Treatment of ICP: blood tests
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, meconium-stained amniotic fluid, admission of the baby to the neonatal unit and stillbirth.
Blood tests are described in more detail in How is ICP diagnosed?.
