What labs should I get before starting GLP-1 medication?

Before starting Ozempic, Mounjaro, Wegovy, or Zepbound, most clinicians order a baseline panel so they can spot real change later. The usual list is hemoglobin A1C, a complete metabolic panel that includes kidney markers (creatinine, eGFR, BUN) and liver enzymes (ALT, AST), a full lipid panel covering LDL, HDL, and triglycerides, and a TSH for thyroid. Many doctors add vitamin D, vitamin B12, and a complete blood count. If you have a history of pancreatitis or gallbladder disease, your prescriber may add amylase or lipase. Phaze stores baselines as the first point on every biomarker trend, so when your A1C drops or your lipids improve a few months in, the change is obvious instead of buried in PDFs.
