Patent ID: 7410807

Claim:
A method of testing a female animal for pregnancy, the method comprising the steps of: (a) providing a first liquid medium and then introducing a bodily fluid containing a hormone from the animal into said first liquid medium to provide a first liquid mixture contained in a first vessel having an opening and a removable cap adapted to close said opening, wherein said cap has an entirely substantially flat solid inner surface with antibodies attached thereto and contacting said first liquid mixture with the solid inner surface to provide a reaction wherein said hormone of said bodily fluid binds with at least some of said antibodies attached to said solid inner surface; (b) providing a reporter hormone solution containing a reporter hormone contained within a second vessel having an opening and adapted for receiving and being closed by said removable cap such that, upon placing said entirely substantially fiat solid inner surface of said removable cap in contact with the reporter hormone solution, a reaction is provided wherein said reporter hormone binds with any remaining antibodies attached to said solid surface; (c) contacting the entirely substantially flat solid inner surface with an indicating solution; and (d) then making a determination regarding pregnancy of the animal based on a change in color of either the solid inner surface or the indicating solution.
