Would a human pregnancy checker (from the drug-store) work for a horse?

Question

I only ask this out of pure curiosity as it came up in a discussion with some friends. Surely any pregnancy checker looks for the same hormone variants when detecting pregnancy.
Does anyone have an accurate answer for this one?

Just for reference I am not talking about pregnancy checking my mares this way.

Answer 1

Sorry, no. The test for horses is looking for the positive presence of eostren sulfate, not HcG, as in humans. It used to only be tested for by blood or by urine sample, but now can be tested in horses by a sample of fresh feces, with test results available in a few days (rather than a week or more, the old way).

The hormone is NOT the same, therefore the test is not the same.

Alternatively, the horse test cannot detect pregnancy in humans accurately, either.

Answer 2

I would think that the hormones between different species would be different enough to make the test inaccurate. Even if the pregnancy hormone was the same in all species, there are still other hormones floating around that could throw it off, as well as having different levels of the hormones.

Answer 3

I would assume it does, pertaining that horses are mammals, just like us, that contain the same hormone. So, a horse should have the same pregnancy hormone HcG or something like that.

Answer 4

This is an interesting question. Although I am not sure if it is or not, I know that you have to call out a vet to check your horse for pregnancy. So, I would assume not, since calling a vet is the mandatory thing to do, but I am not sure. I'd ask a vet.

Answer 5

I'm not sure about horses, but I know that you can use a human pregnancy test for pigs, because our Agri teacher used to use those on the show pigs.

Answer 6

The problem is the horse wouldn't let you use it. They would probably end up kicking you but yeah it would work.
