My child is constant tachycardia - 24 hr urine 706 mg/day of creatinine& 21.5 cortisol. Tsh elevated
His blood serum creatinine was normal, but his tsh went way high& then back down. I can't get a straight answer out of anyone-I know it's a little elevated, but the creatinine/ cortisol ratios per day? He's only 8! Idk?
