Abstract
Disclosed are a method for whole blood filtration and a filter membrane structure for whole blood filtration, specifically including the following steps: (1) a filter membrane structure made up of at least two filtration membranes sequentially stacked from top to bottom is selected, and subjected to hemagglutinin treatment for later use; (2) a whole blood sample is added to the filter membrane structure for filtration; and (3) the filtered serum or plasma is collected. The filter membrane structure is composed of at least two filtration membranes stacked from top to bottom, and the pore sizes of the filtration membranes stacked gradually decrease from top to bottom, and the areas of the same gradually increase or are equal to each other from top to bottom.
