I en undersøgelse, hvor styrken af ReFacto AF, ReFacto og FVIII- aktiviteten i patientplasma blev målt under anvendelse af den kromogeniske substratanalyse, viste det sig, at ReFacto AF var bioækvivalent med ReFacto.
In a study in which the potency of ReFacto AF, ReFacto and FVIII activity in patient plasma were measured using the chromogenic substrate assay, ReFacto AF was shown to be bioequivalent to ReFacto.
