The expiration date of One Drop test strips depends on how they’re stored.
If the test strip container is opened, test strips expire 180 days after opening or by the expiration date printed on the label, whichever is sooner.
If the test strip container is closed, test strips expire by the expiration date printed on the label.
If you’ve received expired test strips, please contact us within 30 days of receiving them, so we can send you a replacement order.
Test strip containers must be stored within the conditions printed on the label to ensure accurate results. We cannot guarantee the accuracy of expired or improperly stored test strips.
