Bone density testing is a method used to measure the density of your bones, helping to assess the health of your skeleton. Typically, this test is conducted using a device called a DEXA (Dual-Energy X-ray Absorptiometry) scanner. The procedure is quite simple: you lie down on a table, and the machine sends a small amount of X-rays through your body. By measuring how much of these X-rays are absorbed by your bones, the device calculates your bone density. The whole process takes about 10 to 20 minutes and is painless and safe. Regular bone density testing can help detect osteoporosis early, allowing for timely preventive and therapeutic measures.
