What is workup done for hypoparathyroidism?

Autor: H K



Respuesta:

PTH (Primary hypoPTH low PTH and low Ca, pseudohypoPTH elevated PTH due to resistance to PTH by receptors, secondary hypoPTH low PTH and high Ca) Be careful that calcium may be protein bound, so hypoalbuminemia drops total Ca and elevated proteins elevate Ca all w/normal ionized Ca maybe. So see albumin (every 1g/dl fall albumin, Ca fall 0.8mg/dl) Alkalosis causes more albumin binding causing decrease in ionized Ca in serum and trigger hypocalcemia Other tests may include (vitamin D 25 hydroxy, serum Mg, serum Ph)
