Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Parathyroid Hormone (PTH), Intact is a hormone produced by the parathyroid glands, located behind the thyroid, that plays a critical role in maintaining calcium and phosphorus balance in the body. PTH regulates calcium levels by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and reducing calcium excretion by the kidneys. These actions are essential for healthy bones, proper nerve signaling, muscle function, and blood clotting.
The intact PTH test measures the biologically active form of the hormone in the blood and is an important tool for evaluating calcium metabolism disorders. Elevated PTH levels can indicate hyperparathyroidism, often associated with bone loss and kidney stones, while low levels may signal hypoparathyroidism, which can cause muscle cramps, tingling, and low calcium symptoms. Interpreting PTH alongside calcium, phosphorus, and vitamin D levels helps guide diagnosis and management of conditions affecting bone and mineral health.

Statement on Medical Necessity
All ordered tests should be medically necessary for the diagnosis or detection of disease, illness, impairment, symptom, syndrome, or disorder and the results should be used in the medical management and treatment decisions for the patient. Solaris requires ICD-10 codes with each order for lab testing and both the tests ordered and the diagnosis should be documented in the provider’s medical record for the patient. The United States Department of Health and Human Services, Office of Inspector General, takes the position that a provider who orders medically unnecessary tests may be subject to civil penalties.
Panels and Profiles
Solaris offers Providers the convenience of ordering test combinations in a group at times with the flexibility to choose appropriate test(s) for individual patients. Providers should only order those tests that he or she believes are medically necessary for each patient, and a lesser inclusive profile or individual tests should be ordered if not all tests in the test combination/profile are medically necessary. All tests offered in a test combination/profile may be ordered separately as individual tests. Solaris encourages clients to contact their Solaris representative if the testing configurations shown do not meet individual needs for any reason, or if some other combination of procedures is needed.

CPT Codes listed are in accordance with Current Procedural Terminology, a publication of the American Medical Association.
