Urinalysis Interpreter Calculator

A urine dipstick test uses reagent pads that change color on contact with specific substances, giving a fast semi-quantitative readout of specific gravity, pH, protein, glucose, blood, leukocyte esterase, nitrite, and ketones without needing a lab analyzer. This calculator organizes those eight dipstick results into three summary signals. First, it flags each value that falls outside a commonly-used reference range (specific gravity 1.005-1.030, pH 4.5-8.0, and any positive protein, glucose, blood, leukocyte esterase, nitrite, or ketone reading) and totals how many are abnormal.

Second, it estimates hydration status purely from specific gravity, since a more concentrated urine (higher specific gravity) generally reflects reduced fluid intake or dehydration, while a more dilute urine (lower specific gravity) suggests overhydration or a kidney concentrating problem. Third, it flags a possible urinary tract infection when either leukocyte esterase or nitrite comes back positive -- leukocyte esterase detects white blood cells recruited to fight infection, while nitrite detects a byproduct that only certain UTI-causing bacteria (like E. coli) produce, so the two together catch a broader range of infections than either alone, though neither is definitive without a urine culture. A dipstick is a screening tool, not a diagnosis: a positive result on any of these panels should prompt confirmatory testing (microscopy, culture, or repeat testing) rather than treatment decisions based on the dipstick alone.
