A serum chemistry panel may be helpful in evaluating for renal or liver disease. Free or total testosterone, luteinizing hormone (LH), estradiol, and dehydroepiandrosterone sulfate levels are used to evaluate a patient with possible feminization syndrome. Obtain thyroid-stimulating hormone (TSH) and free thyroxine levels if hyperthyroidism is suspected.
