Healthy Kidneys prevent Blood & Protein in Urine. But how?!

Protein blood barrier

Normally, Urine produced by healthy kidneys is a cocktail of toxic waste products of cellular metabolism, a host of minerals, salts, smelly organic compounds & excess water. (Find the complete normal urine composition here). These components begin to get together to form Urine once healthy kidney micro-filters “strain” our blood through themselves. These micro-filters are uber-selective with what they “let-out” into the urine. This is such that, all blood cells & “plasma” proteins remain in the bloodstream while the wastes & excesses purge themselves out.

But what makes these Kidney Micro-filters that selective against leakage of blood cells & protein in urine?

Haematuria

WHAT IS HAEMATURIA?

Haematuria is the technical term for the presence of red blood cells (RBCs) in urine. This could range from minute quantities such that it is invisible to the naked eye (occult or hidden bleeding), to frank hematuria such that the urine assumes a reddish tinge to a cola-coloured appearance.

Red blood cells abundantly present in our bloodstream happen to carry a pigment called “Haemoglobin” within them. This is what gives our blood, a red colour and lends that reddish tinge to most urine samples that have blood in it.

Please note: For Haematuria, the urine sample must contain whole red blood cells and not just the red pigment of blood.
