nauseated and vomited 90
minutes after receiving a
standard 50g carbohydrate
dose for an oral glucose
tolerance test. what is the
best course of action?
which of the following 2 200 mg/dL
hour post prandial glucose
values demonstrates
unequivocal hyperglycemia
diagnostic for diabetes
mellitus?
155 mg/dL
170 mg/dL
185 mg/dL
200 mg/dL
a 41 year old woman had triglycerides are elevated, which may be attributed to
the following lab results 6 the recent meal
hours after eating
triglycerides- 280 mg/dL
cholesterol- 140 mg/dL
,in HDL-c analysis, cloudy or falsely increased HDL cholesterol
floating particulates in the
supernatant will most likely
cause which of the
following
which LDL-c level exceeds 168 mg/dL
the cutoff for coronary
heart disease high risk?
168 mg/dL
154 mg/dL
126 mg/dL
105 mg/dL
what reagent is added to caffeine-sodium benzoate
accelerate the diazo
reaction with conjugated
bilirubin to form a
chromogen
a serum total bilirubin cholestasis/cholelithiasis
concentration of 5.4 mg/dL
and a conjugated bilirubin
conc of 4.9 mg/dL with a 4+
urine bilirubin but a
negative urine urobilinogen
result is associated with
which of the following
hepatitis
hemolytic disease
gilbert disease
cholestasis/cholelithiasis
what is ht emost commonly immunoinhibition immunoassay
used method in clinical
laboratories for CKMB
testing
an oncology pt undergoing recurrence of colorectal cancer
treatment has a
carcinoembyonic antigen
(CEA) level of 15ng/mL
(reference range <10). what
does this indicate?
, interference due to using the kinetic jaffe method
glucose, ascorbate, and
alpha ketoacids can be
minimized in analysis of
creatinine by what?
a plasma ammonia result of hepatic failure
150 ug/dL (reference range,
19-55) in a pediatric patient
likely indicates which of the
following?
prehepatic disorders
prerenal disorders
renal failure
hepatic failure
when measuring thyroxine there is no separation or wash step
(T4) by fluorescent
polarization immunoassay,
which of the following is
true?
T4 binds to specific
antibody to t4 bound to
microtiter plate
there is no separation or
wash step
fluorescent-labeled drug
competes with patient T4
for polarized antibody
reaction time is slower than
radioimmunoassay (RIA)
but fluorescent polarization
immunoassay is more
common owing to safety
issues with RIA
