Endocrine / Hormones
Also known as: parathormone, intact PTH
Symptoms like severe muscle cramps, tingling in fingers/lips, irregular heartbeat, or seizures can indicate extremely low calcium levels and warrant urgent medical attention. Severe fatigue, persistent nausea/vomiting, or confusion with high calcium levels should also be discussed with a clinician promptly.
This test checks how much parathyroid hormone (PTH) is in your blood. PTH is a chemical messenger. Four tiny glands in your neck make it. These glands are called parathyroid glands.
Your doctor orders this test to find out why your blood calcium levels are high or low. It also helps check on people with long-term kidney problems or weak bones. The test shows if treatments for gland problems in your neck are working.
Reference ranges for PTH can vary between different laboratories. Your doctor will interpret your results based on these ranges, your age, other test results (especially calcium), and your overall health.
