For medical UA's for insurance companies ALWAYS use a synthetic urine. This is one of the main reasons Spectrum Labs markets theres. Its none of the insurance companies business what existing conditions you might or might not have. They use it so they don't have to cover any pre-existing condition you have. Why would you want medical insurance if they don't cover whats wrong with you? I would like to see a small sticky educating people about the perils of using your own urine for insurance purposes.
Only your Dr. needs those results.
