Requires urine creatinine analysis. Urine samples should be ran only when certain indications exist. Serum is often the preferred sample type when screening for metabolic disease. Please contact Genetics Services or the metabolic lab at (614)722-1535 to help determine if urine analysis is appropriate. If patient is on TPN therapy, please consult Genetics Services first for proper collection procedure.
