There are Eucharistic miracles still extant throughout the world, derived from the True (Latin) Mass. Some of these involve dried Precious Blood pills or pieces - maybe even other forms taken by the Precious Blood. But these miraculous Eucharist results have been reverently sealed or kept in beautiful reliquaries or ciboriums for the further worship and reparation of the faithful. With Ecclesiastical permission (some of) these have been known to be examined.
Maybe someone else knows more. Point being, there already has been research on the nature/substance of some of these Eucharistic phenomenon.
