Calcium, ionized (includes total serum calcium)
Days test started:
Specimen Type/Volume2 mL serum.
Shipping InformationShip in insulated container with freezer packs.
Collection ProtocolCollect blood into a red-top vacutainer; avoid hemolysis. Separate serum from cells as soon as possible following collection and transfer to a leakproof tube. Freeze immediately. Ship on freezer packs.
Canine ionized calcium reference interval: 1.27-1.45 mmol/L. Feline ionized calcium reference interval: 1.15-1.34 mmol/L. Increases in ionized calcium typically parallel increases in total serum calcium concentrations, except for animals with renal failure in which the increase in total calcium is due to calcium binding with citrate, phosphate, and bicarbonate.
