Bands/Stabs. Early in the response to infection, immature forms of neutrophils will be seen. These are call Stab or Band cells. The presence of these immature cells is called a shift to the left and can be the earliest sign of a WBC response, even before the WBC becomes elevated.

Overall, the sensitivity of the urine dipstick test for nitrites in testing for a UTI has been found to be low (45-60% in most situations) with higher levels of specificity (85-98%). The test for nitrites has its highest accuracy in specific populations such as pregnant women, urology patients and elderly people.
