Plasma is the liquid component of blood, containing proteins, antibodies, and other substances essential for various medical treatments. It is used to create life-saving therapies for individuals with conditions like immune deficiencies, bleeding disorders, or those recovering from severe trauma or burns. Donor health is crucial for the safety and effectiveness of the plasma product.
Pre-Donation Health Screening
Before each plasma donation, individuals undergo a health screening process. This typically involves completing a detailed medical history questionnaire, where donors answer questions about their recent health, medications, and travel history. Truthful answers are essential to determine suitability for donation.
A trained medical professional then conducts a physical assessment, checking vital signs like temperature, blood pressure, and pulse. A small blood sample is also taken to evaluate protein and hemoglobin levels and screen for certain viruses. First-time donors receive a more in-depth physical exam, repeated annually. These checks identify health issues that could make donation unsafe for the donor or compromise the plasma.
Potential Effects on the Donor
Donating plasma while ill can have direct consequences for the donor. The body is already fighting an infection, which places a strain on its resources and immune system. Symptoms like fatigue, body aches, or dehydration, common with a cold or flu, can worsen. Plasma donation removes fluids, which can exacerbate dehydration and increase fatigue.
Donors might experience discomfort during or after the procedure, including lightheadedness or dizziness. Recovery could be prolonged as the body diverts energy to combat the illness. Donating while sick temporarily reduces certain proteins and antibodies, further impacting the body’s ability to recover from infection.
Impact on Plasma Recipients and the Plasma Supply
Donating plasma while unwell carries significant implications, affecting vulnerable recipients and the overall plasma supply. Many plasma-derived therapies are given to immunocompromised patients, whose weakened immune systems make them susceptible to infections. Even a minor illness in a donor could introduce inflammatory markers or pathogens into the plasma, posing a risk.
If plasma is collected from a sick donor, it may be unsuitable for therapeutic use. Such plasma must be discarded, resulting in a loss of valuable medical resources. This creates a burden and can delay essential treatments for patients who rely on these medications. While plasma undergoes testing, honest self-reporting by donors remains the primary defense against contamination, ensuring safety and availability.
Responsible Donation Practices
To ensure the safety of both donors and recipients, responsible donation is important. Individuals should refrain from donating plasma if they are experiencing any symptoms of illness, such as a cold, flu, fever, severe cough, or sore throat. It is also important to avoid donating if one has recently recovered from an illness, even if symptoms seem mild.
General guidelines suggest waiting 24 to 48 hours after all symptoms of a mild cold have resolved before donating. For more severe illnesses, especially those with fever or body aches, a waiting period of at least one week after full recovery is recommended. If symptoms develop shortly after a donation, donors should contact the collection center to inform them.
