Všechna onemocnění prodělaná během života je nutno uvést před odběrem krve – viz Dotazník pro dárce. Další formality a vyšetření provedeme na transfúzním oddělení bezprostředně před odběrem krve. Darování krve může být uskutečněno pouze v případě vyhovujících výsledků těchto vyšetření.

The suitability for donation will be decided by the doctor of the transfusion department on the basis of the facts you have provided.
