HbA1c
Also known as Glycated Hemoglobin
What it is
HbA1c reflects your average blood sugar level over the preceding two to three months, based on how much glucose has attached itself to the hemoglobin in your red blood cells.
Why it matters
Because red blood cells live for about three months, HbA1c smooths out the day-to-day swings a single glucose reading can't, which is why it's the standard marker used to identify prediabetes and diabetes and to monitor blood sugar control over time. It's one of the threshold markers in Zaro's Surface panel: a value is either inside a normal range or it isn't, and by the time it crosses that line, elevated blood sugar has typically been present for a while already, which is exactly why pairing it with an earlier-warning marker like fasting insulin matters.
HbA1c is one of the markers in Zaro's Surface panel and every tier above it.
