A DEXA scan has a very low error rate of 1-2%, compared to 5-15% for most methods. This is due to the advanced X-ray technology that leave little guesswork and no extra calculations to provide accurate data.Furthermore, which is the most accurate test to measure body fat?
DEXA / DXA Scan is widely considered as one of the most accurate and comprehensive body composition tests. The DEXA scan utilizes dual-energy X-ray absorptiometry (DXA). The test looks beyond your weight and the traditional body mass index (BMI).
Also, can a DEXA scan be wrong? Because the threshold for density-based osteoporosis is low, many women who fail DEXA tests will never fracture. As many as half of all American women age 50 or older could be “diagnosed” with osteopenia based on DEXA scans' assessment of bone density.

While you can never regain the bone density you had in your youth, you can help prevent rapidly thinning bones, even after your diagnosis. Here's a breakdown of five lifestyle steps to help you on the road to better bone health.Can a DEXA scan show bone cancer?
A DEXA scan measures bone mineral density. This scan also may help detect whether cancer has metastasized, or spread, to the bones. Using low levels of X-rays to measure bone mineral density, the DEXA scan examines the entire skeleton or specific points on the body, such as the spine or hip.What is a good DEXA scan score?
DXA Scan Results T-score of -1.0 or above = normal bone density. T-score between -1.0 and -2.5 = low bone density, or osteopenia. T-score of -2.5 or lower = osteoporosis.Can I exercise before a DEXA scan?
