My daughter is 21 year old. Her doctor has ordered blood test

This answer was rated:

My daughter is 21 year old. Her doctor has ordered blood test for Prolactin level. She is currently on YAZ and she is not advised to stop the YAZ. I am wondering whether the test result will be reflecting her true Prolactin level? Is there a way a doctor can calculate the true level is she knows that patient is on YAZ when taking the test?

mysticdoc :

Hello,

mysticdoc :

Thanks for your question.

mysticdoc :

There is no way to calculate prolactin level while being on Yaz or any birth control pill.

mysticdoc :

The test result will be affected.

mysticdoc :

Prolactin level will be falsely low.

mysticdoc :

Hence, it is better to stop yaz for at least 24 hours before doing the prolactin level.

Customer:

OK, thank you.
