Urine Protein (Dipstick)
This dipstick test checks for protein, mainly albumin, in your urine. Healthy kidneys normally keep most protein in the bloodstream, so little appears in urine.
Protein in the urine is one of the earliest and most useful signals of how well the kidneys' filters are working. Small, temporary amounts can appear after exercise, fever, or stress, but persistent protein can be an important early clue about kidney health. Catching it early gives you and your clinician a head start on protecting kidney function.
A positive result means protein is present, which can be a passing response to exercise, fever, dehydration, or stress, or can reflect the kidneys' filters leaking protein, something a clinician may confirm with repeat or quantitative testing.
A negative or trace result means little to no protein was detected, which is the normal, reassuring finding for most people.
Negative is the expected result. Because protein can appear temporarily, a positive dipstick is typically rechecked and, if it persists, evaluated further by a clinician alongside your kidney numbers.
