Leukocyte esterase is an enzyme that is released by white blood cells (WBCs) and therefore correlates with pyuria. Some bacteria (such as E. coli) convert urinary nitrates that are routinely present in the urine into nitrite. Therefore, a positive nitrite test on the urine dipstick is ...

Hematuria is the presence of occult blood in urine due to glomerular damage, tumors, kidney trauma, urinary stones, acute tubular necrosis, UTI, and nephrotoxins. Dipsticks to detect occult blood are sensitive to any heme group and may suggest the presence of either intact RBCs, hemoglobin...

Although both the dipstick and the sulfosalicylic testing methods estimate the concentration of protein in the urine, small amounts of protein in very concentrated urine will show up as more positive than the same amount of protein present in dilute urine. A number of studies have demonstrated ...
A dipstick test is usually performed on the urine specimen to check for: glucose (sugar) in the urine, ketone in the urine (metabolic waste product), blood in the urine (detected ashemoglobinin the urine), leukocyte esterase (suggests white blood cell in the urine), ...
