Why do diabetes test strips expire?
Diabetes test strips expire because they lose accuracy over time due to factors such as oxygen, humidity and aging; even diabetes test strips sealed in an airtight package can give an inaccurate reading. Typically, blood sugar testing strips are considering ‘expired’ three months after they are opened. Although control solution may be able to help you determine if your test strips are still viable, it is best to abide by the diabetes test strip’s expiration date given to avoid any potential misreadings.
