Why the Test is Performed. Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine. This may mean you have a urinary tract infection. If this test is positive, the urine should be examined under a microscope for white blood cells and other signs that point to an infection.
Pus cells are a collection of dead, white blood cells that accumulates when the body’s immune system activates in response to an infection. These cells form a whitish-yellow or yellowish colored protein rich fluid at the site of the infection. This fluid is known as liquor puris. These pus cells may sometimes be present in your urine.
The sensitivity and specificity of BTA to detect BCa was 72% and 53%, respectively. Hematuria, measured by urinary hemoglobin, was a better indicator of BCa with 75% sensitivity and 90% specificity. Spiking of BTA-negative urine samples with as little as 1μl/10ml was enough to produce positive a BTA test. High levels of BTA were found equally
The sensitivity for Multistix reagent strips is 5 cells per high power field (hpf) to 15 cells/hpf while Chemstrip reagent strips have a sensitivity of 20 leukocytes per uL of urine. Because of this relative insensitivity, the absence of leukocyte esterase does not rule out urinary tract infection (UTI).
Dec 22, 2020 · Dr. Evan Altman answered. Psychiatry 21 years experience. Leukocytes = WBCs: White blood cells in the urine indicate that an inflammatory or immune system reaction is taking place. Nitrates can be normal in urine. Nitrites can indicate infection. Without more information, in terms of other urine or laboratory markers, symptoms, etc.
