A Parathyroid Hormone (PTH) test is a blood test that measures the level of parathyroid hormone in your body. This hormone, produced by the parathyroid glands, plays a vital role in regulating calcium and phosphorus levels in your bones and blood.
The PTH test is often ordered by doctors to help diagnose and monitor conditions related to parathyroid gland function. These conditions can include hyperparathyroidism, hypoparathyroidism, and certain types of bone diseases. Hyperparathyroidism occurs when the parathyroid glands produce too much PTH, causing high calcium and low phosphorus levels in the blood. Hypoparathyroidism, on the other hand, is characterized by low PTH levels and can lead to low calcium and high phosphorus levels.
Having a PTH test can be a simple procedure, similar to a routine blood test. A healthcare provider will usually draw a small sample of your blood using a needle, usually from a vein in your arm. The sample is then sent to a laboratory for analysis. Results are typically available within a few days.
Understanding your PTH test results can mean a lot for your healthcare. Abnormal results could indicate an underlying condition that requires further evaluation and care. It’s important to discuss your results with your healthcare provider, who can explain what they mean in the context of your overall health.
What is it used for
The Parathyroid Hormone (PTH) test is commonly used to diagnose and monitor conditions related to the parathyroid glands. These glands are located in the neck and produce PTH, a hormone that plays a vital role in regulating calcium and phosphorus levels in the body.
The PTH test is usually ordered when a person is experiencing symptoms related to abnormal calcium levels, such as muscle weakness, fatigue, or bone pain. It is also used to evaluate the function of the parathyroid glands in individuals who have had surgery on their neck or who have a history of calcium imbalances.

Monitoring PTH levels can be particularly important for individuals with kidney disease, as their kidneys may not be able to process and excrete phosphorus properly. High levels of PTH can signify that the body is trying to compensate for the excess phosphorus by breaking down bone tissue, which can lead to weakened bones and an increased risk of fractures.
The PTH test is a simple blood test that requires a little needle to collect a small amount of blood. The blood sample is then sent to a laboratory for analysis. The results of the test can provide valuable information about a person’s bone health and the function of their parathyroid glands.
Why do I need a PTH test
Having a little too much or too little parathyroid hormone (PTH) in your body can cause health problems. PTH helps control the levels of calcium and phosphorus in your blood. If you have too much PTH, it can cause your blood calcium levels to be higher than normal. This can lead to the formation of calcium deposits in your organs and tissues, such as your kidneys or blood vessels. It can also cause your bones to lose calcium, making them weak and brittle.
On the other hand, if you have too little PTH, it can cause your blood calcium levels to be lower than normal. This can result in muscle cramps, numbness or tingling in your fingers and lips, and even seizures. Low PTH levels may also mean that your body cannot properly absorb or use calcium, which is necessary for strong bones and teeth.
A PTH test is done to measure the amount of PTH in your blood. It helps your doctor evaluate your calcium and phosphorus levels, and determine if there are any issues with your parathyroid glands. If you are experiencing symptoms such as bone pain, frequent fractures, kidney stones, or abnormal levels of calcium in your blood, your doctor may recommend a PTH test to diagnose and monitor conditions such as hyperparathyroidism or hypoparathyroidism.
Understanding your PTH levels can help your healthcare provider determine the best course of care for you. Whether it means you need treatment to correct high PTH levels or adjustments to your calcium or vitamin D intake, a PTH test can provide valuable information about your bone health and overall well-being.
What happens during a PTH test
A PTH test is a simple blood test that measures the levels of parathyroid hormone in your blood. This hormone is produced by the parathyroid glands, which are located in your neck. The PTH test is usually performed to assess the functioning of these glands and to diagnose conditions related to calcium and phosphorus levels in your body.
When you arrive for the test, a healthcare professional will guide you through the procedure. They will clean the area where the needle will be inserted, typically on the inside of your arm. The use of alcohol or another appropriate cleaning agent ensures that the area is germ-free and reduces the risk of infection.
Once the area is cleaned, the healthcare professional will use a small needle to draw a sample of your blood. The process may involve a little discomfort, but it is generally well-tolerated by most people. If you are anxious about having blood drawn, it may help to take slow, deep breaths and try to relax during the procedure.
After the blood sample is collected, the healthcare professional will apply pressure and a bandage to the puncture site to prevent bleeding. You may be advised to keep the bandage in place for a few minutes while the puncture site heals.
It is important to note that the PTH test only takes a few minutes to complete. After the test, you can resume your normal activities and return to your usual care routine.
