A peripheral DEXA test, or pDEXA test, is a variation on the Dual-energy X-ray Absorptiometry test, one of the most popular bone-density tests. Instead of using a small amount of x ray to measure bone mass at the hip or the lumbar spine, it tests the forearm, just above the wrist. This test is less expensive than other bone-density measurements but also can help predict a higher risk for fractures in other bones.
