This invention provides bovine pregnancy test methods and devices. The test is also suitable for other ruminant and/or ungulate animals. Antigens from Group A (early pregnancy antigens), and/or Group B (mid-pregnancy antigens), and Group C (early, mid- and late pregnancy antigens) are detected in a
This invention provides bovine pregnancy test methods and devices. The test is also suitable for other ruminant and/or ungulate animals. Antigens from Group A (early pregnancy antigens), and/or Group B (mid-pregnancy antigens), and Group C (early, mid- and late pregnancy antigens) are detected in a fluid from the animal, and pregnancy is reliably determined. The pregnancy assays of this invention are preferably carried out using immunoassay devices which provide immediate results in the field.

We claim: 1. A method for determining pregnancy of a ruminant and/or ungulate animal, the method comprising: (a) testing a fluid or cell derived from said animal for the presence of at least one Group A antigen selected from the group consisting of interferon-tau induced proteins, Bovine Antigen Gl
We claim: 1. A method for determining pregnancy of a ruminant and/or ungulate animal, the method comprising: (a) testing a fluid or cell derived from said animal for the presence of at least one Group A antigen selected from the group consisting of interferon-tau induced proteins, Bovine Antigen Glycoprotein (BAG), Early Pregnancy Factor (EPF), Pregnancy Specific Protein B (PSPB). and Pregnancy Associated Glycoproteins 1, 4, 5 and 9 (PAG-1, PAG-4, PAG-5, and PAG-9 or Group B antigen selected from the group consisting of estrone sulfate, pregnancy serum protein 60 (PSP-60 pregnancy-associated glycoproteins 6 and 7 (PAG-6 and PAG-7), and pregnancy-specific protein B (PSP-B); (b) testing a fluid or cell derived from said animal for the presence of progesterone; (c) determining that the animal is pregnant if testing is positive for the presence of at least one of said Group A or Group B antigens and progesterone; and (d) determining that the animal is not pregnant if testing is negative for the presence of progesterone. 2. The method of claim 1 wherein the animal is selected from the group consisting cattle, sheep, goats, yak, water buffalo, bison, antelopes, gazelles, elk, reindeer, moose, bighorn sheep, swine, horses, giraffes, bactrian and dromedary camels, llamas, alpacas, and vicunas. 3. The method of claim 1 wherein the animal is a cow. 4. The method of claim 1 comprising testing said fluid for the presence of at least one of said Group A antigens and at least one of said Group B antigens. 5. The method of claim 1 wherein testing for the presence of said Group A or Group B antigen is done by means of contacting said fluid with an antibody for said antigen. 6. The method of claim 5 wherein said antibody is a polyclonal antibody. 7. The method of claim 5 wherein said antibody is a monoclonal antibody. 8. The method of claim 5 wherein said antibody is present on a test strip. 9. The method of claim 5 wherein antibodies for both said Group A and Group B antigens are on the same test strip. 10. The method of claim 1 wherein testing for the presence of progesterone is done by means of contacting said fluid with an antibody for progesterone. 11. The method of claim 10 wherein said antibody is a polyclonal antibody. 12. The method of claim 10 wherein said antibody is a monoclonal antibody. 13. The method of claim 10 wherein said antibody is present on a test strip. 14. The method of claim 10 wherein antibodies for said Group A or Group B antigens are on the same test strip with antibodies for progesterone. 15. The method of claim 1 wherein said Group A antigen is selected from the group consisting of ISG17, Mx, GCP-2, 2′,5′oligoadenylate synthetase, β2-microglobulin, IRF-1, IRF-2, I-8U, 1-8D and Leu-13/9-27, COX-2, BAG, EPF, PAG-1, PAG-4, PAG-5, and PAG-9. 16. The method of claim 1 wherein said Group B antigen is selected from the group consisting of PSPB, PSP-60, PAG-6, and PAG-7. 17. The method of claim 1 wherein said fluid is selected from the group consisting of whole blood, plasma, serum, urine, milk, nasal secretions, ocular secretions, vaginal secretions, saliva and cell lysates.
