Abstract
A blood filter unit having a blood filter holder containing a blood filtering material of a glass fiber filter and a microporous membrane is described. The holder has a blood inlet and a filtrate outlet, and accommodates the blood filtering material so that the microporous membrane is located on the filtrate outlet side and has a space between the blood filtering material and the filtrate outlet. The holder provides means for preventing adhesion of the blood filtering material on the filtrate outlet side. The inventive blood filter unit allows separation of a desired volume of plasma or serum for analysis without interference by the hematocrit value of the blood.
