I took the list to the MFM after I got the referral to see him. I asked him what tests he'd be running, and he listed all of these so I didn't have to "ask" for anything specific. I think it worked well...it wasn't like I was telling him how to do his job. and he may have other testing that he/she does normally too. My MFM does some additional genetic testing if there was a HELLP diagnosis. I wouldn't worry about asking the OB for the tests, but rather focus on getting the referral. I actually called the OB and asked for the referral over the phone, rather than bothering with an appointment.
The OB may or may not know about all the tests, but the MFM will, and he/she will know the best lab to send the tests to for proper results. My MFM has ONE lab he sends coagulatopathy tests too...and only one because they are known to be specialists in those tests.
You can probably expect to have a CBC, and liver panel run, as well as a 24 hour urine to get a prepregnancy baseline.
