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