Hi Louli,
Welcome to HCM
First of all I would like to inform you that it is a very important question specially in 2 month old baby.When routine urine examination shows very large number of
pus cell along with high number of red blood
cells then it is a cause of serious concern.
There are two primary possibility 1.
Urinary tract infection and 2.Glomerulonephritis(type of kidney disease).Both of them needs prompt treatment as this age group it is not common.
So please go to nearest
pediatric hospital or pediatric clinic as soon as possible.
Thanking you.
