<s>[INST] My wife is 24 weeks pregnant, and has to go for weekly blood pressure readings as there is a history of pre-eclampsia in the family, and they found a notch on the doppler test at 20 weeks. She does not seem to have any signs of pre-eclampsia as blood pressure is normal, no problems protein in urine, and none of the other symptoms, but she had blood tests recently and the results have come back with a higher than normal ALT reading (84). She is due to have further tests next week but is a little worried by the results. What could it be? [/INST] Hi, Liver enzymes do get slightly elevated in pregnancy, since everything else is in normal range, you need not be worried. The fact that she is due for more tests and also the fetus is being monitored regularly by ultrasound means that her antenatal care is adequate. If any concerns show up on the blood test these can be discussed with a maternal medicine expert or a hepatologist. Hope this helps. Regards. </s>
