I'm so confused by the results, I want to get tested a third time. We first tested at the clinic, and the result was surprising – likely due to improper sample collection. Yesterday, I tested at Invitro, and the result was normal, but I was concerned about the leukocyte esterase indicator, which wasn't present in the clinic's results. However, the leukocytes themselves are within the normal range, as is everything else. I'm not sure if I should go for a third test somewhere else. My appointment with the pediatrician for tomorrow was canceled, and we can't be re-registered until they sort it out. While we wait for the lab referral, a lot of time could be lost if there really is something wrong – God forbid.
