Total Serum test will let me know if my gear is bunk???

[MissyM]

I asked this in another thread but didn't get many responses. I have questionable results from test e I am on and plan on getting a blood test this week. Which test will let me know if gear is bunk? Total serum or Free and total? Any reason to pick on over the other? Total is just around $45 and total and free is $90. Thank you in advance!!!
