An unidentified fluid is received in the laboratory with

a request to determine if the fluid is urine or another

body fluid. Using routine laboratory tests, what tests

would determine that the fluid is most probably urine?

A patient presenting with polyuria, nocturia, polydipsia,

and a high urine specific gravity is exhibiting

symptoms of what disorder?

A urine specimen for routine urinalysis would be

rejected by the laboratory because:

An unpreserved specimen collected at 8 a.m. and

remaining at room temperature until the afternoon

shift arrives can be expected to have:

1. Decreased glucose and ketones

2. Increased bacteria and nitrite

3. Decreased pH and turbidity

4. Increased cellular elements

What three changes will affect the results of the

microscopic examination of urine if it is not tested

within 2 hours?

What is the specimen of choice for routine urinalysis?

A negative urine pregnancy test performed on a random

specimen may need to be repeated using a:

Cessation of urine flow is termed:

Three types of urine specimens that would be acceptable

for culture to diagnose a bladder infection

include all of the following except:

The concentration of a normal urine specimen can be

estimated by which of the following?

A urine that turns black after standing may contain:

Specimens that contain intact RBCs can be visually

distinguished from those that contain hemoglobin

because:

The method for determining a urine specific gravity

that is based on the principle that the frequency of a

sound wave entering a solution changes in proportion

to the density of the solution is:

A strong odor of ammonia in a urine specimen could

indicate:
