
genes determine how our bodies develop and function, as
well as our physical characteristics.
We all have 46 chromosomes in each of our cells - 23 of which
are received from our mother and 23 from our father.
However in some instances, babies may have a duplicated,
missing, or abnormal chromosome which could affect their
physical and intellectual development
What is a chromosome?

A chromosomal abnormality can have a minor or major impact on
your baby’s development.
Types of chromosomal abnormalities:
• Monosomy - when there is a missing chromosome
• Trisomy - when there is an extra chromosome
• Microdeletions - when a part of a chromosome is missing or
defective
