A clinical laboratory receives a new lot of PTT reagent, so clinical laboratory scientists in the laboratory need to establish the heparin therapeutic range for this new reagent lot. How should this be done?
 
  a. Compare PTT results for patient heparinized samples to those for the lot of PTT reagent that is presently being used.
  b. Perform chromogenic Xa and PTT assays on patient heparinized samples, and do a statistical analysis of result comparisons.
  c. Add heparin at various therapeutic concentrations to normal plasma, and perform PTT on each concentration using the new lot of reagent.
  d. Add heparin at high concentration to one normal plasma, make dilutions of this plasma, and then perform PTT on each diluted sample using the new lot of reagent.
