Hypercalcaemia Profile

LABOKLIN Service ID: 666


The profile supports a structured, pathophysiologically based investigation of disorders of calcium and phosphate metabolism.

Material

Serum 1 ml (centrifuged and separated shortly after coagulation, pipetted off)

  • Please pay attention to the note – country-specific! – on the submission form regarding the temperature during storage/transport!

Parameter

Parathormone (PTH), vitamin D (25OH), calcium, phosphate
The determination of PTHrP concentration is currently included in the profile for canine samples only.

Duration

1–5 working days

Remark

  • The PTH concentration should be assessed in relation to calcium/ionised Calcium (+ phosphate if applicable).
  • In cases of hypercalcaemia, a PTH concentration that is within or exceeds the reference range should be considered inadequately elevated. Secondary renal hyperparathyroidism should be ruled out.
  • Parathormone (rP) supports the identification of paraneoplastic hypercalcaemia (e.g. lymphoma, anal sac carcinoma in dogs).
  • Phosphate and vitamin D (25OH) are used to differentiate between secondary renal hyperparathyroidism and vitamin D-induced hypercalcaemia.
  • In cats, idiopathic hypercalcaemia is the most common form; it is less common as a secondary consequence of chronic kidney disease (CKD).
  • The Hypercalcaemia Profile and Calcium Ionized can be requested together via test number 667. In this case, a serum or heparin plasma tube collected under air exclusion is also to be sent.
