 During test day one or test day two, each subject will have a Dual Energy X-ray Absorptiometer DEXA scan and a Peripheral Quantitative Computer Tomography pQCT scan performed on them The DEXA is to assess bone mineral density BMD, body fat percentage and lean tissue. The pQCT will assess bone strength at the radius and tibia. For The DEXA, the subject will remove any items that may contain metal - including jewelry, belts, shoes and piercings. A gown will be provided if needed. The subject will lie on a table for approximately 6 minutes, while the table rotates and a mechanical arm moves above the subject body measuring for the BMI. For the pQCT, the subject will be seated and position their forearm into the pQCT device and remain still for 3-5 minutes. They will then place their lower leg into the same device for another 3-5 minutes to be scanned. If the subject is female, a pregnancy test will be performed before any testing begins for each testing visit in order to confirm the subject is not pregnant.
