Call ahead and confirm before travelling. Sourced from the Kerala State AIDS Control Society (KSACS) official blood bank listing. "Platelet donation (BCSU)" reflects each centre's official government designation as a Blood Component Separation Unit, not an independent phone check of current capacity -- call ahead before travelling, especially for a platelet (SDP) donation, which only a minority of these centres can actually collect.
