Measurement of the serum albumin concentration is essential to distinguish pseudohypocalcemia from true<unk> .  Laboratory investigations that detect alterations in parathyroid hormone, vitamin D, and phosphate in the serum or urine aid in the differential diagnosis of the underlying etiologies. Other laboratory tests include serum alkaline phosphatase, liver function tests, coagulation profile, blood urea nitrogen, creatinine, and urinary cAMP levels at baseline or after PTH challenge.
