You just got your lab results back. You see the word HIGH next to a number. Your heart drops. ๐จ But nobody told you what it actually means. Here's the truth โ not every HIGH result means something is wrong. Some numbers go HIGH because of:
โ๏ธ What you ate before the test
โ๏ธ Dehydration
โ๏ธ Physical activity
โ๏ธ Time of day the sample was taken Context matters more than the number. Follow with Isaac โ I break down what your results actually mean, in plain language.
