PLASMA
Subject : Science & tech
Context : Demand for plasma increases amid Covid case spike but donations low
Concept :
- Plasma is the liquid part of the blood.
- Convalescent plasma, extracted from the blood of patients recovering from an infection, is a source of antibodies against the infection.
- The therapy involves using their plasma to help others recover.
- For Covid-19, this has been one of the treatment options.
- The donor would have to be a documented case of Covid-19 and healthy for 28 days since the last symptoms.
Convalescent plasma therapy
- Convalescent plasma therapy uses blood from people who have recovered from an illness to help others recover.
- Blood donated by people who have recovered from Covid-19 has antibodies to the virus that causes it.
- The donated blood is processed to remove blood cells, leaving behind liquid (plasma) and antibodies. These can be given to people with Covid-19 to boost their ability to fight the virus.
