One can find a high number of leukocytes (white blood cells) in the urine sample, is usually a bacterial infection of the kidneys and / or urinary tract blame. But other inflammatory conditions can increase the leukocyte count in the urine.
Leukocytes are body's defenses. They have different responsibilities and capabilities. Leukocytes are for example able to detect exogenous structures and destroy - this includes "intruders" such as bacteria or viruses. If an infection or inflammation of the body produces more white blood cells and transports them to the blood to the required locations.
Leukocytes are constantly challenged and only survive for a limited time. Dead or damaged leukocytes separates from the body via the kidneys and eventually the urine. This happens constantly - a small amount of white blood cells in the urine is therefore normal.
With the common causes for elevated levels include bacterial infections
also known as sterile inflammation - So inflammations in which Although leukocytes, but no bacteria in the urine can be detected (. so-called sterile leucocyturia) - may increase in urine, such as the number of white blood cells:
A urine sample is information on whether the leukocyte count is increased. To determine if too many white blood cells are present, use practices usually special test strips, the dipping into the urine. discolor the strip, which indicates an increased number.
But an examination of the urine using the microscope is possible. Leukocytes are present, you can see this visually and counting. Microscopic examination often follows, when the test strip is responding positively to leukocytes. Depending on the result further investigation may be necessary.
