What it means
A1c is the share of your hemoglobin with sugar stuck to it, an average of the last few months that leans on the latest weeks. Under 5.7% is normal, 5.7 to 6.4% (39 to 47 mmol/mol) is the prediabetes range, and 6.5% (48) or more is the diabetes range. 6.1% sits 0.4 points under the diabetes line, and 0.5 points from normal. It fits an average glucose anywhere from 102 to 155 mg/dL.
Can this number decide it?
Only a certified lab A1c decides a band, and a diagnosis takes two results unless the number is clearly high. A home kit can only tell you to get a lab test. Anemia, sickle cell trait and some other blood conditions can throw A1c off, so pair it with a fasting glucose.
What to do
Repeat it at a lab with an A1c. If it holds, the plan that cut new diabetes by 58% in the biggest trial is to lose 5 to 7% of your weight if you carry extra, walk 150 minutes a week with 10 minutes after meals, and retest in 12 weeks. Work out your plan.
When to get help now
Call 911 or go to the ER if a blood sugar stays at 300 or more, or comes with vomiting so you can't keep fluids down, fruity breath or hard breathing. Under 70 with confusion, fainting or trouble swallowing is an emergency too. Pregnancy uses tighter numbers, so take any number to your midwife or doctor, and if you take insulin or a sulfonylurea, your targets come from your prescriber.
