Has anyone used the Witness LH surge test kit ? Was it accurate ?

We use it every time we breed and love it. We know at 25-28 days whether or not our girl is pregnant and it's been very accurate. When we've tried to use it earlier, say on day 21, if the bitch is only carrying one or two pups, you may get a false negative, as I just don't think their hormones are strong enough to make the test show positive at that point.

I think you're thinking of the Relaxin test, not the LH surge test.

I just got that email this morning, too, OP.

Seems like it would be a great test to use if it's accurate.
I've used the Premate test with 100% success. But it requires
mixing and keeping the vials chilled. The witness LH test seem
pretty simple with quick results.
In the area I'm in it takes almost two days for results on a regular
blood draw and sent to the lab. That's just too long to wait, you could
miss the breeding.

I dont understand why you would want to pay twice as much ($229) for half as many test (6 test)

you still have to draw blood and use a centrifuge.
Premate only takes another 20 minutes and I can get 12+ test from one kit.

I didn't know what the price on the witness tests were yet.
Makes Premate much more reasonable.:-)
