What labs to have done and how often?

I had RNY 2 years ago. I had labs done 3 months, 6 months, 12 months, 18 months and 2 years post op. 

I have a new pcp, so I took the following list of labs to ask to have him run:

• COMPREHENSIVE METABOLIC PROFILE (sodium, potassium, chloride, glucose, BUN, creatinine, calcium, total protein, albumin, total bilirubin,alkaline phosphatase, aspartate aminotransferase) (Nc,K,C1,CO2,Glu,BUN,Cr,Ca,TP,Alb,Tbili,AP,AST,ALT)
• LIPID PROFILE (cholesterol, HDL, LDL, triglycerides, chol/HDL ratio) (Fasting specimen) , Tchol,Trig,HDL,Calc,,LDL)
• ALT (SPGT)
