Can I use expired test strips?

10 posts in this topic

Hi, How long can I use expired test strips or should I get new ones?

 

Thanks, Rob

 

Funny you should ask that question tonight! From all my years of testing, using MANY different meters, I'd say that 2 months past expiration is PROBABLY ok, but I'd do a comparison on the strips with unexpired ones.

 

Tonight I grabbed an old meter (SureStep) with strips from 2002. The reading should have been 160, but was 120, a noticeable error. I'd NEVER intentionally use strips more than a few months old.

 

some strips technology seems to be more error prone shortly after going out of date, so there's no hard and fast rule. Technically, you aren't "supposed" to use outdated strips (my little disclaimer). I've got so many meters, that I can cross check results to my hearts content. My "gold standard" is an UltraSmart. I use the Flash, UltraSmart, Ultra, Accucheck Compact and once in a blue moon, a BD Logic, which I hate.

 

Make sure to promptly cap the vial after retrieving a strip using a DRY finger. don't store them in the car during even modestly warm weather. absolutely don't store in the car during hot summers.

My meter is a FreeStyle and test strips did expire in 03/2005 and I hate to get rid of them because I have 3 bottles.

Surely you have calibration fluids that you can check them with!?

I recently went through all my strips and have been using them in order of about-to-expire so I don't have expired strips on hand any more. I have used strips that were about two months expired, and the results were within normal as far as I can tell. I compared a couple times with strips that were okay and the variance was negligible. However, if I ever get a HIGH or real low reading with the Freestyle-expired strips, I will re-test with good strips.

 

Like Peter said, use the calibrating solution if in doubt.

I used an Accu-Chek strip that had expired over a year before and it was 2 mg/dL lower than the lab results. An unexpired Ultra strip was about 20 mg/dL higher than the lab results.

I hope everyone who read my previous post realized I MEANT I'd never intentionally use strips that are more than a few months out of expiration. If I was desperate, I might, but I'm never desperate for strips.

Could always call the company and ssee what they think.

Or sell them on ebay if you can't use them all or on here to some people.

Only if you've given them a proper burial.

 

But then why would you want something that was entombed?

 

 

Geez, I've never had any strips that were close to being expired.

I've never had test strips sit around long enough for the to expire, but I would say to not use them if they are more than a month. And, even then, test with the control solution to make sure. You might as well get rid of them if they are not going to give you an accurate reading anyway, you know? Also, try maybe calling customer service for your brand. I've heard of some who will send you replacement strips if you are within a certain amount of time after the expiration. It is worth looking into :)
