Hi , I have an appointment to have full blood work done with a haematologist, to test for possibly everything, cancers etc. I am also due to visit my OB/GYN for PAP smear etc. What I want to know is it still necessary to visit my obgyn or will the bloodwork be enough to screen for cervical cancer etc. i do not have any problems now, just want to make sure everything is ok. Im 37 yrs old.
