Weefoal test question.

Since my parents wish not to get an ultrasound to confirm if my mare is 100% pregnant or if it's a false pregnancy, (mostly because the vet said she might not be able to see anything with the ultrasound during the 4-8 month period) I'm going to order a wee foal test for 120-300 days.

Question is, if it is a false pregnancy will it show up positive on the test? I'm not sure if in false pregnancy they create the hormone that the test looks for.

If you haven't read my other thread, vet is leaning toward pregnant and is having us vaccinate her just like she is.

They are not supposed to be effected by false pregnancies.

Thank you. I will be happy to have a 100% answer. My mom bought it saying "I'm going to buy it just so I can video tape you waiting for ger to pee" lmao.

Then get a new vet. Sorry, but if a vet can't find a 4-8 month old fetus with an ultrasound, they have no business using an ultrasound. From about 90 to 120 days, the weight of the fetus will usually drop the uterus and fetus over the pelvic brim and into the abdominal cavity, but while it might be difficult to palpate, it's easily located via ultrasound. And I cannot IMAGINE missing an 8 month fetus by palpation, let alone by ultrasound.

The test is checking for eCG (equine chorionic gonadatropin) which is released by the endometrial cups. Those endometrial cups are formed from the chorionic girdle. In order to have a chorionic girdle you MUST have had a pregnancy. So, if the mare has a false pregnancy and was never bred, there would be no conceptus and consequently no chorionic girdle. No chorionic girdle, no endometrial cups. No endometrial cups, no eCG. No eCG, no false positive with the Wee Foal test. Make sense?

And what is the vet basing his/her hypothesis on? And by that statement, I'm assuming that the mare has been bred. If that's the case, the above information is moot. With that said, you can have a false positive if the mare was bred and lost the pregnancy. Get someone that knows how to palpate/ultrasound. Or, have a blood test for estrone sulfate done.

Good luck!

I have to agree - a vet that can't find a foal at 6 or 8 months is not much of a horse vet...

Yes, Avalon that all made sense. There is a high possibility she was bred. I bought her in April as a rescue. She had been with a stallion since being taken from her owner for neglect in December.

Flashback. Vet came out a week into April, about a week after we bought her. Did an ultrasound and seen nothing but the cervix was tight.

If I'm not going tonget a false positive then I think im going to do the wee foal.

When the vet checked yesterday her cervix was still tight (four months later) and her uterus had dropped below the pelvic brim.

She isn't a equine vet, mixes. I think more small animals because when I took my other mare up tontheir office they had NO place for a trailer and NO place to keep a horse.

Our other only equine vet looked at my other mare! Just with his eyes, to see if she was pregnant. Said no and made me pay 90 dollars. I went to the vet I have now and found that same mare had a uterine infection.

As a former breeder, I highly recommend a well qualified equine vet if a person is breeding. It is prudent, pays dividends in the long run, and is well worth the investment.

That's not meant to be critical, it's just my recommendation that I would make to anyone, although I realize in this case your parents are calling the shots...

Yes, my parents are calling the shots. I even tried for them to allow another ultrasound at 8 months, but no go.

I tried a bloodtest, and they said no. If I had the money, I would be doing it but seem how they are paying for it, I have to go with what they say. I'm lucky enough I talked them into a weefoal test, but I guess they aren't the ones that have to wait for a horse to pee.

Though, thankfully they will be getting her vaccinated September, November, and January for Pneumabort, and all her vaccinations in February I believe for antibodies. But, if the weefoal turns out negative is it safe to assume she is having a false pregnancy?

I used a weefoal with my Haflinger mare last year. What I did was exercise her for about 30 minutes and put her right into the stall. She went straight in and peed. I used a bucket to catch it with, a clean one. Good luck : )
