Screening tests

Your due date is calculated from the first day of your last menstrual cycle.

A blood test together with a STD screening is also performed early in pregnancy.

First Trimester Screening (FTS)
Once gestational age is established the First Trimester Screening Test can be discussed with you and your partner.
This needs to be completed by 13weeks + 5days.
