The cost might either be attributed to the labor or the test itself, but if it’s the labor, then those are really precious seconds needed to take that vial of blood. Having a regular blood test is considered as one of the most important ways to keep track of your overall physical health as it allows you to see how your body changes over time and makes it possible for you to make informed decisions about your health. The most common tests are complete blood count (CBC), chemistry (basic metabolic) panel, thyroid panel, nutrient tests, enzyme markers, or sexually transmitted diseases (STD). Because what you eat or drink contains vitamins, proteins, and other nutrients that can cause the related levels in your blood to spike or drop, fasting for 8–12 hours is needed to ensure that blood test results are free from these factors.
