Yes, home A1c tests exist and are widely available online and at some pharmacies. They come in two main formats: mail-in kits where you send a blood sample to a lab, and point-of-care devices that give you a result at home in minutes. Prices typically range from about $50 to $100 per test, and several options carry FDA clearance.
How Home A1c Tests Work
All home A1c tests require a small blood sample, usually collected by pricking your finger with an included lancet. What happens next depends on the type of kit you choose.
Mail-in kits have you place your blood drops on a collection card or into a small vial, then ship it to a certified lab. You typically get results online within a few business days. These kits measure the same thing a doctor’s lab order does: the percentage of your hemoglobin that has glucose attached, reflecting your average blood sugar over the past 8 to 12 weeks. Some kits, like the one offered by Labcorp, also report your estimated average glucose (eAG), which translates that percentage into an everyday blood sugar number in mg/dL.
Instant-result kits use a small analyzer device or test cartridge to process the sample at home, giving you a reading in roughly five minutes. These are less common and can be harder to find at retail, but they offer the convenience of immediate results without waiting for a lab.
What the Results Mean
Your result will come back as a percentage. The standard thresholds are straightforward:
- Below 5.7%: Normal range
- 5.7% to 6.4%: Prediabetes range
- 6.5% or higher: Diabetes range
If you already have diabetes and are managing it, your target is usually below 7%, though your doctor may set a different goal based on your situation. Many kits also report your eAG, which converts the percentage into the kind of blood sugar number you’d see on a glucose meter. For reference, an A1c of 7% corresponds to an average blood sugar of about 154 mg/dL, while an A1c of 8% corresponds to roughly 183 mg/dL. That conversion makes it easier to connect your A1c to the daily readings you may already be tracking.
Cost and Where to Buy
FDA-cleared home A1c kits generally cost between $50 and $100 per test. The DTI Laboratories A1c Test, one of the few with full FDA approval, runs about $52. The LetsGetChecked Diabetes and Heart Test, which bundles A1c with other markers, costs around $99. Both are mail-in kits ordered online.
Most home A1c kits are not covered by insurance, so you’ll pay out of pocket. If cost is a concern, it’s worth checking whether your insurance covers a standard lab A1c draw, which may end up cheaper with a copay. Many primary care offices can run the test during a routine visit at no additional appointment cost.
How Accurate Are Home Tests?
Mail-in kits processed by certified labs generally produce results comparable to what you’d get from a doctor’s office blood draw. The lab equipment is the same; the main variable is how well you collect and handle your sample. Following the instructions carefully, especially filling the collection card with enough blood and mailing it promptly, matters for accuracy.
That said, certain health conditions can throw off any A1c result, whether it’s done at home or in a clinic. The CDC lists several factors that can falsely raise or lower your number:
- Blood disorders: Sickle cell anemia and thalassemia alter hemoglobin structure, which directly interferes with the measurement.
- Severe anemia: Changes in red blood cell turnover skew the result.
- Kidney failure or liver disease: Both can affect how long red blood cells survive, shifting the A1c reading.
- Recent blood loss or transfusions: These replace your red blood cells with ones that haven’t had time to accumulate glucose.
- Certain medications: Opioids and some HIV medications can alter results.
- Pregnancy: Both early and late pregnancy can cause inaccurate readings.
If any of these apply to you, a home A1c test may give you a misleading number. In those cases, your doctor will likely use a different method to assess blood sugar control.
How Often to Test
The American Diabetes Association recommends A1c testing at least twice a year for people with diabetes who are meeting their treatment goals. If you’re adjusting medications, changing your diet significantly, or not hitting your targets, more frequent testing makes sense, potentially every three months. Testing more often than every three months rarely adds useful information, because A1c reflects an 8- to 12-week average and needs time to shift.
For people without a diabetes diagnosis who are curious about their blood sugar trends, a single home test can be a reasonable screening step. An A1c in the prediabetes range (5.7% to 6.4%) is worth following up on with a healthcare provider, who can confirm the result and discuss next steps. A result in the diabetes range (6.5% or above) on a home test should always be confirmed with a clinical lab test before any diagnosis is made.
Home Tests vs. Lab Tests
The main advantage of a home test is convenience. You skip the appointment, the waiting room, and the blood draw from a vein. For people who are already managing diabetes and want to check their progress between visits, a home kit can fill the gap without disrupting their schedule.
The main tradeoff is context. When your doctor orders an A1c, it’s usually part of a broader panel that might include fasting glucose, kidney function markers, or cholesterol. A home A1c test gives you one number in isolation. That number is useful, but it doesn’t replace the fuller picture a clinical visit provides, especially if you’re making treatment decisions based on the result.
