Last reviewed 03/2023
Commonly:
- hyperventilation inducing a transient hypocalcaemia; serum total calcium levels normal
Less commonly:
- alkalosis due to alkali infusion to treat acidosis, salicylate poisoning
- high phosphate:
- rapid tumour lysis - e.g. cytotoxic treatment of leukaemia
- excessive phosphate intake - e.g. phosphate containing enemas, excessive oral phosphate (infant milk feeds), parenteral phosphorous
- high citrate from massive blood transfusion if liver cannot metabolise adequately
- acute pancreatitis
