When doctors draw blood for analysis, it’s vital that the sample either be immediately examined or refrigerated. That’s because the proteins which indicate various diseases will either be destroyed by enzymes in the blood or deformed by ambient heat. Either way, the sample quickly becomes useless if you leave it sitting out.
