blodläggning

Blodläggning, a Swedish term for blood donation, refers to the voluntary act of giving blood to be used for medical treatments such as surgeries, cancer therapy, and emergency care. The practice is regulated by the Swedish Blood Service (Svenskt Blod, also known as BloodBank Sweden), which ensures that donations are safe for both donor and recipient.

The modern blood donation system in Sweden began in the 1940s, with a structured national registry that tracks donors and inventory. Over time, the Swedish Blood Service has expanded programs to include plasma and platelets, enabling treatments for critical conditions like severe bleeding and coagulation disorders.

Eligibility for blodläggning is based on health, age, and weight criteria. Generally, donors must be between 18 and 65 years old, weigh at least 50 kilograms, and be in good health without recent illnesses or surgeries that could affect blood quality. Certain vaccinations, medications, and travel histories can temporarily defer donation. The donation process involves a brief health screening, a blood draw of about 500 milliliters, and a short recovery period, usually less than an hour.

Donated blood is tested for infectious diseases such as HIV and hepatitis, and is processed into components—red cells, platelets, plasma—to maximize therapeutic use. Approximately 1 in 200,000 Swedish citizens donate regularly, contributing to a stable supply that supports the nation's healthcare needs. The importance of blodläggning is underscored during periods of high demand, such as natural disasters or mass casualty events. Volunteer donors receive a small food allowance and may also receive medical check-ups, fostering a culture of community health.
