I've forwarded the case study and Cornell pricing info onto my vet. He was not aware of the new "Leptin" test at Cornell. He thanked me for the information. I will be testing Lad's glucose, insulin and leptin levels next month and will let the group know how we make out.
This is my understanding of how the leptin testing can help us:
It removes the potential for false low glucose
Leptin elevation correlates with insulin level
If insulin is in the normal range; leptin will likely still be elevated which is a good way to determine if Lad is still IR.
Helps control appetite and energy.
Please correct me if I'm wrong with the following statements.
Thank you, Dr. Kellon

Absolutely right, except that leptin's normal role of controlling appetite does not work in IR horses because they are leptin resistant.

Hi Jane,
I'm going to be doing my first testing on my horse & all this is new to me & my vet.
Is there a link that I can print out for my vet?
Thank you,

Thank you lorna,
but that is 101 pgs. I was hoping for something simpler that I could
send to my vet in the mail since that is his preference.
