    How can enzyme levels in circulation be used to monitor pathology progression?

    <p>The duration of enzyme presence in circulation can indicate whether pathology is likely to be detected or missed, as well as provide insights into the frequency of sampling needed to assess improvement or worsening of the condition.</p> Signup and view all the answers

    What are some possible causes of hypocalcemia in cats?

    <p>Possible causes of hypocalcemia in cats include primary hyperparathyroidism, spontaneous immune-mediated hypocalcemia, e.g. feline hyperthyroidism, periparturient tetany (eclampsia), nutritional deficiency of calcium or Vitamin D (e.g. all meat diets, severe GI disease, sunlight), and pancreatitis with fat necrosis.</p> Signup and view all the answers

    What are some possible causes of hypercalcemia in horses and rabbits?

    <p>Possible causes of hypercalcemia in horses and rabbits include renal failure, which could give rise to genuine hypercalcemia in horses, and egg-laying species generating high total calcium (tCa) due to an increase in protein-bound fraction (ovalbumin) but normal ionized calcium (iCa).</p> Signup and view all the answers

    What are some factors that can affect the interpretation of ALT and ALKP levels in different species?

    <p>Factors that can affect the interpretation of ALT and ALKP levels in different species include the liver specificity of these enzymes, with ALT being almost completely liver-specific in dogs and cats, alternate hepatocellular enzymes (GLDH, SDH) in equidae and ruminants, and the availability of sensitive feline TSH for testing.</p> Signup and view all the answers
