Chronic kidney disease is defined by the Kidney Disease Outcomes Quality Initiative of the National Kidney Foundation as a:
 
  A) glomerular filtration rate of less than 60 mL/min for 3 months or more.
  B) glomerular filtration rate of less than 100 mL/min for 3 months or more.
  C) glomerular filtration rate of less than 40 mL/min for 6 months or more.
  D) glomerular filtration rate of less than 120 mL/min for 3 months or more.

Question 2

A laboratory staff member is interested in evaluating a new technology (Optode) for measuring potassium in serum. The technologist performs a split sample study by measuring potassium using their current method, ISE, and the new method.
 
  Determine the slope and intercept using a linear regression by least-squares analysis. Also calculate the Pearson product-moment correlation coefficient.
  Which of the following responses reflects the correct values for each calculated parameter?
 
  Sample  Potassium (ISE) reference method (meq/L) - x-axis Potassium (Optode) new method (meq/L) - y-axis
  1 4.5 4.7
  2 2.4 2.7
  3 7.4 7.6
  4 10.1 10.2

  22 4.0 4.0
  23 4.5 4.6
  24 2.5 3.0
  25 7.0 7.0
 
  A) Slope: 1.02, intercept: -0.283, correlation coefficient: 0.998
  B) Slope: 0.976, intercept: 0.290, correlation coefficient: 0.998
  C) Slope: 0.976, intercept: -0.283, correlation coefficient: 0.998
