Pros and Cons of At-Home A1C Testing for Type 2 Diabetes

Pros of At-Home A1C Testing
Fast Results
“Some tests provide results right away,” says Ruchi Mathur, MD, an endocrinologist and the director of Cedars-Sinai’s Diabetes Outpatient Treatment and Outpatient Education Center in Los Angeles and the director of clinical research and clinical operations for the Medically Associated Science and Technology program.
Accessible Testing
“The advantages of using the at-home A1C testing are especially helpful for patients who do not have easy access to a lab or physician’s office where they can have their blood drawn,” says Barbara Keber, MD, a primary care physician, the vice chair of family medicine at Northwell Health in Glen Cove, New York, and a professor in the department of family medicine at Hofstra University’s Zucker School of Medicine.
Ease of Use
Treatment Adjustments
“Having a recent A1C result can help patients and healthcare professionals decide whether diabetes treatment may need to be adjusted, including during telehealth visits,” says Mathur.
New Perspective
Cons of At-Home A1C Testing
Lower Accuracy
Danger of Incorrect Medication Dosage
Not for Diagnosis
Is At-Home A1C Testing Right for You?
Ability to Take the Test and Read the Results
Proper technique may be difficult if you have health issues like arthritis, a prior stroke, or another reason that you’re not able to collect the blood sample properly. “If the samples are not obtained correctly, it will lead to inaccurate results and potentially an incorrect change in a person’s medication, based on a [wrong] result,” says Keber.
You will also need to learn what your results mean, and what action, if any, should be taken. “If a home result is unexpected or could lead to a major change in treatment, your healthcare professional may recommend confirming it with a laboratory A1C test,” says Mathur.
Test Cost
Stress With Testing or Results
Quality issues with home testing can lead to unnecessary stress or a false sense of security. “While not all tests are inaccurate, they are simply not as reliable as a ‘gold standard’ lab draw, and in the worst case scenario, if medication changes are made [based] on inaccurate data, it can be a significant health issue,” says Mathur.