Will I need to do anything to prepare for the test
Before having a Parathyroid Hormone (PTH) test, there are a few things you should know and do:
1. Fasting:
In most cases, you will not need to fast before the test. This means that you can have your regular meals and beverages as usual. However, your healthcare provider may instruct you to fast for a certain period of time, especially if other tests are being done along with the PTH test. If fasting is required, it is important to follow these instructions carefully.
2. Medications:
Inform your doctor about any medications you are currently taking, including prescription drugs, over-the-counter medications, and supplements. Some medications can affect the results of the PTH test. Your healthcare provider may ask you to temporarily stop taking certain medications before the test.
Note: Do not stop or adjust your medications without consulting your healthcare provider.
3. Other Tests:
If you are scheduled to have other blood tests on the same day as the PTH test, it is generally recommended to have the PTH test done before any other blood tests. This is because the procedure for the PTH test involves a needle prick, and having blood drawn from the same arm multiple times can cause discomfort and bruising.
Remember: Follow any specific instructions given by your healthcare provider to ensure accurate and reliable test results.
If you have any concerns or questions about the PTH test or its preparation, it’s important to communicate with your doctor. They can provide you with the necessary information and address any concerns you may have. Taking proper care and following the instructions will help ensure an optimal testing experience.
Are there any risks to the test
Generally, the parathyroid hormone (PTH) test is a safe procedure with minimal risks. However, there are a few things that you should be aware of:
Phosphorus Imbalance:
The hormone being tested, PTH, plays a crucial role in regulating phosphorus levels in the body. If the test reveals abnormal PTH levels, it may indicate an imbalance in phosphorus levels. This could mean that you have too much or too little phosphorus in your blood, which may require further medical care and treatment.
Discomfort during the test:
While the PTH test itself is relatively painless, you may experience a slight discomfort or mild pain when the needle is inserted into your arm to draw a blood sample. This discomfort is typically temporary and goes away quickly.
It’s important to note that the risks associated with the PTH test are minimal compared to the valuable information it provides about your bone and mineral health. If you have any concerns or questions about the risks or procedures, it is best to consult with your healthcare provider beforehand.
What do the results mean
After having a Parathyroid Hormone (PTH) test, the results can provide important information about the health of your parathyroid glands and the balance of calcium and phosphorus in your body.
A normal PTH level usually means that your parathyroid glands are working properly to regulate the levels of calcium and phosphorus in your blood. This is important for the health and functioning of your bones, muscles, and nerves.
If your PTH level is low, it may indicate that you have hypoparathyroidism, a condition where the parathyroid glands do not produce enough PTH. This can lead to low levels of calcium in your blood, which can cause symptoms such as muscle cramps, tingling or numbness in the extremities, and even seizures.
On the other hand, if your PTH level is high, it may indicate that you have hyperparathyroidism, a condition where the parathyroid glands produce too much PTH. This can lead to high levels of calcium in your blood, which can affect the health of your bones, kidneys, and other organs.
It’s important to note that the PTH test is just one piece of the puzzle when it comes to diagnosing parathyroid disorders. Your doctor will also consider other factors such as your symptoms, medical history, and the results of other tests. If your PTH levels are abnormal, your doctor may recommend further testing to determine the underlying cause.
Remember that interpreting the results of any medical test should always be done in consultation with a healthcare professional. They will be able to provide you with personalized care and guidance based on your specific situation.
Is there anything else I need to know about a PTH test
When you take a PTH test, a small needle is used to draw blood from a vein in your arm. You may feel a slight pinch or prick when the needle is inserted, but it is usually not painful. The blood sample is then sent to a laboratory for analysis.
The PTH test measures the level of parathyroid hormone in your blood. This hormone helps regulate the amount of calcium and phosphorus in your body. It accomplishes this by signaling the bones to release calcium and increases the absorption of phosphorus from the intestines.
A high PTH level may indicate that you have hyperparathyroidism, a condition where the parathyroid glands produce too much hormone. This can lead to high calcium levels in the blood and can cause problems like kidney stones, bone pain, and weakened bones.
On the other hand, a low PTH level may mean that you have hypoparathyroidism, a condition where the parathyroid glands do not produce enough hormone. This can lead to low calcium and phosphorus levels in the blood, which can cause muscle cramps, numbness or tingling in the hands and feet, and seizures.
If you are having a PTH test, it is important to follow any instructions your healthcare provider gives you. They may ask you to fast for a certain period of time before the test or avoid certain medications that could affect the results. Taking these steps can help ensure that your test is accurate and that you receive the best care possible.
