The PTH Blood Test uses one sample to measure a defined set of markers. Here is what the PTH Blood Test covers and how to understand the report from a licensed laboratory.

How Often to Repeat the PTH Blood Test

How often the PTH Blood Test is repeated depends on why it was ordered and what your provider recommends. For routine monitoring, the PTH Blood Test may be repeated at regular intervals to track the same markers over time. If a result from the PTH Blood Test is outside the range, a provider may suggest repeating it sooner. Parathyroid hormone (PTH) levels are measured by this blood test to help diagnose parathyroid disease.

What the PTH Blood Test Can and Cannot Tell You

The PTH Blood Test cannot capture factors that are not part of the panel, such as symptoms or medical history. A normal-looking PTH Blood Test result does not rule out every possibility, just as an abnormal one is not a diagnosis. The PTH Blood Test is most useful when its results are interpreted together with your overall health picture. For questions the PTH Blood Test cannot answer, a provider may recommend other tests or an evaluation.

High and Low PTH Blood Test Results in Durham

A single high or low value from the PTH Blood Test may reflect normal variation, so repeat testing is sometimes used. The meaning of a high or low PTH Blood Test result depends on your history and on the other markers in the panel. Reference ranges for the PTH Blood Test are printed on the report, and results should be read against that range. If a PTH Blood Test value is outside the range, a provider can explain the possible reasons and the next steps.
