A urine test strip or dipstick is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample..
Accordingly, what does a urine dip test show?
A dipstick — a thin, plastic stick with strips of chemicals on it — is placed in the urine to detect abnormalities. The chemical strips change color if certain substances are present or if their levels are above normal. A dipstick test checks for: Acidity (pH).
Subsequently, question is, what do they look for in urine test? The tests detect and/or measure several substances in the urine, such as byproducts of normal and abnormal metabolism, cells, cellular fragments, and bacteria. Some examples include glucose, protein, bilirubin, red blood cells, white blood cells, crystals, and bacteria.
Moreover, what shows up on a urine dipstick for UTI?
Dipstick testing should include glucose, protein, blood, nitrite, and leukocyte esterase. Leukocyte esterase is a dipstick test that can rapidly screen for pyuria; it is 57-96% sensitive and 94-98% specific for identifying pyuria.
What is a positive urine dip?
A positive nitrite test usually means infection. It generally requires more than 10,000 bacteria per ml to turn the dipstick positive, making it a specific but not a very sensitive test. A negative nitrite test does not rule out a UTI, but a positive one strongly suggests infection.

The presence of leukocyte esterase on dipstick may also be due to non-infectious renal diseases such as glomerulonephritis.What does it mean if you test positive for leukocytes in your urine?
Leukocytes may also be found in a urinalysis, or a urine test. High levels of WBCs in your urine also suggest that you have an infection. Usually, that means the bladder or the urethra, which is the tube that carries urine from the bladder.
