Abstract
Red Blood Cells (RBC's) are removed from whole blood samples by contacting the whole blood sample with a solution containing an acid selected from the group consisting of acetic acid, citric acid, ascorbic acid, lactic acid, maleic acid, malic acid, and malonic acid. The agglutinated RBC's are then removed from the resultant suspension by procedures of filtration, centrifugation or decantation, leaving an essentially RBC-free serum or plasma sample.
