Witness Relaxin Pregnancy Test Kit 5ctThis is a fabulous kit that does require a BLOOD sample. You can draw it yourself or have it drawn at your Vet, SPIN IT DOWN to get the plasma (the clear liquid at the top) and the two drops that the Relaxin kit requires. It is simple and easy to use if you have the ability to draw your own blood and a centrifuge at home (get one on Ebay cheap!). Your Vet should draw and spin down the blood for you for very little money. The kit has FIVE tests included, and the price is about the same as ONE test at the Vet. Be sure the blood is put in an EDTA or heparnized tube, then separated if your Vet does it for you. He will just put the plasma in a new tube and for $10.00 for the blood draw, you can do the rest of the test yourself.

This review is from: Witness Relaxin Pregnancy Test Kit 5ct (Misc.)

I researched this product and it's reviews before purchase. I initial used this test on my bulldog at 25 days from last breeding with a negative result. I waited a week(as manufacture recommends) and re-tested with still a negative result. By the 35th day from breeding she was beginning to show signs of pregnancy and after an ultra-sound was confirmed pregnant (by visual and heartbeats). All three tests was preformed by my vet at $15.00 per blood drawl/spin and $35.00 for the ultra-sound.

What you should know before purchasing/using this test:
The amount of relaxin (serum relaxin level) being produced at the time of the tests depends on the breed, the size of the breed, the size of the litter, LH(luteinizing hormone) surge and when the test is preformed.

For example: If the litter is small there may not be enough relaxin being produced to react with the test. The same would be true if it is a small breed or preformed to early.

I now believe the best option for my female bulldogs in the future will be an ultra-sound as recommended by my vet.

One note pre review: you have to know how to do a blood draw and spin it down to make serum for this test. If you can't do that - go to your vet!!!

Very clear instructions - No false positives with this test - Very easy to use. 2 drops serum in clearly marked well/2 drops buffer solution. Results in 10 mins. Kit contains 5 test so if you wont need that many you can either share with a breeder or, just go to your vet. For those of us with the ability to do blood draws and can use the test in a year or so - a very very good product with accurate results and a money saver. Recommend !
