Abstract
The blood filter unit of the invention is composed of a blood filtering material made of glass fiber filter and microporous membrane and a holder having a blood inlet and a filtrate outlet. The holder accommodates the blood filtering material so that the microporous membrane is located on the filtrate outlet side, provides a space between the blood filtering material and the filtrate outlet, and provides a means for preventing adhesion of the blood filtering material on the filtrate outlet side. By using the blood filter unit, a necessary volume of plasma or serum for analysis can be separated surely, irrespective of hematocrit value of the blood.
