My daughter who is now 30 weeks has been suffering from itching palms, she contacted her midwife who took blood to have tested, at her next appointment the midwife said that she had only tested for liver function and not bile acids , she then took another test and after a further 5 day wait ,thank god, the test came back normal, I hate to think about the fact that all this time there could have been a problem, she has low iron though.
