“A1c: Also known as Hb1c or hemoglobin A1c, this is a test that is conducted every 3 months (or as requested) by an endocrinologist. A patient gets blood drawn to determine the average amount of glucose concentration in the blood during that 3 month period. The result of this test is a percentage amount, with 5% being an average result for a non-diabetic individual.”
This is the definition of A1c that I’ve shared in the diabetes dictionary section of Hugging the Cactus, and while of course the meaning and purpose of an A1c test will never change, one thing certainly has – and that’s the question of whether or not it’s the gold standard metric that indicates diabetes management.
That’s because A1c has a little competition called time in range. The concept is exactly what it sounds like: It’s an indicator of the amount of time a person with diabetes has their blood sugar within their preferred range, and it can best be captured by a percentage (e.g., I spent 70% of my day yesterday in range, with 30% of my readings either lower or higher than my ideal range).
While these two metrics vary from one another in how they are captured and analyzed, they do have one thing in common for a person with diabetes…is it a data point to share with others outside your healthcare team, or is it something to keep to yourself?
To share or not to share A1c and/or time in range…that is, indeed, the question.

The answer is personal and unique to every individual with diabetes, and for me, I keep it to myself in both cases. I’ve never felt comfortable opening up about my A1c or time in range online or in person. I think that’s mostly because I struggle with comparing myself to others. I do my best not to, but I can definitely turn diabetes into a competition that I internalize at all costs because I don’t want other people to know that sharing about these data points makes me deeply uncomfortable.
It’s how I am, how I’ve always been, and likely how I’ll be for quite some time. I’m curious to discover whether or not starting the Omnipod 5 will impact that at all, seeing as I have high hopes that the system will greatly increase my time spent in range as well as lower my A1c. But for now, I’m content with keeping these diabetes numbers to myself, and will aim to get better about telling people that I prefer not to discuss either.
