*Red blood cell. It is also a sign of damaged kidneys when there are increased amount of reb blood cells in your urine and almost of them are deformed
*β2-microglobulin. When glomerular filtration rate and renal tubular reabsorption function decrease, β2-microglobulin can come into the urine.
*NAG. There is more NAG in urine for Hypertensive Nephropathy patients.
-Blood test. Blood tests is also required to determine how well the kidneys are functioning. When there is slight damage to kidney, β2-microglobulin in the blood will increase. So β2-microglobulin can be an indicator of kidney function.
