There is generally no specific weight requirement for blood donation. Individuals who are in good health and do not have other infectious diseases may donate blood at a hospital. However, those with frail constitutions or who are prone to hypotension should avoid donating blood, as it may adversely affect their health. Prior to donation, a routine blood test must first be performed at the hospital to rule out any abnormalities.
