Lack in vitamin D reduces the absorption of calcium in the body, accelerates bone loss and may increase the risk of fractures due to osteoporosis. An algorithm that will allow immediate and non-invasive quantification of vitamin D levels will shorten the time of diagnosis, reduce lab costs and prevent hazards or discomfort to the patient associated with a blood test.

The goal of the study is therefore to develop a non-invasive method for quantifying vitamin D levels in the body using spectroscopy.

40 subjects will be recruited: 20 hospitalized patients in the rehabilitation department, diagnosed with osteoporosis and 20 healthy subjects. Spectroscopy will be used with visible light on the subject's skin and middle infrared (MIR) on the blood sample to find correlation with the chemical lab test results.
