    I've heard this test can detect pregnancy much earlier than a scan. Anyone tried it?

    It detects the hormone relaxin which is produced when the embryos implant. It can be done from 14 days ish, but its very unlikely that enough hormone will be produced at this time for it to be detected. In most cases, the hormone isn't detected until after 25 days. In small litters, often the hormone isn't found at all in a blood test.
    Its not a test I personally recommend. Obviously there are no side effects (more than any other blood drawing test) so you only lose money, but for me, I'd rather wait 3 more days for a scan.

    Not particularly. Its only something I have done/ recommended once and that was for a bitch who showed empty on a scan, but I was convinced she was in whelp. She was done around 36 days ish, came back positive, went on to whelp 2 puppies. (Giant breed so easily missed on a scan- especially as she was a fidget bum)

    Is there anything that can detect pregnancy early?

    No, nothing I have heard of. Puppies can sometimes be seen at 21 days by scan, if the scanner is particularly good.

    There aren't any sheep scanners near me. :( I'm supposed to be flying back on 11th April but Eve would only be 3 weeks (if the slip mating worked) then. My friend (who lives in our house) can take her to the vet at 5 weeks I suppose. I don't usually scan but being so unsure this time I think I will.

    Skye had the relaxin blood test at day 22 of her pregnancy and it confirmed she was pregnant, I was told if it was positive she was definately pregnant, but if it was negative it didn't mean she wasn't pregnant.

    Does any vet do it or do you need a specialist vet? How much does it cost? How long does it take to get the result?

    It's in a test kit that any vet can get (like the test for parvo etc). I work at a vets, so get a discount, can't even remember how much I paid! It doesn't take long to get the result, the vet just takes some blood, spins it down (a couple of mins), then puts the serum on the test with the reagent and then you have to wait 10 mins (I was like an expectant father during this time). I've still got the test with the 2 red lines (1 is a control, the other is the positive result) that means she was pregnant.

    Cheers. Do they have to order it in or will most vets have it?

    I think it depends on the vets, it's best to phone and check.
