Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A blood sample is required for the Parathyroid Hormone (PTH) test. Typically, this sample is taken from a vein in your arm.
Test Time:
The results of the PTH test are usually available within a day or two after the blood sample is collected.
Test Normal Range:
The normal range for parathyroid hormone (PTH) in the blood can vary depending on the laboratory and the specific assay used. Typically, normal PTH levels are between 10 and 65 picograms per milliliter (pg/mL).
What is the Test?
The PTH test measures the level of parathyroid hormone in your blood. Parathyroid hormone is produced by the parathyroid glands, which are four small glands located near the thyroid gland in your neck. PTH plays a crucial role in regulating calcium levels in your body.
Test Procedure:
A medical professional will clean the area around a vein in your arm. To get a blood sample, a needle will be placed into the vein. The blood sample will be collected into a tube. The material will be analyzed in a laboratory.
When to Take the Test:
The PTH test is often ordered when there is suspicion of a parathyroid disorder, such as hyperparathyroidism or hypoparathyroidism. It may also be ordered if you have symptoms related to abnormal calcium levels.
Who Should Take This Test:
Individuals who have symptoms of a parathyroid disorder, such as excessive fatigue, muscle weakness, bone pain, kidney stones, or abnormal calcium levels in the blood, may undergo this test.
Precautions for Exceptional Cases (Pregnancy, etc.):
Generally, the PTH test is safe for pregnant individuals. However, if you are pregnant or have any specific concerns, it’s important to discuss them with your healthcare provider before the test.
FAQs (Frequently Asked Questions):
Q1: What are the parathyroid glands, and what is their function?
A: The parathyroid glands are small glands located near the thyroid gland. They produce parathyroid hormone (PTH), which helps regulate calcium levels in the blood and bone.
Q2: What does it mean if my PTH levels are too high?
A: Elevated PTH levels can indicate hyperparathyroidism, a condition where the parathyroid glands produce too much PTH. This can lead to increased calcium levels in the blood, potentially causing kidney stones and weakening bones.
Q3: What does it mean if my PTH levels are too low?
A: Low PTH levels can indicate hypoparathyroidism, a condition where the parathyroid glands produce too little PTH. This can lead to low calcium levels in the blood, resulting in muscle cramps, numbness, and other symptoms.
Q4: How is hyperparathyroidism treated?
A: Treatment depends on the underlying cause but may involve surgery to remove overactive parathyroid tissue or medication to control calcium levels.
Q5: Can I eat or drink before a PTH test?
A: Fasting is usually not required before a PTH test. However, your healthcare provider will provide specific instructions if fasting or any other special preparations are necessary for your test.
