Choose the correct statement regarding chromogenic analysis in hemostasis testing from the following choices.
A) Chromogenic analysis depends on the selected analyte's ability to cleave a chromophore.
B) Chromogenic analysis is not subject to preanalytical problems because of its mechanism of clot detection.
C) There is no difference between chromogenic analysis and electromechanical detection.
D) Chromogenic analysis depends on the optical detection of ball movement through a steel tube as a clot forms.

Question

Quizplus · Accepted Answer

Chromogenic analysis relies on the ability of an analyte to cleave a chromophore, which then leads to a change in color that can be detected optically. Option B is incorrect because chromogenic analysis may be subject to preanalytical problems such as interference from lipemia or hemolysis. Option C is incorrect because chromogenic analysis and electromechanical detection are different methods of clot detection. Option D describes the mechanical clot detection method, not chromogenic analysis.
