A Urine Specimen Obtained from a Patient Went to the Microbiology

A urine specimen obtained from a patient went to the microbiology lab for a bacterial culture and antibiotic sensitivity testing.The specimen sat out on the processing counter for a couple of hours before being cultured.Twenty fours hours later, the lab report goes into the computer---over 100,000 bacterial cells per milliliter of urine.Which statement is an accurate assessment of these results?

A) The bacterial count is not accurate since the culture sat without refrigeration.
B) Not all bacteria will grow on bacteriological media, so the total count is grossly underestimated.
C) Urine samples have to be taken from the kidney in order to get a true bacterial count.
D) Urine is a sterile fluid as it leaves the body, so it is likely that the specimen was mishandled by the nursing staff when the sample was obtained.
