Which of the following conditions can lead to ineligibility for blood donation?

Anemia or low hemoglobin levels is indeed a condition that can lead to ineligibility for blood donation. The reason for this is that blood donors must meet certain health criteria to ensure that their donation does not pose a risk to their own health or that of the recipients. Donors with anemia, characterized by low hemoglobin levels, may not have sufficient healthy red blood cells to safely donate blood without experiencing adverse health effects. This is vital because blood donation can temporarily reduce the body’s oxygen-carrying capacity, and an individual with already low hemoglobin may suffer from symptoms like fatigue, weakness, or additional cardiovascular stress if they donate.

The focus on maintaining a safe donor pool underscores the importance of ensuring that all donors have adequate hemoglobin levels prior to donation, contributing to the wellbeing of both donors and recipients in the blood banking process.
