Lactate strips - storage and expiry date

Triathlon Forum
1

Hi ST,

Are expired lactate test strips still providing relevant results (and if so for how long - I have some expired in April 2020) or is the expiry date a real thing?

And how important is it to store them in the fridge (not a problem at home of course, but some strips I bought took two weeks to get to my place and were therefore not stored in the cold during this period).

Thanks

Do you have the control solutions?
If they test in-range I’d use them for non-diagnostic work.
