Treatment of ICP: blood tests
Note: This page will be updated in light of the research by Chappell et al 2019, which shows that UDCA is not an effective treatment for ICP.
Your doctor should monitor your bile acid levels and liver function. These tests are often performed weekly, but the frequency may depend on how many weeks pregnant you are. Although the itch is not thought to be directly linked to the level of bile acids, if your itching suddenly becomes worse it is reasonable to request that your blood is tested. This is particularly important because bile acid levels above 40 µmol/L are associated with an increased risk of spontaneous preterm labour and potential admission of the baby to the neonatal unit, and levels above 100 µmol/L are associated with stillbirth.
Blood tests are described in more detail in How is ICP diagnosed?.
