PPID Testing :/

I think I need the support to make the call... I lost my heart first & horse a year ago on the 19th of May unexpectedly, then my dog due to a brain tumor on the 11th of January (which progressed so quickly she passed away just 2 weeks after showing symptoms on the day she saw the neurologist), and now I think my 26 year old gelding may have PPID and I'm stressin'.

My vet said he looks to be showing early signs of it during their spring shots in March, but didn't mention the idea of testing...
