Sample Type: Serum
Test Included:
Measurement of parathyroid hormone (PTH) in blood
Sample Required:
Blood sample
Test Time:
Results are typically available within a few days.
Test Range Values:
Normal PTH levels are around 10 to 65 picograms per milliliter (pg/mL)
What is the test?
This test measures the level of PTH, a hormone involved in calcium regulation, in the blood.
Test Procedure:
A blood sample is collected and analyzed in the laboratory to determine PTH levels.
When to take the test:
Useful for evaluating parathyroid function, calcium regulation, or diagnosing conditions like hyperparathyroidism or hypoparathyroidism.
Who should take the test:
Individuals with suspected parathyroid disorders, abnormal calcium levels, or bone-related issues may require this test.
Frequently Asked Questions (FAQs) for Parathyroid Hormone (Fasting):
Q1: Is fasting necessary before getting a parathyroid hormone test?
A: Fasting might not be necessary for this test specifically, but follow any specific instructions provided by your healthcare provider.
Q2: What role does parathyroid hormone play in the body?
A: PTH helps regulate calcium and phosphate levels in the blood, impacting bone health and other physiological functions.
Q3: Can vitamin D levels affect parathyroid hormone levels?
A: Yes, low vitamin D levels can trigger increased PTH secretion to maintain normal calcium levels in the blood.
Q4: What does high or low PTH levels indicate?
A: High levels may suggest hyperparathyroidism or conditions causing excess calcium in the blood, while low levels might indicate hypoparathyroidism or calcium deficiency.
Q5: Are there any medications that can impact PTH levels?
A: Some medications, like calcium supplements or certain diuretics, can influence PTH levels. Inform your healthcare provider about your medications.
