  • Title: Case report of unexplained hypocalcaemia in a slightly haemolysed sample.
    Author: Cornes M.
    Journal: Biochem Med (Zagreb); 2017 Jun 15; 27(2):426-429. PubMed ID: 28694734.
    Abstract:
    The case presented highlights a common pre-analytical problem identified in the laboratory that was initially missed. It concerns a young, generally healthy adult patient with no significant medical history and no significant family history. They presented with common flu like symptoms to their primary care clinician who considered this was most likely a viral problem that would pass with time. The clinician, however, did some routine bloods to reassure the patient despite a lack of clinical indication. When the sample was analysed the sample was haemolysed with strikingly low calcium. This led to the patient being called into hospital for urgent repeat investigations, all of which turned out to be within normal ranges. On further investigation the original sample was found to be contaminated. This result would normally have been flagged but was missed due to the complication of haemolysis.
