Answer to Question 1

ANS: C
The most significant improvement in automated coagulation analyzers is the ability to provide random access testing. This means that a variety of tests can be run in any order on the same plasma specimen or many specimens within the same testing batch. This vastly improves the efficiency of the clinical laboratory.

Answer to Question 2

ANS: B
Increased precision on the new automated coagulation instruments means that single-sample testing is possible. Before this, every sample had to be tested in duplicate and the duplicates had to agree within certain preset limits before they could be averaged and the result reported.
