Answer:
The following parameters of blood donors have to be checked prior blood donation:
1. Age – It is important to check the age of an individual before he/she donates blood. This is because there is a set age before which and after which blood donation can be done or not, respectively.
2. Weight – Weight of individuals is a key parameter of blood donation as underweight individuals are not allowed to donate blood. In underweight individuals, there are chances that the donor may face unnecessary consequences or have a reaction such as dizziness and fainting, if blood donated is in higher quantity.
3. Heart, lungs and other blood disorders – Whenever a donor goes for donating blood, his/her prior history of heart, lungs or blood diseases are thoroughly enquired. People with heart valve conditions, heart disease, irregular heartbeat, anaemia, heart failure, and certain lung conditions are excluded from blood donation. Certain blood diseases such as iron deficiency or chronic leukemia or HIV +ve are also excluded from blood donation.
4. Other medical conditions –Extreme medical conditions such as hypotension, diabetes, hypertension, fever etc. are also checked before blood donation to prevent it from transfusing the blood to a person in need.
5. Recent surgery – People with recent surgery history are also not allowed to donate blood. However, after a year of surgery they can donate blood if they wish but only if they’ve recovered or healed completely and they are capable of resuming full activity like a healthy human being.
6. Pregnancy – Pregnant women are not permitted to donate blood during pregnancy and for at least six weeks after the pregnancy ends.
