Urinalysis / Kidney
Also known as: WBC esterase test, LE test
Seek urgent medical care if you have a fever, chills, severe back or side pain, nausea, vomiting, or are unable to keep fluids down, as these could be signs of a more serious infection.
This test checks your pee for a special enzyme. This enzyme is called leukocyte esterase. White blood cells make this enzyme. White blood cells help your body fight off sickness.
Your doctor orders this test to look for signs of infection or swelling in your urinary system. This is especially true if you have symptoms like peeing that hurts or needing to go often.
Reference ranges for leukocyte esterase can vary between different laboratories. Your doctor will interpret your results based on the lab's specific ranges and your overall health.
