How To Control High Amount Of Leukocytes In Urine?

hi, my 9yr daughter has extremly high amount of leukocytes showing up in her urine dip test, it was instant. she has no nitrate, protein or blood showing up at all. which she does normally if she has a reacurrant uti or kidney inf. she has also lost a lot of weight, has almost stopped eating completly. she is constantly tired and has no energy at all, this has been going on for a while in all. but just got a lot worse over the last 10days. the doctor suspected 6wk ago she was anaemic, but due to her autism we didnt manage to get a blood test. so we hav been trying to get iron supplement down her. she is still going downhill rapidly. she has an illiostomy aswell.
