Ahmed S, Kaplan A. Therapeutic Plasma Exchange Using Membrane Plasma Separation. Clin J Am Soc Nephrol. DOI: 10.2215/CJN.12501019. PMID: 32312791. Estimated plasma volume in liters is 0.065 times weight in kilograms times (1 minus hematocrit as a fraction). The usual exchange prescription is 1 to 1.5 times that volume. One plasma volume is described as lowering pretreatment immunoglobulin by about 63%, and 1.4 plasma volumes by about 75%. (2020)
