Specimen Requirements

Specimen Type: Plasma. Container/Tube: Lavender top (EDTA). Specimen Volume: 0.8 mL. Specimen Minimum Volume: 0.4 mL. Collection Instructions: Draw a baseline specimen pre-operatively and the second specimen post-operatively.

Specimen Transport Temperature

Refrigerate ;24 hours/Frozen OK/Ambient NO

Reference Values

PTH, INTACT Conversion factor PTH: pg/mL x 0.1061=pmol/L (molecular weight=9,424). The reference range has been generated from healthy, U.S. northern latitude donors. The upper limit of the reference range is likely to be lower in geographical regions with greater sunlight exposure. In the presence of normal renal function and hypercalcemia, an intact PTH level of 50 pg/mL (5.3 pmol/L) is highly suggestive of primary hyperparathyroidism.
