,,, not sure if allowed to mention the brand here, but went to get some more today on Amazon.ca and they no longer have the ones I use - can get on EBay but I am a creature of habit, so today ordered a different brand. I am on antibiotic right now for uti - symptoms and test strip showed leukocytes and blood ... hated to go to emerge yeserda as they are short staffed - now in Ontario Canada our pharmacists can dispense antibiotics for uit’s. But when I phoned with symptoms he said not an uncomplicated one so go to emerge! Not sure how they diagnose as was told they dont use the test strips now??? Anyway, sample has been sent for a culture which takes five days... had a rough night last night first time ever with one, unable to hold urine in and had a mess to clean up this morning - so maybe there is more gong on... elderly now so everything is falling apart! I have used the test strips for years and although could have false negative or positive, gives a clue to what is going on, IMO. 2nd day on pills and still showing microscopic blood so will see how it goes tomorrow.
