After receiving a 24-hour urine for D (measure the total volume)
quantitative total protein analysis, the
tech must first:
A. subcultured the urine for bacteria
B. add the appropriate preservative
C. screen for albumin
D. measure the total volume
False results in urobilinogen testing A (exposed to light)
may occur if the urine specimen is:
A. exposed to light
B. adjusted to a neutral pH
C. cooled to room temp
D. collected in a non sterile container
A clean-catch urine is submitted to the B (be rejected due to the time delay)
lab for routine UA and culture. The
routine UA is done first, and 3 hours
later, the specimen is sent to the micro
dept for culture. The specimen should:
A. be centrifuged, and the
supernatant cultured
B. be rejected due to the time delay
C. not be cultured if no bacteria are
seen
D. be processed for culture only if the
nitrate is pos
,Which of the following urine results is D (bilirubin)
most apt to be changed by prolonged
exposure to light?
A. pH
B. protein
C. ketones
D. bilirubin
Urine samples should be examined C (bacterial contamination will cause alkalization of
within 1 hour of voiding because: the urine)
A. RBC's, leukocytes and casts
agglutinate on standing for several
hours at room temp
B. urobilinogen increases and bilirubin
decreases after prolonged exposure
to light
C. bacterial contamination will cause
alkalization of the urine
D. ketones will increase due to
bacterial and cellular metabolism
A urine specimen comes to the lab 7 B (at 4-7ºC)
hours after it is obtained. It is
acceptable for culture only if the
specimen has been stored:
A. at room temp
B. at 4-7ºC
C. frozen
D. with a preservative additive
,Which of the following would be C (pH)
affected by allowing a urine specimen
to remain at room temp for 3 hours
before analysis?
A. occult blood
B. specific gravity
C. pH
D. protein
Failure to observe RBC casts in a urine B (centrifuging an unmixed specimen)
specimen can be caused by:
A. staining the specimen
B. centrifuging an unmixed specimen
C. mixing the sediment after
decantation
D. examining the sediment first under
low pressure

in:
A. mg/dL
B. mg/24 hours
C. mL/min
D. mL/24 hours
Microalbumin can be measured by a B (nephropathy)
random urine collection. An increased
microalbumin is predictive of:
A. diabetes mellitus
B. nephropathy
C. hypertension
D. nephrotic syndrom
, A patient with uncontrolled diabetes A (pale urine with a high specific gravity)
mellitus will most likely have:
A. pale urine with a high specific
gravity
B. concentrated urine with a high
specific gravity
C. pale urine with a low specific
gravity
D. dark urine with a high specific
gravity
While performing an analysis of a A (phenylpyruvic acid)
baby's urine, the tech notices the
specimen to have a "mousy" odor. OF
the following substances that may be
excreted in urine, the one that MOST
characteristically produces this odor
is:
A. phenylpyruvic acid
B. acetone
C. cliform bacilli
D. porphyrin
Urine that develops a port wine color B. (porphyrins)
after standing may contain:
