  • What is Tissue Donation? (giftofhope.org)
  • With a view to encouraging cadaver donations, Prof Kahn emphasised on the need to educate public on brain stem death and organ donation. (tribuneindia.com)
  • He pointed out that in most of the developing countries like India the concept of brain death was not clear and the people were are also not willing to accept the idea of organ donation. (tribuneindia.com)
  • In order to facilitate organ and tissue donation to meet the shortage of organs, Prof Kahn stressed on the need to encourage people to talk of brain stem death under normal circumstances so that no time was lost before the organs were removed. (tribuneindia.com)
  • For blood and tissues, the screening is more stringent, and any risk for infection found, either through behavior history or laboratory testing, results in the donation being declined. (cdc.gov)
