Just received the four boxes of two each iHealth kits. Half were dated 8/16/2022 and half 8/19/2022. But I checked the lot numbers on the iHealth web site and both expiration dates have been extended three more months, so expirations in November 2022. The same happened with my earlier government iHealth kits.
The four FlowFlex tests that my husband got last week at CVS covered by Medicare have expirations of 11/16/2022. The eight BinexNow tests that I got a few weeks ago at Walgreens covered by Medicare have expirations of 6/4/2023. Based on that info, I suspect the other companies will continue to extend expiration dates - they likely just got their product testing started later.
