The condition, osteopenia, is identified by low bone mineral density and can lead to osteoporosis as one ages. Bone mineral density peaks before the age of 30, after which it slowly decreases. Osteopenia is diagnosed by a DXA (Dual-energy X-ray absorptiometry) scan which measures bone mineral density. This provides a T Score, which is the measurement used to assist in determining whether or not an individual has osteopenia or osteoporosis.
