Blood in 3 Year Old

[Meagain24]

For background father has a genetic kidney disease which typically starts later in life & usually causes heavy protein loss. Child has not been tested for the gene

3 year old had a urine test less than 48 hours after he was sick from a sickness bug. This showed 33 red blood cells and 1+ protein. 1 week later it showed 11 red bloods and no protein, another 2 weeks later (3 weeks after the sickness) it showed 7rbc and no protein again.

I guess a couple of qs

if anyone has any experience of kidney issues in children - would it be unusual for there to just be blood and no protein?

Has anyone’s child ever had blood in urine after a bug that took weeks to clear?

any input at all would be amazing. Thank you.

Really think you need to talk to a specialist

The most reassuring thing about these results is that the red blood cell count is steadily falling, and the protein has disappeared. ❤️
Here's how I'd interpret the results for this 3-year-old:
Can children have blood in their urine without protein?
Yes, absolutely. Microscopic haematuria (blood cells detected on urine testing but not necessarily visible) can occur without protein.
In children, this can happen temporarily following an illness. The absence of persistent protein is generally reassuring, although it doesn't completely exclude an underlying condition.
Can it take weeks to disappear?
Yes. Microscopic blood in urine can persist for several weeks after an infection, even when the child otherwise seems completely well.
The downward trend from 33 to 11 to 7 is encouraging, particularly alongside the disappearance of protein.
What about the father's genetic condition?
This is the one detail that makes follow-up particularly important.
Some inherited conditions can initially cause microscopic blood without protein, while others typically cause protein loss.
Because the child has had three positive urine tests and a family history, I'd recommend discussing the results with a paediatrician, including whether genetic counselling or testing is appropriate. A blood pressure check and a urine protein-to-creatinine ratio may also be useful.
My overall impression: The improvement is genuinely encouraging, and a temporary post-illness change is a plausible explanation. But the results alone cannot establish the cause

@Washingforweeks thank you!

he had a UPCR each time - first time during bug it was abnormal, following two times it was normal and also had his blood pressure checked which was normal too. it just seems to be this blood which is lingering - the dr said 5 & under is normal and his was 7 this time.
