TUESDAY TRIVIA!

Last week we learned about the clinical signs/physical appearance of a horse affected by Equine Metabolic Syndrome [EMS].  Most of the time these findings are enough to make a diagnosis or at least put it at the top of the list.  But what about when we want to absolutely sure or if we're judging if our treatment is working at the level of the hormones involved?  So here is today's question!

What is a test we can perform to confirm that a horse has Equine Metabolic Syndrome?
 (hint: there's more than one correct answer)

Feel free to post your guess here or on our Facebook page.  The answer will be posted at the end of the day, Good Luck!
