In addition, the effects of PTH on
kidney function
and bone strength indicate that serum calcium, phosphorus,
and creatinine levels should be measured together with PTH. The creatinine test measures kidney function and aids in the diagnosis of parathyroid dysfunction.
Description
The PTH test is performed on a sample of the patient's blood, withdrawn from a vein into a vacuum tube. The procedure, which is called a venipuncture, takes about five minutes.
