Results are shared by your healthcare provider.

Parathyroid Hormone Test Result

Here is basic meaning of Parathyroid Hormone Test.

Elevated PTH levels may indicate hyperparathyroidism, an overactive parathyroid gland.
Low PTH levels can suggest hypoparathyroidism, an underactive parathyroid gland.
Normal results fall within a specific reference range.
Consult your healthcare provider to understand your specific results and discuss any necessary follow-up steps.

Parathyroid Hormone Test Normal Range

Here is the normal range of the Parathyroid Hormone Test.

Parathyroid Hormone Test	Normal Range
PTH Level	10-65 pg/mL

Parathyroid Hormone Test Interpretation

Here is the Interpretation of the Parathyroid Hormone Test.

PTH Level (pg/mL)	Interpretation
10 to 65	Within Normal Limits
Above 65	Elevated (High) PTH levels may indicate hyperparathyroidism, vitamin D disorders, or other health issues.
Below 10	Reduced (Low) PTH levels can be associated with conditions like hypoparathyroidism, hypercalcemia, or parathyroid gland injury.

Parathyroid Hormone Test High Levels

Here are the potential causes of Parathyroid Hormone Test High Levels.

Potential Causes	Information
Hyperparathyroidism	Overactivity of the parathyroid glands, often due to a benign tumor, leading to excessive PTH production.
Vitamin D Disorders	Abnormal vitamin D metabolism can stimulate PTH production.
Kidney Function Issues	Kidney disease can lead to mineral imbalances and increased PTH levels.
Parathyroid Tumors	Noncancerous tumors in the parathyroid glands can result in high PTH levels.
Pseudohypoparathyroidism	A condition where the body fails to respond appropriately to PTH.

Parathyroid Hormone Test Low Levels

Here are the potential causes of Parathyroid Hormone Test Low Levels.

Potential Causes	Information
Hypoparathyroidism	Reduced function or removal of the parathyroid glands can result in low PTH levels.
Parathyroid Gland Injury	Surgical procedures or radiation therapy may damage the parathyroid glands.
Autoimmune Disorders	Conditions that damage the parathyroid glands can lead to decreased PTH production.
Cancers Affecting Bone	Some cancers that have spread to the bone may affect PTH levels.
Excess Calcium Intake	Consuming too much calcium through supplements or antacids can suppress PTH production.
Vitamin D Overdose	Excessive vitamin D intake can lead to low PTH levels.

Specimen Requirements For Parathyroid Hormone Test

Here are the specimen requirements for the Parathyroid Hormone Test.

Specimen Type	Blood (Venous)
Volume	3-5 mL of blood
Container	Sterile blood collection tube (lavender top or EDTA anticoagulant)
Collection	Venipuncture by a healthcare professional. Invert the tube several times to mix the anticoagulant.
Storage	Store at room temperature (RT) and deliver to the laboratory promptly.
Sample Stability	Short-term (hours)
Causes for Rejection	Hemolysis, clotted sample, insufficient volume, incorrect container (non-sterile).

Parathyroid Hormone Test is Safe?

Parathyroid Hormone Test is Safe blood test with minimal risks.

Risks are associated with the blood draw.
Benefits usually outweigh the potential risks in assessing parathyroid function.

When Do You Get Parathyroid Hormone Test Results?

PTH test results are usually available within a few days.
The exact reporting time may vary depending on the laboratory and healthcare provider.

Parathyroid Hormone Test Limitation

Here is the basic limitation of Parathyroid Hormone Test.

Results may be influenced by factors like calcium intake, kidney function, and medications.
PTH levels can vary throughout the day, affecting test accuracy.
The test provides information about PTH levels but not the underlying cause of parathyroid dysfunction.
Interpretation may require consideration of other blood and medical tests.
Abnormal results may necessitate further investigation to determine the cause.

Parathyroid Hormone Test Risk Factors

Here are some of the risk factors of the Parathyroid Hormone Test.

Influence of factors like calcium intake, kidney function, and medications on test results.
Variability in PTH levels throughout the day.
Interpretation may require consideration of other blood and medical tests.

FAQ

What is a Parathyroid Hormone (PTH) test?

A Parathyroid Hormone (PTH) test is a blood test that measures the level of PTH in your bloodstream. PTH is a hormone produced by the parathyroid glands, which are located in the neck. It plays a crucial role in regulating calcium levels in the body. This test is often used to diagnose and monitor conditions related to calcium metabolism, such as hyperparathyroidism or hypoparathyroidism.

Why is the PTH test important?

The PTH test is important because it helps assess the functioning of your parathyroid glands and the balance of calcium in your body. Abnormal PTH levels can indicate various medical conditions, including primary hyperparathyroidism (excess PTH production), secondary hyperparathyroidism (response to low calcium levels), or hypoparathyroidism (insufficient PTH production). Early detection and monitoring of these conditions are vital for proper management and treatment.

When should I get a PTH test?

Your doctor may recommend a PTH test if you exhibit symptoms of hypercalcemia (high blood calcium) or hypocalcemia (low blood calcium). Symptoms may include muscle weakness, bone pain, kidney stones, and more. Additionally, the test is performed in cases of suspected parathyroid disorders, osteoporosis, or as part of routine health assessments.

What do PTH test results indicate?

PTH test results are typically reported as the concentration of PTH in your blood. High PTH levels can suggest hyperparathyroidism, whereas low levels may indicate hypoparathyroidism. Your doctor will interpret the results alongside other tests and your medical history to determine the underlying cause and recommend appropriate treatment.
