The name of the test which can increase the accuracy of the identification of the organism is Coagulase testing.

Explanation:

Given the points stated in the question, the organism most likely under scrutiny here is Staphylococcus Aureus. Science has shown that it is the most harmful of all of the many different staphylococcal bacteria that there is.

The best test for differentiating and identifying Staphylococcus Aureus apart from other types of other Gram-positive cocci is the coagulase test.

The coagulase test checks to see if the microbe can produce an exoenzyme called coagulase.

Coagulase - an exoenzyme, is usually produced by bacteria. This enzyme triggers the coagulation of blood or plasma.

Only the pathogenic or disease-causing forms of staphylococcus can produce this enzyme. The enzyme is qualified by the suffice  "exo" because the enzyme is secreted externally and not internally. Also, its functions are external, not internal.

The Coagulase testing is of two types:

It is usually safer to use the test tube method. If one must rely on the slide test, the results must be read quickly as it is prone to false positives.
