Yes — diabetic test strips expire, and the expiration date matters a lot when you sell them. Buyers can only purchase sealed strips that are still well within date, because expired strips can give inaccurate readings and aren’t safe for someone else to use.
Why test strips have an expiration date
Test strips contain chemicals (enzymes) that react with a drop of blood to measure glucose. Over time those chemicals degrade, which can make readings less accurate. That’s why every box carries an expiration date — and why only unexpired strips should be used or sold.
Where to find the expiration date
Look for the printed expiration date on the end flap or side of the box, usually next to a small hourglass symbol or the letters “EXP.” Many boxes also show a lot number nearby, which manufacturers use for tracking.
How much shelf life do buyers want?
Most buyers, including Diabetic Dollars Direct, want strips with several months of life left — often six months or more. The further out the date, the more your box is worth. Strips that are expired, or very close to it, generally can’t be purchased.
Selling before they expire
If you have extra sealed boxes, the best time to sell is now, while the dates are far out. Waiting only lowers their value. Get a free quote to see what your in-date strips are worth.
