These Wrong negatives are due possibly towards the virus not replicating in the indicator cell lines chosen for your exam, to viral replication not causing measurable cytopathic influence from the picked out indicator cells, or to replication of your viral isolate taking place as well bit by bit to be detected by the end with the check. The IVV assay also will take fourteen to 28 times—A lot also lengthy to evaluate the reactor for contamination just before processing downstream for purification.
