I am sorry if this has been posted - honestly I did not read all 5 pages.

What is a normal T-4 count for a healthy skinny?

Thanks

Hyperthyroidism is now officially recognized in guinea pigs.

The latest edition of Diseases and Disorders - Small Mammals: guinea pigs. Page 260, 261 (sorry, all I have to go on is the photocopied sheets my vets gave me from the newest med book she got).

This means nothing to me but the vet techs out there will be able to make sense of it:

Serum thyroxine(T) - tiny 4 is at the bottom right of the "T"-measurement reference range, 1.1-5.2 ug/dL(14.? - crease in the page can't see if there is a number following 14 - it's probably 14.15 - 66.9 nmol/L)

That is encouraging. It certainly exists.

Got an email into the vet clinic for the name of the book.

- prevalence of thyroid pathology in guinea pigs in one study was 4.6%

Of course we don't know what that means unless we have the data of the guinea pigs in the study.

Pigs of all ages can be affected but more common in pigs older than 3 years. Doesn't appear in one sex more than the other.

Gah, not cheap. Erg. It's on the way, though, so when it gets here I'll look at the creased page.

Dr. Mayer is at UGA (University of Georgia). He did the rodent section in Carpenter's 4e.

About time! My vets have all been flying by the seat of their pants using cat norms and protocols.

Page 260 in the reference Pinta mentions:

• Serum thyroxine (T4) measurement: reference range, 1.1-5.2 μg/dL (14.2-66.9 nmol/L)

1.1 to 5.2 is a big range of "normal" (same thing that happens in humans for this hormone).

OT: this is a pretty good book and valuable reference overall, but they do discount the use of prokinetics (motility agents) in a number of diseases and disorders, including bloat/stasis. I have a very serious problem with that, since metoclopramide has been of great benefit to several of our pigs, and cisapride has been helpful to many on this board.

I can add this value to the norms page if you give me all the details I need to quote the source:

(too bad they discount motility agents!)

Will do. I'll bring the book back in later this week.

They have a section on echocardiogram norms too -- want that?

Sure! I think so long as source is cited, we can add modest amounts of info.

The echocardiogram norms would be great for the heart story page.

The echo norms are in the form of a table. Lynx, should I copy and mail this to you? It'd be safer than me trying to retype it.

The book is Clinical Veterinary Advisor, Birds and Exotic Pets, by Jörg Mayer and Thomas M. Donnelly (publisher Elsevier Saunders -- 2013)

That would be great, Talishan (copy and mail).

Alternatively, can I scan it and if it comes out readable, email it to you?

That might work!

Do watch the size though. I think 100dpi is readable. If it gets to big I will have trouble accepting it (i.e. if only one page, should be fine).
