I’ve made this point before about lab results, but it bears repeating.
Let’s say just for the sake of discussion that your personal blood sugar target is 95 or less. Does that mean that you’re in great shape at 94 but in serious danger at 96? Obviously not.
Laboratory results work the same way. The reference ranges are not lines in the sand such that one side of the line is good and the other is bad. They’re points on a bell curve, or continuum, and they’re based on averages. You don’t suddenly fall off a cliff if a number is .1 over what it’s “supposed” to be. Add to that the fact that each person’s physiology is distinct and invidividual, and what is a problem number for one person can be perfectly okay and tolerable for someone else. And add to that the fact that labs aren’t perfect; on rare occasions one will report an outlier number so anomalous that a retest is called for to make certain the result is trustworthy.
Lab results are seldom black-and-white signposts. They need to be interpreted with judgement and in context with everything else that’s going on. That judgement is part of what doctors acquire by training and experience.
If this were me, I would wait for the next test before forming any definite conclusions. In the meantime, keep doing what you’re doing to maintain good BG control. You’d do that anyway.
