What is a factor that may permanently disqualify someone from donating plasma at CSL Plasma?

A history of certain infectious diseases is a factor that may permanently disqualify someone from donating plasma at CSL Plasma because these diseases can pose significant health risks to both the donor and the recipients of the plasma products. Infectious diseases such as HIV, hepatitis B, or hepatitis C can be transmitted through blood and plasma, leading to severe health consequences for recipients. Plasma donation centers, including CSL Plasma, follow strict guidelines to ensure the safety of the donation process and the well-being of patients who receive these products.

In contrast, having a cold is typically a temporary condition and does not usually lead to permanent disqualification, as symptoms generally resolve quickly. Being over the age of 60 is not an automatic disqualification; age limits for donation may exist, but older individuals can often donate if they meet other health criteria. Having had a blood transfusion might lead to a temporary deferral depending on the circumstances, but it does not permanently disqualify someone unless there are specific concerns related to the transfusion that affect health status or safety.
