control range for the laboratory is +/- 2 SD. Which of the following
represents the allowable limits for the control? -
correct answer ✅14.8-15.6 g/dL
In QC, +/- 2 SD from the mean includes what % of the sample
population -
correct answer ✅95%

range. What s the appropriate course of action -
correct answer ✅Run a new set of controls and repeat specimens
The following data were calculated on a series of 30 determination
of serum uric acid control:
mean=5.8mg/dL

result by a given test
If the correlation coefficient (r) of two variables is 0: -
correct answer ✅There is an absence of correlation
