The Society for Maternal-Fetal Medicine concurs that ICP should be diagnosed when the total bile acids (TBA) or serum bile acids are measured at 10 micromol/L and above. Blood tests for ICP/OC. It is a diagnosis that is made once other causes of itching and abnormal liver function Obstetric cholestasis (OC) is a liver disorder that occurs specifically in pregnancy, and affects 0.7% of women in the UK.

Y If the condition isn’t properly treated, it can lead to serious health consequences.

The diagnosis of obstetric cholestasis is suspected if, while pregnant, you develop an itch without any skin rash to explain the itch. 7, 8 OC is characterised by pruritus, occasionally jaundice, raised liver enzymes and increased serum bile acids (SBA), with the measurement of SBA considered to be the most important biochemical marker for both the diagnosis and monitoring of OC. It was not possible to investigate the effects of bile acids on the intact human fetal heart at a cellular level. Obstetric cholestasis.
