The compositions comprise chorionic gonadotropin coupled to animal red blood cells by means of glutaraldehyde as coupling agent therebetween as well as anti-chorionic gonadotropin serum and gelatin which has the effect of greatly increasing the shelf life and accuracy over prolonged periods of time of the composition. The body fluid of the female animal suspected of being pregnant is mixed with the above composition and permitted to stand. Agglutination indicates non-pregnancy whereas failure of agglutination indicates pregnancy. The invention further comprises that the specific use of turkey blood or camel blood as the source of the red blood cells, the use of either turkey blood or camel blood greatly reducing the time required for the testing.
