There is represented a system and a method providing therapeutic plasma protein dosing regime including determining pharmacokinetic profile of patient using Bayesian model of pharmacokinetic profiles of sampled patients. Example system and method also include determining first dosing regime for first specified dosing interval including first dosage and first therapeutic plasma protein level in the patient over time period based at least upon pharmacokinetic profile and determining second dosing regime for second specified dosing interval including second dosage and second therapeutic plasma protein level in the patient over time period based at least upon the pharmacokinetic profile. Example system and method further include displaying first dosing regime and second dosing regime on client device such that first dosing regime is displayed in conjunction with second dosing regime.
