Leukocyte esterase: When WBCs in the urine undergo lysis, esterases are released. Therefore, a positive leukocyte esterase test generally implies the presence of underlying pyuria and urinary tract infection. Sterile pyuria is usually seen in analgesic nephropathy and in urinary tract infections caused...
Urine is generally thought of as a sterile body fluid, therefore, evidence of white blood cells or bacteria in the urine is considered abnormal and may suggest a urinary tract infection such as bladder infection (cystitis), or infection of the kidney (pyelonephritis). White blood cells (WBC) ...
A 30-year-old male patient has a positive leukocyte esterase and nitrites on a random urine dipstick during a well patient exam. What type of urinary tract infection does this represent? Which of the following may indicate liver disease? a. glycosuria b. ketonuria c. hemoglobinu...
Objectives: Urinalysis by automated urine analyzer, including microscopy and dipstick test, is easy, rapid, and inexpensive. Among these parameters, leukocyte count (WBC) or leukocyte esterase (LE) has relatively sufficient sensitivity in urinary tract infection (UTI) detection. U...
Leukocyte esterase test: A positive test is seen in the presence of WBCs in urine and suggestive of pyuria. URINE pH: The glomerular filtrate is usually acidified by renal tubules and collective ducts. The pH of urine normally ranges from 4.5 to 7.5. Urine pH should be measured with ...

The diazonium compound in turn couples with 1,2,3,4-tetrahydrobenzo(h) quinolin to produce a pink color. Leukocytes: This test is based on the action of esterase present in leukocytes, which catalyzes the hydrolysis of an indoxyl ester derivative. The indoxyl ester liberated reacts with a ...
