Osteoporosis

Osteoporosis is a condition where bones become weak and break more easily—often after a minor fall or even a cough. Bone loss accelerates with agingmenopause, certain medications (e.g., long-term steroids), and medical conditionsthat affect hormones or nutrient absorption. While diagnosis relies on bone density imaging (DXA)blood and urine tests are essential to evaluate osteoporosis risk, bone metabolism, and secondary causes (issues that make bones lose mineral faster than expected).

Early Intervention can Slow Osteoporosis. Get the Information you Need With an Osteoporosis Test.

Osteoporosis is a common condition that afflicts millions of Americans each year. If undetected, osteoporosis can make sufferers more susceptible to debilitating bone fractures. Early diagnostic testing can enable individuals to take steps to manage their osteoporosis, potentially reducing the rate of decline. 

Here we look at what osteoporosis is, alongside consideration of the lab tests that can be used to diagnose it.

What is Osteoporosis?

Osteoporosis is the process of reducing bone density. Osteoporosis can occur in any bone in the body. For a variety of reasons (some of which are discussed below), the normal reabsorption of bone cells by osteoclasts (specialist cells) isn't matched by the production of fresh bone cells from osteoblasts. The result is a net reduction in bone density.
