Function Health is a great tool to monitor your health, especially as you grow older and/or have issues that need to be monitored. I am a gastric bypass patient that had surgery 32 years ago. The tests for my HDL, LDL, Triglycerides are important to me, as are my iron levels and heart data. I use Function Health results to compare against previous tests and see what has changed and/or can be changed to maintain a healthy lifestyle. I recommend this to everyone.
