During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

Serum calcium is a laboratory test to measure the amount of calcium in your blood. All cells need calcium in order to work. Calcium helps build strong bones and teeth. It is important for heart function, and helps with muscle contraction, nerve signaling, and blood clotting. Calcium can also be measured in the urine. See: Calcium - urine test

The 25-hydroxy vitamin D test is the most accurate way to measure how much vitamin D is in your body. In the kidney, 25-hydroxy vitamin D changes into an active form of the vitamin. The active form of vitamin D helps control calcium and phosphate levels in the body. This article discusses the blood test used to measure the amount of 25-hydroxy vitamin D.

Ionized calcium is calcium that is freely flowing in your blood and not attached to proteins. It is also called free calcium. All cells need calcium in order to work. Calcium helps build strong bones and teeth. It is important for heart function, and helps with muscle contraction, nerve signaling, and blood clotting. This article discusses the test used to measure the amount of ionized calcium in blood. See also: Serum calcium

PTH stands for parathyroid hormone. It is a protein hormone released by the parathyroid gland. PTH is the most important regulator of the body's calcium and phosphorus levels. Release of PTH is controlled by the level of calcium in the blood. Low blood calcium levels cause increased PTH to be released, while high blood calcium levels inhibit PTH release. A laboratory test can be done to measure the amount of PTH in your blood.

The parathyroid hormone (PTH) test is a blood test performed to determine the serum levels of a hormone secreted by the parathyroid gland in response to low blood calcium levels. PTH works together with vitamin D to maintain healthy bones. The parathyroid glands are small paired glands located near the thyroid gland at the base of the neck.

The parathyroid hormone (PTH) test is a blood test performed to determine the serum levels of a hormone secreted by the parathyroid gland. The parathyroid glands are small paired glands located near the thyroid gland at the base of the neck. Most people have four glands, two on each side of the neck. PTH regulates calcium and phosphorus levels in the body. It is secreted in response to low blood ionized calcium levels, causing bone to release calcium into the blood stream. In addition, it promotes the renal reabsorption of calcium and excretion of phosphorus.
