Health officials say the Philippines has broken India's record of gathering the most number of organ donor pledges in an hour at a single site.
The feat is awaiting official confirmation from Guinness World Records.
Health Assistant Secretary Eric Tayag said today's campaign gathered 3,548 pledges, beating India's previous record of 2,755.
The event, held at the Polytechnic University of the Philippines' Manila campus, was aimed at raising awareness about organ donation.
Mr Tayag said the record so far set is still unofficial because there were no Guinness adjudicators present. Documented results will be sent to the records body.
