What does a positive result for leukocyte esterase ua from a urinalysis mean? You may have an infection. A positive finding of the enzyme leukocyte esterase in urinalysis indicates the presence of white blood cells in the urine. This normally suggests inflammation of some sort, often from a urinary tract infection. A simple dipstick test as part of a urinalysis can detect the presence of this enzyme.

Urinalysis 1 Leukocyte Esterase: Leukocyte esterase is an enzyme present in your white blood cells. 2  Therefore, the presence of this substance in the urine indicates the presence of white blood cells (leukocyturia).3  White blood cells in the urine may indicate inflammation of the kidneys or urinary tract due to bacterial infection.

Immunohistochemical Expression of Endothelial Markers CD31, CD34, von Willebrand Factor, and Fli-1 in Normal Human Tissues High endothelial venules were positive for CD31, CD34, and vWF. In the lymph node capsule, a reticular pattern of staining was also seen with CD34, probably corresponding to CD34-positive mesenchymal cells. Sinus histiocytes were positive for CD31 but negative for CD34 and vWF.D31, a member of the immunoglobulin superfamily, is a 130-kDa transmembrane glycoprotein also designated as PECAM-1 (platelet endothelial cell adhesion molecule 1). It is present on the surface of platelets, monocytes, macrophages, and neutrophils and is a constituent of the endothelial intercellular junction.

Leukocyte esterase A urine sample that tests positive for both nitrite and leukocyte esterase should be cultured for pathogenic bacteria. It has been proposed that the reagent strip for leukocyte esterase designed for the testing of urine (Combur test UX) could be a useful tool for diagnosing spontaneous bacterial peritonitis SBP.

- Human leukocyte antigen (HLA) typing is used to match you with a donor for your bone marrow or cord blood transplant. This is not the same as ABO blood typing. HLA is a protein – or marker – found on most cells in your body.

Leukocytes in Urine: Symptoms, Causes & Treatments Leukocytes in urine are not a dangerous condition, but they are a sign that you are suffering from an infection or damage. Leukocytes are white blood cells (WBC) that work with the immune system to defend against infectious disease. Damage to the kidneys, ureters, urethra or bladder can cause leukocytes to appear. strip test can be used to check the leukocyte levels in the urine. Your doctor can prescribe a microscopic test to manually check the leukocyte levels. They can also perform a strip test which will note abnormalities in the leukocytes.

- Positive results of LE and NT are often used as a reflex to a urine culture (both in the presence and absence of clinical symptoms of UTI) or, in some cases, even to initiate empiric treatment while the culture results are pending.

- Tests to detect nitrites and leukocyte esterase have become part of a routine urinalysis. Most species of bacteria that colonize in the urine cause nitrates, which are derived from dietary metabolites, to be converted to nitrites. In healthy people, both the urinary nitrite test and the leukocyte esterase (LE) tests are negative. A negative nitrite test does not necessarily mean that the urine is free of all bacteria, particularly if there are clinical symptoms, because some bacteria do not produce nitrites.

Leukocyte esterase in urine 1 When the urinary system is blocked it could result in blood in urine. 2  The urinary system could be blocked due to kidney or bladder stones, trauma, hypertrophy or pelvis tumor or unnecessary foreign particles in the urinary tract. 3  Infection in kidney could also raise the level of leukocytes esterase in urine.idneys, bladder, ureters and urethra form the urinary system and when analysis of urine shows leukocytes (without nitrates) in urine it indicates infection in the system. To diagnose leukocytes, urinalysis has to be done in order to know the level of leukocytes esterase in urine.

Urinary Tract Infection: Providing the Best Care Leukocyte esterase, nitrates, protein, and blood are the important features in evaluating for UTI. The presence of leukocyte esterase on a urine dipstick is equivalent to ≥ 4 white blood cells per high-power field (WBC/hpf). Nearly all (≥ 96%) patients with UTI have pyuria equivalent to > 10 WBC/hpf.

- Leukocyte esterase. When testing for urinary tract infections, the sensitivity of the urine dipstick test for leukocyte esterase has been found to be, in general, slightly higher than for the dipstick test for nitrites (48-86%), while the specificity was slightly lower (17-93%). Ketones are not normally found in urine. 2  Dipstick tests for the presence of acetoacetic acid at 5-10 mg/dL but not acetone or beta-hydroxybutyric acid. 3  A positive test is associated with uncontrolled diabetes, pregnancy without diabetes, carbohydrate-free diets and starvation.

Human leukocyte antigen test Definition. The human leukocyte antigen (HLA) test, also known as HLA typing or tissue typing, identifies antigens on the white blood cells (WBCs) that determine tissue compatibility for organ transplantation (that is, histocompatibility testing).uman leukocyte antigen testing is performed to reduce the probability of both rejection and GVHD. Typing is also used along with blood typing and DNA tests to determine the parentage (that is, for paternity testing).

HLA protein is made up of six antigens, molecules that stimulate an immune response and help your body identify which cells belong to your body and which do not.t is the responsibility of a transplant center to find a stem cell donor for a patient, and not the individual. A doctor may perform a preliminary search for a donor without obliging the patient to necessarily undergo a stem cell transplant.
