What does 100000 CFU mL mean?

Asymptomatic bacteriuria is defined as the presence of more than 100,000 CFU per mL of voided urine in persons with no symptoms of urinary tract infection. The largest patient population at risk for asymptomatic bacteriuria is the elderly. Up to 40 percent of elderly men and women may have bacteriuria without symptoms.

What is the normal range of urine test?

How do you get bacteria in your urine?

If your urine shows signs of bacteria or other organisms, you will receive a positive result. If few bacteria or organisms appear, you will receive a negative test result.
