All you really need to order is a sensitive estradiol assy and prolactin.
If you'd also like to know your blood counts and TT then order The Hormone Panel with Estradiol Sensitive and Testosterone LC/MS-MS and add the prolactin serum assay.

I've always had lab results in 2 days but usually 24 hours after blood work when using private me labs.
A general rule of thumb is that if you keep e2 within range by using an AI then prolactin shouldn't be an issue.
Also, it's not a good idea to change AI dose without having the results of blood work.
