What is leukocytes esterase?
leukocytes esterase (LE) is a type of urine test that is most often used to diagnose urinary tract infection (UTI). The test is also known as WBS Estheras. It is used to determine whether white blood cells are in the urine, which indicates infection. More specifically, it seeks to release the enzyme of white blood cells called esterase. The LE test is often used with urinary nitrite test to confirm the UTI.
le test is painless, fast and non -invasive. In order to test the leukocyte esterase, the patient must provide a pure urine sample. Then the doctor inserts a belt known as a gauge into the urine. The measurement has several different color blocks, each of which will or does not change color depending on the urine content. One of them is formulated to change color if there are elements that indicate leukocytes in the urine. There are several things that can cause the test to have falsely negative, such as a large amount of vitamin C or protein in the urine. It is also possible to get falsely positive due to infection or secretion of tricHomonas from vagina, such as mucus or blood.
Positive leukocyte esterase usually suggests an infection, although it could also be some other kind of contamination. If the patient has other signs of UTI, treatment is often initiated for this condition without further testing. In cases where the patient does not have symptoms of infection, urine culture or sample examination under a microscope may be required to diagnose.
The results of leukocyte esterase and the presence of combined symptoms can help doctors diagnose urinary tract infection. These symptoms include a constant, urgent need to urinate, Tygh produced are a small and burning feeling of urination. Urine may also look cloudy or have a pink shade due to the presence of blood. Urine can also have a strong smell. Urine infection can affect the urethra, bladder or kidneys.
urinary tract infections are usually treated with oral antibiotIky. If the infection is serious, hospitalization and intravenous (IV) administration of antibiotics may be required. Hospitalization is usually the result of infection in the kidneys.
