Most women go on to have a healthy pregnancy after a miscarriage, so tests are not usually offered until a woman has recurrent miscarriages or 1 late miscarriage. This policy can seem frustrating. You’ve been through a traumatic experience and it is completely understandable to want to know why it happened. The reason for the policy is because most women who have 1 or 2 miscarriages will go on to have successful pregnancies.
However, some specialists may see women after 2 miscarriages in a row. It is worth talking to your GP to find out whether you can be referred for tests.
What tests might I have?
Blood tests can be used to check for blood clotting disorders such as antiphospholipid syndrome (APS) and thrombophilia.
Chromosomes are genetic structures in our cells that contain our DNA and the features we inherit from our parents. If your baby had abnormal chromosomes (see below), doctors may do some blood tests to check your and your partner’s chromosomes for abnormalities.
Testing the baby
You should be offered tests to check for abnormalities in your baby’s chromosomes. This is not always possible but may help doctors find out your chances of miscarrying again.
If you have had a late miscarriage, you may also be offered a post-mortem examination of your baby. This will not happen without your permission (consent). Find out more about what happens to your baby after miscarriage.
Tests to look at the shape of your womb
If you have recurrent miscarriages, you should be offered a pelvic ultrasound scan to check for any abnormalities in the shape of your uterus. You’ll be offered more tests if your doctors think there may be a problem.

Tests for infection
If you have had a late miscarriage, you may have blood tests and vaginal swabs to test for an infection.
Where do I have these tests?
The tests are normally done when you are referred to the recurrent miscarriage clinic. Any tests that need to be done at the time of the miscarriage will be done at the Early Pregnancy Unit or hospital.
