The NHS has announced that they are introducing a blood test for pre-eclampsia.
This comes after a study showed it can help to diagnose the potentially-lethal pregnancy condition earlier on.
The condition is suspected in around 10% of UK pregnancies, which affects around 80,000 women annually.
The condition usually occurs from around 20 weeks, or soon after a baby is delivered.
It's recognised by high blood pressure and protein in the mother's urine.
So hwo will these blood tests work?
Experts at King's College London found that measuring a particular protein called placental growth factor (PlGF) in a woman's blood, they were able to diagnose pre-eclampsia on average two days sooner.
Lucy Chappell, a professor in obstetrics at King's said, ''We knew that monitoring PlGF was an accurate way to help detect the condition but were unsure whether making this tool available to clinicians would lead to better care for women. Now we know that it does."
The King's team studied 1,035 women with suspected pre-eclampsia from 11 maternity units across the UK.
The women were randomly split into two groups, one of which had the results of their PlGF test revealed to their medical teams.
Their results showed the test reduced the average time to pre-eclampsia diagnosis from 4.1 days to 1.9 days, which is fantastic.
