False-negative nitrite tests in urinary tract infections occur in cases with a low colony forming unit (CFU) count, or in recently voided or dilute urine. [4] In addition, a nitrite test does not detect organisms unable to reduce nitrate to nitrite, such as enterococci, staphylococci (Staphylococcus saprophyticus), Acinetobacter, or adenovirus. [4]
Clinicians will often treat symptomatic bacteriuria based on the results of the urine dipstick test while waiting for the culture results. [citation needed] Bacteriuria can usually be detected using a urine dipstick test. The nitrite test detects nitrate-reducing bacteria if growing in high numbers in urine. A negative dipstick test does not ...

Trace levels of protein in the urine can be normal, [60] but high levels (proteinuria) can indicate kidney disease. [45] Most cases of proteinuria are caused by increased levels of albumin , [ 61 ] which test strips can detect relatively well; but they are markedly less sensitive to other proteins, such as Bence-Jones protein , [ 62 ] which may ...
The normal number of red blood cells in urine should not usually exceed 3 per high power field. [13] A urine test strip showing positive for blood can also indicate hemoglobinuria, which is not detectable using a microscope due to the lysis of red blood cells in the urinary tract (particularly in alkaline or dilute urine), or intravascular ...
Nitrates are produced by a number of species of nitrifying bacteria in the natural environment using ammonia or urea as a source of nitrogen and source of free energy. Nitrate compounds for gunpowder were historically produced, in the absence of mineral nitrate sources, by means of various fermentation processes using urine and dung.
7. Soy Can Affect Fertility in Men. Soy has come a long way. Once dismissed as “hippie food,” today it’s a popular protein alternative for vegetarians and vegans.
Chemical screening methods for bacteriuria, such as, urine nitrate and glucose do not always detect S. saprophyticus infection. This is because unlike Gram-negative Enterobacteriaceae urinary tract infections, S. saprophyticus does not reduce nitrate and has a longer generation time, thus does not consume glucose as rapidly.
