Limitations
In patients receiving therapy with high biotin doses (ie, >5 mg/day), no sample should be taken until at least eight hours after the last biotin administration.3 As with all tests containing monoclonal mouse antibodies, erroneous findings may be obtained from samples taken from patients who have been treated with monoclonal mouse antibodies or who have received them for diagnostic purposes.3 In rare cases, interference due to extremely high titers of antibodies to streptavidin and ruthenium can occur.3 The test contains additives that minimize these effects.
