You may have experienced this scenario before: your physician orders a blood test for you, you go to the lab to have your blood drawn, then you receive a call from the nurse stating that your labs were normal. You feel good about that and continue on with your day. While the nurse may not have stated anything inaccurately, you may want to know more than that and here's why. Normal labs are defined by a range determined by the specific laboratory you used. For instance, a normal blood glucose may be defined as any value between 75-100 in the lab. However, if you typically run 75 in a fasting state, and now suddenly you are running 90-100, you may want to know that and determine the cause. Are you consuming more sugary foods? Are you taking a medication that can cause that, such as a steroid? Determining the cause can then help you avoid moving into the pre-diabetic category and eventually into the diabetic category. A similar example I share in the video below is the lab associated with platelets. I strongly recommend that you keep organized and up-to-date records on your labs so you can track the patterns rather than simply relying on healthcare staff to inform you that everything is normal.
