From: Canadian clinical practice guidelines for the management of anxiety, posttraumatic stress and obsessive-compulsive disorders

Basic lab tests  
• Complete blood count • Fasting glucose
• Fasting lipid profile (TC, vLDL, LDL, HDL, TG) • Thyroid-stimulating hormone
• Electrolytes • Liver enzymes
If warranted  
• Urine toxicology for substance use  
  1. Adapted from references [32, 53]. HDL = high density lipoprotein; LDL = low density lipoprotein; TC = total cholesterol; TG = triglyceride; vLDL = very low density lipoprotein.
