How Dipsticks Work

Dipsticks are designed to detect substances in the urine that indicate infection. They measure leukocyte esterase, a marker for white blood cells, and nitrite, which can signal the presence of bacteria. These tests are quick and easy, often used in clinics when a UTI is suspected.

Accuracy of Dipsticks

The accuracy of dipsticks can vary. A positive result for both leukocyte esterase and nitrite is highly predictive of a UTI. However, false negatives can occur, especially if the urine hasn't been in the bladder long enough for bacteria to convert nitrates to nitrites. Other factors, like dietary supplements, can also affect results.
A dipstick test is a diagnostic tool used to detect urinary tract infections by measuring leukocyte esterase and nitrite levels in urine.

When to Use Dipsticks

Dipsticks are useful when symptoms of a UTI are present, such as frequent urination and burning sensations. They are less beneficial for asymptomatic patients since a positive result might not truly indicate a UTI. It's best to use them alongside other diagnostic methods for a more comprehensive assessment.
