Hello there. I can understand your concern. CMP is comprehensive metabolic panel - it's a test for organ function and it will reveal if you are having diseases like for eg. Diabetes, kidney problems etc. HCG- detection of human chorionic gonadotropin which is secreted by placenta. CBC- complete blood count. Reveals the counts of all the cell types in your blood. TSH- thyroid stimulating hormone. There is not a single test which tests for existence of any particular drug in your body from this list. Best regards. Dr. Anil Kumar Jain. Bangalore.
