Urine dipstick

Definition

A urine dipstick is a diagnostic tool used to detect abnormalities in a urine sample. It provides quick results for substances like proteins, glucose, and bacteria which can indicate infections or other medical conditions.

5 Must Know Facts For Your Next Test

1. Urine dipsticks can identify the presence of nitrites, which are often produced by gram-negative bacteria like E. coli.
2. Leukocyte esterase detected on a dipstick suggests white blood cells in the urine, indicative of an infection.
3. Proteinuria detected on a dipstick may suggest kidney involvement or damage due to an infection.
4. The presence of blood on a dipstick can indicate hematuria, which may result from urinary tract infections or other urogenital issues.
5. Dipsticks can also test for pH levels, which might be altered during bacterial infections.
