The blood work below is from "Grace" Kennedy, an 8 year old FS Yorkie. She has a history of small bowel diarrhea, and is showing no signs attributable to hypocalcemia.
What is the likely cause of her low total calcium?
What is the likely cause of her low total calcium?

Decreased PTH secretion
b)

The blood work below is from "Grace" Kennedy, an 8 year old FS Yorkie. She has a history of small bowel diarrhea, and is showing no signs attributable to hypocalcemia.
Because you are sure enough that the hypoalbuminemia is causing her low total calcium, you would not investigate further, but if you wanted to make sure she wasn't truly hypocalcemic you would measure which of the following?

6.
13 year old MC Dalmatian with a history of PU/PD, no other signs.
IONIZED CALCIUM 1.7 MMOL/l (1.19-1.48)
All other blood work normal
Toast had a normal rectal exam, lymph nodes are normal, and he had a nodule on the right side of his ventral neck, compatible with an enlarged parathyroid gland.
What is his diagnosis?
