CAMP test

This is an example of a positive CAMP test indicated by the formation of dark arrowheads where the Strep group B (Streptococcus agalactiae) meets the Staphylococcus aureus (light-yellow/golden middle streak with surrounding dark hemolysis).
Example of a workup algorithm of possible bacterial infection in cases with no specifically requested targets (non-bacteria, mycobacteria etc.), with most common situations and agents seen in a New England community hospital setting. CAMP test is shown at bottom left.

The CAMP test (Christie–Atkins–Munch-Peterson) is a test to identify group B β-hemolytic streptococci (Streptococcus agalactiae)[1][2] based on their formation of a substance, CAMP factor,[3] that enlarges the area of hemolysis formed by the β-hemolysin elaborated from Staphylococcus aureus.
