Yes a couple of times I’ve had traces of protein and leukocytes so they ask me to do another sample and send it off to a lab to make sure I don’t have an infection or anything. Results have always come back fine
Sometimes it’s due to a trace of protein in your urine. Had you eaten or drank anything quite sweet prior to the appointment ? X
I had that a couple times and it was because there was too much protein in my sample, try not to stress too much as usually easy fixes xx
