What is urine dipstick chemical analysis?
A dipstick — a thin, plastic stick with strips of chemicals on it — is placed in the urine. The chemical strips change color if certain substances are present or if their levels are above typical levels. A dipstick test checks for: Acidity (pH).
What are the chemicals commonly tested for using a dipstick test?
Urinalysis dipsticks at the point-of-care Urinalysis dipsticks contain discrete reagent pads to semi-quantitatively test for the presence of bilirubin, blood, creatinine, glucose, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen in a urine sample.

What is used to perform a chemical analysis on a urine sample?
A special strip (dipstick) is used to test for substances in the urine sample. The strip has pads of chemicals that change color when they come in contact with substances of interest.
Are urine dipsticks accurate?
Overall, the results of dipstick analysis of urine are not as accurate as thought by many clinicians, and have a number of false-positive and false-negative results.
How long do urine dipsticks last?
This bottle may be used for one week for patient testing. If one or more of the urine control solutions fail to give expected results: 1. Check to make sure that the control solutions and urine dipsticks have not expired.
What is the normal chemical examination of urine?
Chemical examination of urine includes the identification of protein, blood cells, glucose, pH, bilirubin, urobilinogen, ketone bodies, nitrites, and leukocyte esterase. Finally, microscopic examination entails the detection of crystals, cells, casts, and microorganisms.
What do urine dipsticks test for?
It’s dipped into your urine, and the chemicals on the stick react and change color if levels are above normal. Things the dipstick test can check for include: Acidity, or pH. If the acid is abnormal, you could have kidney stones, a urinary tract infection (UTI), or another condition.
Can a dipstick be wrong?
Yes, some cars come from the factory with the wrong dipstick. If you are worried about yours, check it against that of another car with the same engine or with a replacement stick at the parts counter. And, sometimes oil clinging to the dipstick tube will cause an erroneous reading.

Which urine pH is considered neutral?
A pH of 7 is neutral, whereas a pH result below 7 is acidic and above 7 is alkaline. Urine has the highest range of pH compared to other bodily fluids. The American Association for Clinical Chemistry says the normal urine pH range is between 4.5 and 8.
What constitutes positive urine analysis?
A positive urinalysis is an inspection of a urine sample that yields a positive result for whatever the technician was looking for in the sample. In addition to reporting on whether a result is positive or negative, the technician may also provide information about the concentration…

It may also change color if other substances, such as glucose, white blood cells, bilirubin, or proteins, are present in the urine.
What does urine dipstick measure?
A urine dipstick is a colorimetric chemical assay that can be used to determine the pH, specific gravity, protein, glucose, ketone , bilirubin, urobilinogen, blood, leukocyte, and nitrite levels of an individual’s urine. It consists of a reagent stick-pad, which is immersed in a fresh urine specimen and then withdrawn.
