A doctor has provided 1 answer

Contaminant: Infection is when pathogens (bacteria for example) invade your tissues. This almost always produces signs which include redness, swelling, warmth and pain. In the absence of symptoms this is a contaminant or a colonization of your urinary tract. Note: Do not test urine without a good reason....
