When you are pregnant, prolactin changes are completely normal. In fact, your prolactin must increase in order to encourage the production of milk in your mammary glands. During pregnancy your hormones are all over the place. In particular, your estrogen levels begin to rise, and this is what stimulates the increase in your prolactin levels.
Hypercalcemia in Cats. Hypercalcemia is characterized by an abnormally high amount of calcium in the blood. A cat is considered hypercalcemic when its total serum calcium level is greater than 10.5 mg/dL.
Elevated calcium level is defined as a level greater than 2.7 mmol/ L, with severe hypercalcemia being greater than 3.4 mmol/L. The most common EKG finding associated with hypercalcemia is shortening of the QT interval. In severe cases Osborn or J waves might be seen or ventricular fibrillation might ensue.
