Think your test result is “a bit outside normal”? Or worse, inside the normal range but you still feel awful? Here’s the truth: medical “normal ranges” aren’t universal. They’re based on large population studies, but those groups don’t always represent everyone. Many reference ranges come from samples that may not match your age, sex, ethnicity, body type, or health background. Your hormones, fitness level, lifestyle, and even the time of day can shift what’s normal for your body. That’s why doctors look at trends, your baseline, and your symptoms, not just one number. A slightly abnormal result might be completely fine. And a perfectly normal one might still be a problem for you.
