A color change on a urinary tract infection (UTI) test strip, typically to shades of pink or purple, indicates the presence of nitrites. This chemical change occurs when bacteria, often associated with UTIs, convert nitrates normally found in urine into nitrites. A test yielding such a color shift suggests a possible infection and warrants further investigation by a healthcare professional.
Rapid and affordable at-home testing allows individuals experiencing potential UTI symptoms, like painful or frequent urination, to quickly assess the possibility of an infection and seek appropriate medical attention promptly. Early detection facilitated by these tests can contribute to faster treatment and potentially prevent more serious complications. While not a definitive diagnosis, these tests play a valuable role in preliminary assessment and guiding subsequent healthcare decisions.
