Blood In Urine

My fifteen year old son about 3 months ago had blood in his urine.  It past and then a few days ago, he had blood in his urine again, this time the color of a ripe tomato.  Took him to the doctor, they did blood test, which won't be back until Monday, and ordered a CT urocan.  But they said he wouldn't be able to do the uroscan if something came back in the bloodwork.  What would show up in the blood work?  He has no pain urinating and no low or high back pain, just the blood in the urine.

He's not having any nausea, vomiting, abd. pain, fever, chills or lightheadedness.  Just blood in the urine.

I feel for you.  My son is also 15 and has the exact same thing.  He has had blood for the past 3 weeks, almost one month.  They did 2 urinalysis, blood work, and an ultrasound all to come back negative.  He still has blood off and on but now there is slight burning when he starts to urinate. We have an appointment with a Urologist at the end of this month.  It is so frustrating. Please let me know what happens.
