How epidemic-related emergency reagents differ from regular scientific kits

During the pandemic, I noticed that the kits we were ordering for urgent diagnostics came way faster but felt different from what we normally use in the lab. For example, the packaging was simplified, and the protocols were stripped down to save time. In routine research we usually get more detailed instructions and sometimes extra reagents. I wonder if others saw a clear difference between emergency orders and the standard scientific kits we’re used to.
