The availability of lyophilized (dried) factor VIII or factor IX concentrates allows home infusion therapy to become a common treatment practice

By the late 1960s, scientists and manufacturers developed methods for separating factor VIII and factor IX from pooled plasma, resulting in neatly packaged bottles of freezedried (lyophilized) factor VIII or factor IX concentrates. Each bottle had a label indicating the amount of factor VIII or factor IX it contained, allowing more accurate dosing. By the early 1970s, factor concentrate usage continues to vary. Some doctors are still prescribing and instructing patients to use cryoprecipitate in the early 1970s.

Advancements in Care

Treatment at home is becoming more prevalent and some patients no longer feel tethered to the hospital. For decades, hemophilia families have organized blood drives to replace the donations needed for transfusions. These remain common, despite the increasing availability of cryoprecipitate and clotting factor concentrates.
