In order to test whether the flu virus in a sample taken from a patient, matches an influenza vaccine virus, the sample needs to be grown in a cell culture, or an embryonated chicken egg. Growing the virus in cell culture, or eggs, produces a larger volume and concentration of virus than what was in the original sample. The larger volume of flu virus is needed for additional laboratory tests. These eggs had been injected with influenza virus, and were warming in an incubator. The warmth encourages influenza viruses to grow faster than they would at room temperature. The eggs stay in the incubator for two to three days, depending on the influenza viruses they contain. Influenza B viruses take a bit longer to grow with this method, compared to influenza A viruses.
