✓ Correct answer: C. Red. The color of the top of a collection tube indicates the types of tests a specimen may undergo. Red-topped tubes are used for specimens that will undergo serology tests on serum, including the Monospot. These tubes are also used for specimens that will undergo chemistry tests on serum.
