Diabetes, or diabetes mellitus, is a common and chronic health condition that affects how the body uses glucose. According to the Centers for Disease Control and Prevention (CDC), it affects over 34 million people living in the United States. Diabetes can increase your risk of heart problems, stroke, and nerve damage.

A further 88 million people have prediabetes, which typically occurs before diabetes. In prediabetes, blood sugar levels are elevated, but not to the levels of diabetes.

Many people are unaware they have prediabetes or diabetes until they experience health problems. Understanding the warning signs and regularly testing are ways of safeguarding your health from the severe health complications of diabetes.

It’s worth knowing that you can now buy at-home diabetes testing kits to monitor your blood glucose with A1C testing. Depending on your results, you can then consult a doctor.

If you’re looking for an easy way to test for diabetes at home, here are our top choices.

If you’re concerned that you’re at risk for diabetes, here are some of the most common causes and symptoms.

Type 1 diabetes

Doctors don’t currently know the primary cause of type 1 diabetes. In some cases, genetics may play a role. Symptoms can include:

  • extreme hunger
  • increased thirst
  • unintentional weight loss
  • frequent urination
  • blurry vision
  • tiredness

Type 2 diabetes

Type 2 diabetes typically stems from a combination of genetics and lifestyle factors. Being overweight or having obesity can heighten your risk. Additionally, family members may share genes that make them more likely to get type 2 diabetes and to be overweight.

Symptoms may include:

  • increased hunger
  • increased thirst
  • increased urination
  • blurry vision
  • tiredness
  • sores that are slow to heal

There are also gender-specific symptoms for type 1 and type 2 diabetes. For men, symptoms may include:

  • a decreased sex drive
  • erectile dysfunction
  • poor muscle strength

Women may experience:

  • urinary tract infections
  • yeast infections
  • dry, itchy skin

Home diabetes tests usually provide everything you need to test A1C, also called HbA1c. According to the American Diabetes Association, this metric shows your average blood glucose levels over the previous 2 to 3 months, rather than standard glucose testing that only provides a snapshot of that moment.

Because A1C tests provide an overall picture of your blood sugar levels, they’re a good indicator of how your body manages glucose.

At-home diabetes tests allow you to take a blood sample at home and mail it to a laboratory for analysis. Then, after a few days, you’ll receive your results through a phone app, email, or on a secure web platform.

If there are any atypical results, follow up with your primary care physician to discuss the next steps.

Anyone who wants to understand their risk of diabetes should take an at-home diabetes test. Because these kits only require blood from a finger prick, they’re safe for most people to use. You can then use the results to see if you need medical guidance.

That said, people living with diabetes should seek their doctor’s advice if they are considering using these tests to replace their routine monitoring or specially ordered tests.

Your results indicate your levels of glycated hemoglobin or HbA1c. When blood glucose binds with the hemoglobin in red blood cells, it forms A1C and is detectable in the blood for 2 to 3 months.

A1C levels increase in line with blood glucose, meaning high blood glucose equals high A1C.

According to the American Diabetes Association:

  • HbA1c levels under 5.7 percent are “normal.”
  • 5.7 percent to 6.5 percent means prediabetes.
  • 6.5 percent or higher indicates diabetes.

What is the HbA1c level?

The HbA1c level indicates your average blood sugar levels over the past 2 to 3 months.

The HbA1c or A1C test measures the amount of blood sugar or glucose that’s bound to your red blood cells. If your body can’t use glucose as it should, more of it sticks to the blood cells and builds up.

Doctors use the test results to diagnose and monitor prediabetes and diabetes. The results are reported as a percentage, and typical levels are less than 5.7 percent.

What kind of samples are required for an at-home diabetes test?

Most at-home diabetes tests require a finger-prick blood sample. It involves using a tiny scalpel called a lancet to prick the side of your finger. You’ll then collect the drop of blood on the test strip or sample collection board.

If you opt for a diabetes panel, you may also need to provide a urine sample.

What does an at-home diabetes test kit include?

Most of the tests we’ve reviewed come with instructions, a lancet to prick your finger, and a sample collection device. In addition, there’s typically a prepaid shipping label or envelope and an ID number used for registration on the company website and for marking your specimen.

Does Medicare cover at-home diabetes tests?

No, Medicare and insurance companies usually don’t cover at-home diabetes tests. However, there may be exceptions. Always contact your insurance company to double-check.

At-home diabetes tests are an affordable and efficient way of screening for diabetes. Using these tests can help you monitor how your body uses glucose and assess your risk of diabetes, especially if it’s common in your family.
