Reference range 1. 5 mL Collection Instructions: Fasting specimen is preferred. 0 mL Minimum Volume: 3. If collecting serum instead of plasma, tubes should be centrifuged immediately after clotting. Times include storage and transport time to ARUP. This test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. Parathyroid hormone (PTH) is secreted by the parathyroid glands and plays an important role in calcium homeostasis. Remarks Additional specimen collection, transport, or test submission information. PTH (parathyroid hormone) testing typically requires a lavender-top (EDTA) tube for plasma samples or a green-top (heparin) tube for whole blood samples. 5 mL Minimum Volume: 1. Parathyroid hormone (PTH) regulates calcium levels in your blood and keeps them stable. Welcome to the Melbourne Pathology Test Collection Manual Enter the name of the test you are looking for and click 'Search for Test'. The results should always be assessed in conjunction with the patient's medical history, clinical examination, and other findings. PTH is secreted in response to decrease in serum calcium levels by increasing the renal reabsorption of calcium and lowering reabsorption of phosphorus. An increased (positive) parathyroid hormone-related protein (PTHrP) result with ionized hypercalcemia and concurrent suppression of parathyroid hormone (PTH) adds support for humoral hypercalcemia of malignancy. Although it can be tested on serum or plasma from an EDTA tube, serum sample are unstable and must be immediately placed in an ice slurry before leaving the patient, then centrifuged at refrigerated temperatures. Learn more. There is limited good quality evidence available, but PTH testing sometimes appears to be a useful but imperfect addition to cytology.

Specimen Collection Criteria INPATIENTS ONLY: Collect: One dedicated Lavender-top EDTA tube. After venipuncture, immediately invert tube several times to ensure complete mixture. Testing PTH levels can help diagnose the reason for low or high calcium levels and can show if there is a problem with your parathyroid gland or if it is due to other causes. In the presence of normal renal function and hypercalcemia, an intact PTH level of >65 pg/mL is highly suggestive of primary hyperparathyroidism. Gel tubes are acceptable.
