PROBLEM TO BE SOLVED: To provide a blood specimen collecting card by which the measured value as close as possible to the measured value of fresh blood can be obtained, and the measuring accuracy of serum-protein value, blood sugar value, prostate- specific acid phosphatase (PSA) value, hemoglobin Alc(Hb Alc) in which the measured values are affected by hemolysis, is improved. SOLUTION: The card is made up of a porous film 2 with its pores of 1 to 3μm in diameter formed in the porosity rate of 4 to 20% on the surface of a card-like filter paper 1 impregnated with a glycolysis blocking material, and formed of hydrophilic resin made of, for example, polyethylene terephthalate or polycarbonate. A blood sample collecting card on which a porous film 3 coated or impregnated with a blood coagulation blocking material is lapped over to the bonded and fixed, is favorable. The examination of Hb Alc, etc., can be accurately performed by using only blood corpuscles adhered to the surface of the porous film 3, and since the blood corpuscles are not contained and few hemolysis occurs in the liquid-component absorbed by the card-like filter paper 1, the biochemical examination of blood serum value, blood sugar value, etc., which tend to be affected by hemolysis, can be exactly performed.
