Hypocalcemia threshold
Web4 jun. 2024 · Hypocalcemia occurs in 15 to 88% of hospitalized adult patients, depending on the measurement method (serum or ionized calcium). The majority of calcium in the body resides in bone, with only 1% of total body stores exchanged with extracellular fluid. WebDairy cows with blood calcium concentrations at or below 8.0 mg/dl (2.0 mmol/l) but not showing clinical signs are considered subclinically hypocalcemic. At this cut-off point, Reinhardt and co-workers in a study with 1,462 dairy cows determined that 50% of mature dairy cows and 25% of first-calf heifers experienced subclinical hypocalcemia.
