True of cholesterol metabolism, except
A. free cholesterol is the inactive form of
cholesterol with cytotoxic property
B. Free cholesterol and phospholipids
have a hydrophilic property
C. both have hydrophilic and
hydrophobic properties
D. the process of esterification is a
“detoxification” step cholesterol ester
is almost 90% in plasma
B. Free cholesterol and phospholipids
have a hydrophilic property
It is the recommended fasting hour in
most clinical biochemistry tests: 6-8 hours
8-12 hours
True of R4s, except:
A. it is caused by random errors
B. it is observed after 2 consecutive
days
C. R means random error
D. difference between the highest and
lowest control result exceeds 4s
B. it is observed after 2 consecutive
days
It is the ideal reference limit:
2s
It is the most abundant lipid in human
plasma:
Cholesterol
True of creatinine, except:
A. a measure of the completeness of
24-hour urine collection
B. plasma creatinine may not be
increased until renal function has
deteriorated more than 50% plasma
creatinine is usually within the
reference limit in muscular diseases
C. in muscular dystrophy, plasma
creatine is decreased while urinary
creatinine is elevated
C. in muscular dystrophy, plasma
creatine is decreased while urinary
creatinine is elevated
Control values are computed based on: 1.mean
2. median
3. standard deviation
4.variance
1 and 3
if urea is the most abundant NPN in
plasma, ______________ is the least in concentration. creatine
Ammonia
Safety glasses, face shields or other eye
protectors must be worn when:
working with toxic materials
Observable symptoms of hypoglycemia can be observed when plasma glucose reach this level
plasma glucose level ≤55 mg/dL (3.0
mmol/L);
It is a subset of molecular luminescence
spectrometry and measures the amount of light intensity present over a zero
background:
Fluorometry
This method is based on the measurement f scattered light and is ideal for quantitative analysis of immunoglobulins:
Nephelometry
Serum urea levels drop in severe hepatic diseases, therefore, low BUN is not generally considered abnormal renal function
only the second is correct
True of diagnostic specificity, except
it generates more true-positive
results
Primary function of serum albumin in the peripheral blood is to
maintain colloidal osmotic
pressure
True of the ion-selective electrode, except
indirect ISE requires sample
dilution
It refers to the closeness of assayed values
Precision
It is known as the rapid serum tube
since clotting of blood would take
place within 5 minutes: pearl white
top
Orange top
This hormone which is released from the islet cells of the pancreas inhibits insulin
Glucagon
It is the reference method in the
determination of lipoproteins:
ultracentrifugation

patient should have consumed at least 150 grams/day of carbohydrates for 3 days prior to testing
is the reference method in the
measurement of renal NPNs:
IDMS notsure
It is the only protein with enzymatic activity
transferrin
Earliest NPN to rise in plasma in cases of
kidney diseases:
Urea
