Rumor Refutation：8 Rumors About Voluntary Blood Donation

Rumor 1 :Blood drawing requires fasting, and so does blood donation.

/✗:This is a wrong statement

Blood drawing for tests usually requires fasting, but blood donation is different and does not necessitate fasting. On the contrary, donating blood on an empty stomach can lead to low glucose levels in the blood, potentially causing adverse reactions such as dizziness due to hypoglycemia.

To ensure that blood donors are in good physiological condition during donation and to avoid excessively high plasma lipid levels due to excessive nourishment, donors should maintain a light diet and sufficient sleep the day before donating blood.

Rumor 2 : Donating blood voluntarily can lead to illness.

/✗:This is a wrong statement

One reason some people hesitate to donate blood is the fear of infection. However, the blood collection needles, blood bags, and consumables used by current blood collection agencies are all qualified products that have undergone national quality inspection and strict sterilization and disinfection.

The principle of “one needle per person” is strictly enforced, with needles disposed of after use and consumables undergoing centralized (harmless disposal). Therefore, donating blood at a formal blood bank is safe and will not transmit diseases.

Rumor 3 :Blood donation can cause anemia.

/✗:This is a wrong statement

Human blood has a regenerative function. After donating a small amount of blood, the missing blood cells will be quickly replenished through the body’s self-regulation, and anemia will not occur.

Rumor 4 :Replenishing nutrition after blood donation can lead to obesity.
