| Hi, I am doing a pre-purchase on a mare (out of state). I am concerned about pssm2 after a terrible experience living with one. This mare has not tied up, but I do think there have been some minor warning signs disclosed. Probably not anything anyone else would tune in to, but after my experience I am sensitive. It would be a deal breaker for me as I do not ride/work horses 7 days a week.
Muscle biopsies are kind of a big deal. As a seller are you going to agree to a 1/2 inch cube biopsy on a horse that may or may not sell?
This seller is very nice, but sheesh...it's a lot to ask!! I didn't realize it was so invasive. |

| There's a hair follicle test out there, search for cheeka77 or shoot her a message and she can tell you about it.

| I understand your concern as I too have a PSSM horse, but as a seller I would not agree to that. A muscle biopsy is invasive and requires stall rest to recover and heal from. If you are having feelings that this horse may have PSSM, then I would walk away.
The hair test and blood test only test for type 1. Type 2 is only found through a muscle biopsy. I have heard rumors that there is also now a type 3, but I don't know how that is tested for.

| Thanks everyone!! I have read about and will consider the hair sample test, but my vet said muscle biopsy is the only true determination.
I have always said I would not buy another without confirmation of negative pssm2, but I guess that is not a pre-purchase option. |

| I have a pssm type 2 horse myself. And, I can tell you that even though I've been through a long process with figuring mine out and understand what it entails to maintain one, I wouldn't be willing to have a muscle biopsy done on a horse I'm selling either.
The blood test they have for type2 through Equisec isn't considered the standard testing protocol but, hopefully that or something other than a muscle biopsy will be made available soon.

Location: Southeast Louisiana | I wouldn't do that test on a horse I was selling. As a seller, I would agree to hold the buyer's money if they are going to have the test done right away. After they pay me for the horse. I would take the horse back if it turned out to have pssm. |

This is not quite correct - to test for the "blanket PSSM2", yes it takes a muscle biopsy. BUT there are hair folicle tests now that test for genes that make up PSSM. There is no PSSM3 - but there is P2, P3, P4 so far - the GENES that make up the PSSM2 disease. |

| With the new test through EquiSeq I would go that route and it will be a lot cheaper ($125). As someone with a P2 horse, there are definitely symptoms the general public doesn't know about/understand that "we" do, so they say the horse has never tied up but what about the other things? Are you on the PSSM forum on FB? As a seller, I guess if you were a serious buyer who put down a deposit, signed a contract, and paid the entire vet bill and afterare I would allow it but it is so much easier to pull hair and get it tested now. :) |

| I have three pssm2 horses, one n/p2, one P2/P2, and one n/P3 and yes all have been symptomatic. As I seller I would not allow anyone to biopsy my horse, however I would be okay with the hair test. Keep in mind though just having only one of the variants tested is not going to tell you if your horse has pssm or not. I keep seeing stallion owners posting on the pssm group that their horse is P2 n/n soo yaayy its pssm2 clear... not true, it could still have another variant. There is a P2 and P3 test currently offered. And then the P4 test is currently not available for purchase but sounds like it will be soon. Equiseq had been offering Px (rer) and P4 tests for free if you did both the P2 and P3 tests.
I will not purchase another horse without doing the tests first. Only one of my pssm2 horses is rideable.

| Thanks everyone! I am going to pass on the horse. I am a serious buyer and the seller is awesome, but I just agree that it is too much to ask. Someone that knows the mare said she sweats much more than average and gets (visually) tight muscled before a run. That is the only red flag, but I can't take a chance.
I'm disappointed, both by missing out on this mare and by not having an easier way to pre-purchase check for this very debilitating condition! |

Equiseq has a hair/blood test available now for P2, P3, P4, and Px
Turnaround time is 2-6 weeks according to the FB group.

| I just had one done recently from equiseq, got the results 2 days ago. It took 3 1/2 weeks from the time it was received at their office.
The first couple took months and months, they were submitted when the testing first was offered. |

Why don't you go observe the mare at a race and see for yourself. Especially if you really liek her. I have 2 like that and Neither are PSSM horses.
The PSSM horse I have shows no signs until after a run 1 out of 20 times.

There is a hair test for type 2 and the other variants. It is very new though.
www.EquiSeq.com is the webstie for the lab that does them. |

Do the hair test through EquiSeq - a muscle biopsy will only give you a positive result if it is taken during an "episode". The hair test will be far less invasive and will provide you with a difinitive answer. |

| I actually flew out twice and rode my gelding that is pssm before I bought him. He was fine both times I flew out there to ride and watch. After he got very symptomatic I heard from several people that he had tied up beforehand.
I have now had another person that knows this horse tell me to pass. I'm so glad I took the time to follow my gut!
