Coagulase Test
A drop of physiological saline was put on a
clean glass slide, followed by making a smear of 24hrold
isolate of the test organism. Then a drop of human
plasma was added unto it to makes a suspension.
Clumping indicates positive result which implies the
ability of the test organism to produce coagulase, an
enzyme that coagulates blood plasma. While in a
negative result no clumping was observed [4].
