c. Precision
d. Reliability
B
Which of the following would be most adversely affected by a non-fasting sample?
a. HDL
b. LDL
c. Cholesterol
d. Triglycerides
d
Endo = VLDL

A nurse calls the laboraroty technologist on duty asking about blood collection fro the analysis of enzymes. Which of the following tubes would you suggest the technologist collect?
a. Red Top
b. EDTA
c. Oxalate
d. Fluoride
a
Enzymes = Cofactors (Accelerator)

According to NCEP, which lipid or lipoprotein class is more important for therapeutic decision making (Diet and Medication Decisions)
a. Chylomicrons
b. LDL
c. HDL
d. Cholesterol
B
HDL contains cardioprotective however it does not collerate disease such as CAD which is why LDL is used
As LDL increase You can predict CAD
