Bone mineral density testing (specifically a densitometry or DEXA scan) measures how much bone you have. This test has become the gold standard for osteoporosis evaluation. For specific information on such testing, see bone density test. A spine C...

The word osteoporosis literally means "porous bones." It occurs when bones lose an excessive amount of their protein and mineral content, particularly calcium . Over time, bone mass, and therefore bone strength, is decreased. As a result, bones be...

Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissues, leading to bone fragility and, consequently, an increase in fracture risk.

Alkaline phosphatase (ALP) is a protein found in all body tissues. Tissues with particularly high amounts of ALP include the liver, bile ducts, and bone. A blood test can be done to measure the level of ALP. See also: ALP isoenzyme test

Alkaline phosphatase is an enzyme found throughout the body. Like all enzymes, it is needed, in small amounts, to trigger specific chemical reactions.

A bone density study helps diagnose osteoporosis (bone thinning). Scans of your lower back, hip, or forearm are taken to measure the amount of calcium (density) in your bones. Calcium is the mineral that makes up your bones.

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.

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 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.

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 measure of the amount of vitamin D in the body. In the kidney, 25-hydroxy vitamin D changes into an active form (called 1,25-dihydroxy vitamin D. The active form helps control blood levels of calcium and phosphate. This article discusses the blood test used to measure the amount of 25-hydroxy vitamin D.

Bone radiography is a way to take pictures of bones. Low dose radiation (x-rays) is passed through the body, producing images of the bones on film.
