Hi,
Your son needs further evaluation.Trace urine in the blood or microscopic hematuria needs to be assessed.In children, a glomerular ( disease of small kidney units) disease has to be ruled out. Was his blood pressure determined? A 24 hour urine sample collection to check for the presence of protein and casts may be able to help.
If your son is currently lethargic and irritable, I suggest that you bring him to the ER. Blood tests may be needed to rule out the presence of infections .
Thanks for your response. The dr. ordered an ultrasound of his kidneys and a CBC. His Metabolic profile came back normal. The ultrasound showed an enlarged spleen. Still waiting on results from the CBC. Anything else would should do, or does it sound like a case of mono. The Dr. also ordered that test as well (we are still waiting). Would having the mono cause the hematuria? Thanks for your help. Faith
