PTH Antibody Blood Test

What is the purpose of this test?

The PTH (Parathyroid Hormone) Antibody Blood Test measures the levels of antibodies that target parathyroid hormone (PTH) in your blood. PTH is a hormone produced by the parathyroid glands, which are four small glands located in your neck behind the thyroid gland. This hormone plays a critical role in regulating calcium and phosphorus levels in your blood and bones. Antibodies to PTH can sometimes form when the immune system mistakenly targets the parathyroid hormone, which may affect calcium balance in your body. Measuring these antibodies helps identify conditions that could interfere with normal parathyroid function, such as autoimmune diseases or certain hormonal imbalances.

This test is particularly useful for detecting autoimmune-related conditions that may affect the parathyroid glands or cause abnormal calcium levels. High or low calcium levels can lead to issues like bone weakness, kidney problems, muscle cramps, or fatigue. By identifying PTH antibodies, healthcare providers can better understand if your symptoms are linked to an immune response targeting PTH. Early detection can help prevent further complications and guide appropriate treatment plans.

Who should get this test?

• Individuals with symptoms of abnormal calcium levels, such as muscle cramps, fatigue, or bone pain.
• People with a family history of parathyroid or autoimmune disorders.
• Individuals who have been diagnosed with hyperparathyroidism or hypoparathyroidism.
• Those experiencing unexplained kidney stones or bone weakness.
• People with abnormal results from previous calcium or parathyroid hormone tests.

When should I order the PTH Antibody Blood Test?

Individuals may consider ordering this test if they have symptoms or exposure concerns related to abnormal parathyroid function. Symptoms to consider:

• Muscle cramps, spasms, or tingling in the hands, feet, or face.
• Fatigue, weakness, or lack of energy.
• Bone pain or frequent fractures.
• Unexplained kidney stones or kidney problems.
• Difficulty concentrating or memory issues.
• Nausea, stomach pain, or poor appetite.

If you have these symptoms or suspect an issue with your parathyroid function, the PTH Antibody Blood Test can provide helpful information to guide you and your doctor in managing your health and addressing underlying conditions.
