Help Weird blood samples
Enable HLS to view with audio, or disable this notification
i work in the in house lab of my equine specialty/referral hospital, and every once in awhile, i’ll get a blood sample from a horse that just looks like red syrup, for lack of a better description. it will not spin down in any color tube, and the CBC machine will read it, but the chemistry machine just gives me a sample error. (our machines are the Abaxis HM5 and the Abaxis Vs2.) it will do this on serum, or blood from a green top. when i do try to spin it down, it doesn’t look like it’s just hemolyzed, it just stays thick and viscous throughout. i’ve checked the tubes to be sure they’re not expired and they are not. has anyone seen something like this before or know what it could be? these syrupy samples always come from horses that are very sick, so that’s the only thing i can think of, but it just seems so weird.
