9 year old male with following lab results : Alkaline Phosphatase 206 Gamma GT 12 ALT 25 AST 29 Lipase 121 Cardiac Muscle Enzymes 160 TSH 127 Glucose 6.2 Potassium 2.9 Urea 4.5 Creatinine 49 Total Protein 73 Albumin 40 Urine Albumin 460 Urinary Creatinine 28.09 UACR 16.7 These labs were drawn from my 9 year old son 10 days ago. Prior to venipuncture, anesthesia was induced with Ketamine IM and then maintained with Sevoflurane via mask / bagging. Due to a history of laryngeal spasm, the Anesthetist was reluctant to intubated unless absolutely necessary. Labs were drawn approximately 15 minutes after anesthesia was established. My son has severe intellectual disabilities, hence the need for anesthesia prior to medical procedures. Can you comment on a differential diagnosis particular to his electrolytes and urinary ACR ? Would the fact that my son had been NPO for 8 hours prior to labs being drawn have an impact on the UACR ?
