There are also blood tests for your vitamin values. With a blood test check up, you can have your cholesterol values specifically tested and if the results are good, you will be motivated to continue. Have the cholesterol values become lower after a few weeks or months? You can only see this with a blood test. Have you changed your behaviour pattern recently? Have you started eating less sugar and less fat, for example, because you have high cholesterol? After some time, of course, you want to know if you have made progress.
