📌 What is the iPTH Test?
A blood test that measures levels of intact parathyroid hormone (PTH), which regulates calcium, phosphorus, and vitamin D levels in the body.
Helps assess parathyroid gland function and diagnose conditions related to calcium imbalances.
🎯 Purpose of the Test
✅ Diagnoses hyperparathyroidism (overactive parathyroid glands).
✅ Identifies hypoparathyroidism (underactive parathyroid glands).
✅ Evaluates calcium imbalances, including high or low calcium levels.
✅ Monitors patients with chronic kidney disease (CKD), as kidney function affects PTH regulation.
📊 Normal Ranges
🔹 Normal iPTH Levels: 10 - 65 pg/mL (May vary by laboratory methods.)
🔹 High iPTH Levels: May indicate hyperparathyroidism, vitamin D deficiency, kidney disease, or calcium imbalance.
🔹 Low iPTH Levels: May suggest hypoparathyroidism, excess calcium intake, or autoimmune conditions.
📝 Test Procedure
1️⃣ A blood sample is drawn, usually from a vein in the arm.
2️⃣ The sample is analyzed using immunoassay techniques to measure iPTH levels.
3️⃣ Results help in diagnosing and managing parathyroid-related disorders.
⚠️ Who Should Get Tested?
🔹 Individuals with abnormal calcium levels (high or low).
🔹 Patients with kidney disease, as CKD affects PTH regulation.
🔹 Those with bone disorders, osteoporosis, or frequent fractures.
🔹 People experiencing muscle weakness, fatigue, kidney stones, or unexplained tingling/numbness.
✅ Why is This Test Important?
✔️ Early detection of parathyroid and calcium-related disorders.
✔️ Helps prevent complications like osteoporosis and kidney stones.
✔️ Guides treatment decisions for kidney disease and metabolic disorders.
