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.
