PREGNANCY DIAGNOSIS KIT

摘要

PURPOSE: A pregnancy diagnosis kit is provided to readily decide the pregnancy of a cow 19 or 20 days after fertilization by using the concentration of progesterone existing in blood. CONSTITUTION: A thin film type paper(1) forms a specific size of pores inside. A progesterone-BSA conjugate(2) of specific concentration is coated in a specific area on at least one face of the paper. A colloidal gold label(3) embedding anti-progesterone is combined with some part of an upper face of the progesterone-BSA conjugate. The concentration of progesterone existing in blood, progesterone-cow serum albumin fixed on a thin film and an anti-progesterone gold conjugate are competitively reacted. Color reaction is performed in reverse proportion to the progesterone concentration in the blood. Accordingly, the pregnancy of the cow is readily decided.
