Serum, NA, Fasting or Non Fasting: As suggested by doctor
The iPTH test requires a blood sample. Your blood will be drawn from a vein in your arm by a healthcare provider.
The turnaround time for the iPTH test can vary between laboratories, but results are typically available within a few days.
Test Normal Range:
The normal range for intact parathyroid hormone (iPTH) levels can vary depending on the laboratory and the units of measurement used. It is critical to evaluate the results in the context of the laboratory’s specific reference range.
What is the Test?
The iPTH test measures the concentration of intact parathyroid hormone in your blood. Parathyroid hormone is produced by the parathyroid glands, which are located in the neck. This hormone plays a critical role in regulating calcium and phosphate levels in the body. It helps maintain the balance of these minerals in the blood and bones.
A healthcare provider will draw a blood sample from a vein in your arm. A blood sample is sent to a laboratory for analysis. The blood sample is processed in the laboratory, and the concentration of iPTH is determined using specialist equipment and processes.
When to Take the Test:
When there is a clinical suspicion of parathyroid gland malfunction, such as hyperparathyroidism or hypoparathyroidism, the iPTH test is usually administered. It is used to assess parathyroid function and calcium regulation.
Who Should Take This Test:
This test is ordered for individuals with symptoms of parathyroid disorders, abnormal calcium or phosphate levels, or as part of the evaluation of bone disorders. It may also be used to monitor individuals with known parathyroid conditions.
Precautions for Exceptional Cases (Pregnancy, etc.):
Pregnancy can affect parathyroid hormone levels, so healthcare providers consider individual circumstances when interpreting results during pregnancy. It’s essential to discuss any special considerations with your healthcare provider.
FAQs (Frequently Asked Questions):
Q1: What does a high iPTH level indicate?
A: Elevated iPTH levels may suggest primary hyperparathyroidism, a condition where the parathyroid glands produce too much hormone, leading to increased calcium levels in the blood.
Q2: What does a low iPTH level indicate?
A: Low iPTH levels may be seen in hypoparathyroidism, a condition where the parathyroid glands do not produce enough hormone, resulting in low calcium levels.
Q3: Are there any specific symptoms of parathyroid disorders?
A: Symptoms may include fatigue, weakness, bone pain, kidney stones, and disturbances in calcium and phosphate levels.
Q4: Can medications or other medical conditions affect iPTH levels?
A: Yes, certain medications and underlying medical conditions can influence iPTH levels. It’s important to inform your healthcare provider about your medical history and medications.
Q5: How is primary hyperparathyroidism treated?
A: Treatment options for primary hyperparathyroidism may include surgery to remove the overactive parathyroid gland(s) or conservative management, depending on the severity of the condition. Your healthcare provider will select the best course of action.
