You’ll see a positive or negative result within one minute. 5,000 RLUs and above is a positive UTI result. Below 5,000 RLUs is a negative UTI result. You should follow a result of 5,000-20,000 RLUs by repeating Test 1 with a longer incubation time e.g 60 minutes. When you’ve confirmed a positive result, move onto Test 2.
