Leukocyte esterase in the diagnosis of shoulder periprosthetic joint infection
Journal of Shoulder and Elbow Surgery, 2015Shoulder periprosthetic joint infection (PJI) is difficult to diagnose with traditional methods. Leukocyte esterase (LE) has recently proven to be reliable in knee arthroplasty; however, its value in the shoulder has not been explored. We hypothesized that LE would display high sensitivity and specificity in shoulder PJI.Two groups were prospectively ...

In vitro properties of diffuse cytoplasmic esterase-positive canine mononuclear leukocytes
Veterinary Immunology and Immunopathology, 1983Depletion of cytoplasmic esterase-positive canine peripheral blood monocytes from mononuclear cell suspensions was attempted using plastic adherence, carbonyl iron ingestion and/or Sephadex G-10 filtration. An esterase-positive, nonadherent, nonphagocytic subpopulation was identified and further characterized by the presence or absence of cell membrane

Applicability of leukocyte esterase test strip in detection of canine pyuria
Journal of the American Veterinary Medical Association, 1986SUMMARY A commercially available leukocyte esterase assay was evaluated for application in analyzing canine urine for the detection of pyuria. In 229 urine samples, the leukocyte esterase activity was compared with leukocyte concentrations, as assessed by microscopic sediment analysis and chamber cell counts.

ChemBioChem, 2018
We introduce a new class of substrates (compounds I–III) for leukocyte esterase (LE) that react with LE yielding anodic current in direct proportion to LE activity.

Leukocyte Esterase Activity in Effusion Fluid of Patients with Otitis Media
Otolaryngology–Head and Neck Surgery, 1993Fluid obtained during myringotomy and tube placement in 20 patients with middle ear effusions was assayed for leukocyte esterase activity using a quantitative spectrophotometric assay. This quantitative assay used the synthetic substrate, N‐tosyl indoxyl alaninate. Seven of the 20 samples showed no measurable enzyme activity (8 U/ml or less).

Rapid Diagnosis of Infected Ascitic Fluid Using Leukocyte Esterase Dipstick Testing
American Journal of Gastroenterology, 2004Ascitic fluid infection is presumptively diagnosed when the fluid polymorphonuclear leukocyte (PMN) concentration equals or exceeds 250 cells/microl. The leukocyte esterase (LE) test has been shown to be a good predictor of the presence of PMNs and bacteria in urine and other body fluids. This study examines the value of the Multistix 10 SG LE Dipstick

Detection of Bacteriuria by Leukocyte Esterase, Nitrite, and the Automicrobic System
American Journal of Clinical Pathology, 1984The predictive value for detection of significant bacteriuria was determined for use of the Chemstrip leukocyte esterase-nitrite dipstick (LN) and the Vitek Automicrobic System (AMS) using a conventional culture method (CM) as the reference procedure. The predictive values for positive and negative tests for detection of greater than or equal to 10(5 ...
