Ca (Calcium)

LABOKLIN Service ID: 26


  • More than 99% of the body´s calcium is stored in the bones. Calcium is, for example, involved in the transmission of nerve impulses, in muscle contractions and blood clotting.
  • Hypercalcaemia occurs in hyperparathyroidism, but also due to tumours (malignant lymphoma, carcinoma) (see also Parathormone-rp).
  • Nutritive hypercalcaemia in small mammals is partly due to vitamin D3-independent intestinal absorption.
  • Hypocalcaemia is often the cause of parturient paresis in cattle and of an increased tendency for seizure disorders in small animals.

Material

serum or heparin plasma 0.5 ml

Method

photometry

Duration

1 day

Remark

  • Calcium measurement from EDTA plasma is not possible.
  • In case of concurrent hypoalbuminaemia, the calcium level should be corrected.
    Calculation: Corrected calcium level (mg/dl) = serum calcium level (mg/dl) – (0.4 x serum protein (mg/dl)) + 3.3
