So my gelding's leptin came back 8.32 ng/mL (norm 1-4). He's the 7yo Saddlebred with inexplicable nervous behavior that has been on gabapentin since April, 2014. He recently came up with two high insulins, the latest being 47 uIU/mL. Initially the thought was that perhaps gabapentin was driving the insulin up but with a leptin like that....yeesh! Has anyone ever seen a leptin that high? Cornell only indicates that >7 ng/ml is "high". You guys have more experience than anyone else I know with leptin, so should I believe a leptin this high or throw it out and re-submit a new sample?
