Question

which of the followings presence in urine can indicate a urinary tract infection? a.) glucose b.) leukocytes c.) low ph d.) dark urine color

Explanation:

Leukocytes, also known as white blood cells, are part of the immune system. When there is a urinary tract infection (UTI), the body sends leukocytes to the area to fight the infection. As a result, their presence in urine (leukocyturia) is a common indicator of a UTI.

• Glucose in urine (glycosuria) is more commonly associated with diabetes or other metabolic disorders rather than UTIs.
• A low pH in urine can be due to various factors like diet (e.g., high - protein diet) or certain metabolic conditions, not specifically UTIs. In fact, some bacteria that cause UTIs (like Proteus) can raise the urine pH.
• Dark urine color can be due to dehydration (concentrated urine), liver problems (bilirubinuria), or other non - UTI related issues.

Answer:

B. Leukocytes
