5 Reasons Why Pregnancy Blood Tests Are Important

Updated: Oct 12, 2023

Are you unsure about getting your pregnancy blood tests? During pregnancy, blood tests can be helpful for a number of reasons from finding out pregnancy complications to possible inherited disorders your baby could have. It is always best to be prepared in pregnancy. Normally hospitalswill offer you intensive diagnostic tests such as such as chorionic villus sampling and amniocentesis if the combined screening test gives a high risk result. Let’s take a look at all the things you can find out from a regular pregnancy blood test that will help you be prepared for your bundle of joy.

Combined Blood Screening Test


Firstly, you can find out the age of your fetus through a pregnancy blood test. This helps the doctors determine how far along you are. In addition to this, blood tests can test for a number of things like the blood count, the blood group and the Rhesus status of you and the baby. This is extremely important in the case of the mother and baby having different blood groups or Rhesus statuses.


A blood test makes it easier to detect pregnancy compilations like multiple pregnancies, ectopic pregnancies, molar pregnancies, and miscarriages. This can be crucial to the health of both the mother and the baby.


Women are likely to develop Gestational Diabetes (GDM) commonly in the third trimester. It is a condition where the glucose levels in your blood stay high. Left untreated this can cause complications during your pregnancy and birth. A simple blood test can help you avoid this. GDM usually disappears after the baby is born but, in some women, it can later turn into type 2 diabetes later in life.


Some dangerous infections can be transmitted from the mother to the infant during the pregnancy. In such cases, a blood test can screen for the possible infection minimizing the risk to the baby’s health. Diseases like HIV, Syphilis and Hepatitis are normally screened during routine tests. If tested positive, the baby is given specialist care and treatment along with medicines and planned care of the birth. A pregnancy blood screening can reduce the risk of passing it on to the baby from 1 in 4 chances to less than 1 in 100.


Blood tests can help detect inherited blood disorders like sickle cell anaemia & thalassaemia which are passed through the parent’s haemoglobin genes. Pregnancy blood tests can also determine the likeliness of your baby having Down’s syndrome. According to the NHS, 1 in 700 babies born in the UK has Down’s syndrome. Other conditions like Edward’s syndrome and Patau’s syndrome are conditions that can be detected through a blood test. The detection of a high-risk screening result for the conditions means your baby gets the special care that they need as soon as possible.
