If your results are within normal limits, it’s certainly a good sign. But one set of tests only offers a snapshot of certain aspects of your health. There is a lot of overlap among results from healthy people and those with diseases, so there is still a chance that there could be an undetected problem. If you’re trying to follow a healthy lifestyle, take test results that are within range as a good sign, and keep it up. However, normal results do not mean that unhealthy habits will not have consequences in the future. Your health care provider may suggest monitoring with a series of tests to make sure you’re still on track and to document any trends. A rise or drop in results, even if they are still within normal limits, could provide meaningful information.
