There are a lot of them, in fact, some blood tests require the blood be collected in a cold vial, therefore, certain vials are stored in the refrigerator or freezer, depending on the specific requirements.
Some need to be stored at room temperature and others immediately frozen and kept frozen until ready for testing.
Due to the amount of blood tests available, it would be almost impossible to answer which ones need to be kept cold.
