When asking about lab tests for weight loss injections (e.g., GLP-1 agonists like semaglutide), you should know that clinical blood work is essential before starting: fasting glucose, HbA1c, kidney function (creatinine, eGFR), liver enzymes (ALT, AST), and thyroid (TSH). These ensure safety and monitor efficacy. A DNA test (e.g., for TCF7L2 or GLP-1 receptor variants) may offer insights into individual response, but evidence is moderate (GWAS, not clinically validated). Consumer genetic tests are not a substitute for medical supervision. Important: these injections are prescription-only; self-administration is risky. MyBody-X tests provide complementary, non-diagnostic data. Always consult a healthcare provider for interpretation and treatment decisions.
