Proteinuria
Last week, we talked about haematuria, which is the presence of blood in the urine.
Today, we will discuss proteinuria, which can also be reported during routine urinalysis.
A small amount of protein in the urine is excreted in normal individuals more in the erect position than when lying down.
The amount of urine excreted and considered in normal value is 150 mg per day.
There are two types of proteinuria: the nonpathologic and the pathologic proteinuria.
Nonpathologic proteinuria can be: 1) Febrile proteinuria = presence of 1+ or 2+ proteinuria in high fever, or 2) Functional Proteinuria = exercise, cold and emotions may result in a transiently increased rate of protein excretion and this is related to renal vasoconstriction
Pathologic proteinuria are seen in glomerular and other renal diseases like: 1) Nephrotic syndrome2) Acute and focal glomerulonephritis3) Chronic glomerulonephritis 4) Hemolytic- uremic syndrome5) Asymptomatic Persistent Proteinuria – this is not common in children below 10 years of age, 6. Orthostatic Proteinuria- this condition is also not common among healthy children
