Red blood cells are thus much more common than the other blood particles: there are about 4,000â11,000 white blood cells and about 150,000â400,000 platelets in each microliter of human blood. Human red blood cells take on average 20 seconds to complete one cycle of circulation.
Â­Â­Your kidneys receive the blood from the renal artery, process it, return the processed blood to the body through the renal vein andÂ­ remove the wastes and other unwanted substances in the urine. Urine flows from the kidneys through the ureters to the bladder. In the bladder, the urine is stored until it is excreted from the body through the urethra. Now let's take a look inside your kidneys.
Urinalysis, also called a routine urine test, is used to check for abnormalities in the urine.Urine is liquid waste, which is made by the kidneys and stored in the bladder until it is eliminated by the body through urination.rinalysis should be performed within 15 minutes of collecting the urine sample. If that is not possible, the urine should be refrigerated. Some parts of routine urinalysis are performed using a dipstick test or tablet test, and others are completed using microscopic (under a microscope) evaluation in a laboratory.
