Flesherton, ON – I use a great app on my iPhone called Heath Gear to track my blood work. It is nice to be able to graph my TSH, T4, T3 (I have thyroid issues) as well as blood sugar, cholesterol and other blood results in one place. Previously, I would leaf through my paperwork to try to compare and look for improvements/trends in my results. Now I can just click on a test and see the results chronologically. It has positively impacted my health through better tracking!
