ALB and hypothyroidism: Additionally, median [Chol]s was significantly higher in dogs with more severe hypothyroidism when defined as a lower [TT4]s < 0.47 μg/dL vs. ≥ 0.47 μg/dL (i.e., < 6 nmol/L vs. ≥ 6 nmol/L), and in HAC dogs with [ALP]s activity ≥ 1,000 U/L vs. < 1,000 U/L, but significantly lower in HA dogs with [Alb]s < 28 g/L vs. ≥ 28 g/L.
