World War II dried plasma (1940s)
The US pioneered dried plasma in World War II, shipping large quantities to field hospitals to treat shock and hemorrhage. The process pooled plasma from many donors.
Hepatitis outbreaks traced to pooled plasma led the US military to abandon dried plasma after the war.
The US shifted to frozen single-donor plasma with viral screening, while some foreign militaries kept freeze-dried plasma in use.
Ezplaz brings back a technology the US invented and abandoned, this time with single-donor sourcing and modern testing.
