The main difference between filtrate and urine is the chemical composition of the two. Filtrate has almost all the substance that blood plasma has except blood proteins while urine only contains waste substances.

Ions and nutrients
The two things that might indicate problems in health would be proteins and glucose. Proteins in filtrate or urine would indicate a possible kidney infection and glucose would indicate possible diabetes.
The two main substances found in urine are water and waste products, such as urea, creatinine, and uric acid.
Basically blood plasma minus proteins. The glomeruli can filter out most serum proteins, but lets a few small ones through (I think the cutoff is like 25kD). Some albumin does manage to get through, this is recovered in the proximal tubule.
The two stages of filtration in the nephrons are glomerular filtration and tubular reabsorption. Glomerular filtration occurs in the glomerulus where blood is filtered to form a filtrate. Tubular reabsorption involves the reabsorption of essential substances such as water, glucose, and ions back into the bloodstream from the filtrate in the renal tubules.
Protein and water
Plasma proteins and red blood cells are not excreted in urine because they remain in the blood when it is filtered through the kidneys and into the ureters. They are too big to be filtered. Most other substances present in blood are also present in urine since the kidneys filter out poisonous substances as well as substances that are present in excess such as salt and water.
Mostly urine performing time less then two hours . If urine perform after two hour or more late then bacteria growth in the urine and urine container. when this urine perform time nitrites positive because late perform urine bacteria growth. But not found of leukocyte in microscopically in this urine . this urine repeated and perform under timing then not positive nitrites and not found in leukocyte in urine. Airf Hussain (M.Sc.
