How long is the shelf life of Roche blood glucose meter test paper? The test paper I left behind for a while can't be used.

Roche's test paper shelf life is generally half a year. It is best to have a comprehensive test paper. Each one is sealed. Don't worry about oxidation. You can go to the health boat to find out. The expiration date on the package. You can use it before this expiration date. Roche test paper did not say that it could not be used for 3 months after opening. Available months. Or buy an individually packaged blood glucose meter (Abbott). I suggest you buy it in a store with a physical store. Ensure quality. The guarantee period is long. Ensure authenticity. buy by mail order
