Brief Answer: Parathyroid Detailed Answer: Blood levels of parathyroid hormone are typically interpreted only in conjunction with blood calcium levels. Often, other lab results like 25 hydroxy vitamin D and phosphorus levels are helpful in providing greater meaning to the parathyroid levels. Generally speaking, if the blood calcium levels are normal, then a low parathyroid level is likely an 'artefact' ie probably a laboratory error. If calcium is low, and parathyroid is also low, then it is abnormal and the condition is called 'hypo-parathyroid-ism'. If the calcium and/or vitamin D levels are low, the normal compensatory response of the body is to raise its parathyroid level. In such cases, one expects the parathyroid to be high. Likewise, when the calcium is high, the parathyroid status can be used to determine the likely causative condition.
