  • Extra notes in the data
  • Reason
    Siemens healthcare diagnostics has received complaints regarding the coat-a-count direct androstenedione assay demonstrating a higher frequency of results >10 ng/ml (>25 nmol/l) compared to alternate platforms. through internal investigation siemens has determined that there is a potential of cross-reactivity in circulating physiological serum levels up to 8.82% detected with spironolactone and its two metabolites, canrenone and 7a-thiomethyl spironolactone with the ria cac direct androstenedione assay. the degree of cross-reactivity is dependent on the circulating dose in the patients’ serum.
  • Action
    Siemens is advising pathology laboratories that the assay should not be used on patients being treated with spironolactone due to cross reactivity. These patients should be tested using an alternative method. A look back using another test method may be required if a patient has been administered spironolactone.
