An ammonia-like odor is characteristically associated with urine from patients with:

Urine that develops a “port wine” or deep red color after standing may contain:

Which of the following collection methods would yield the most sterile urine sample?

Urine from a 50-year-old patient with severe hepatic disease is reported as having an “amber” or dark brown color. The color of the sample is most likely caused by the presence of:

The clarity of a urine sample should be determined after:

A bright orange urine from a 24-year-old patient with cystitis likely contains:

After standing, a urine sample that develops a black coloration would most likely contain:

The yellow color of urine is primarily due to the presence of:

Following a severe crush injury, a patient is transported to the emergency room where a blood sample and a urine sample are collected. The patient’s urine sample appears reddish-brown, which may be due to the presence of:

A random urine specimen collected shortly after the patient ate lunch appeared cloudy. Results of the reagent test strip were normal. The most likely cause of the sample’s turbidity is the presence of:
