Manufacturer Narrative

Siemens has been on site and performed several total service calls on the instrument.The system was decontaminated.Siemens continues to investigate.The limitations section of the instructions for use states: "this assay should not be used to diagnose or exclude acute infection.Results are not intended to be used as the sole basis for patient management decisions.Test results should be interpreted in conjunction with clinical observations, patient history, epidemiological information, and other laboratory findings.A reactive test result does not exclude past or present infection by other coronaviruses, such as sars-cov-1, mers-cov, hku1, 229e, nl63, or oc43." a false positive/reactive result would not be used in isolation and would be correlated with clinical history.Additional laboratory testing would be used to determine specific antibody presence.Although there is no potential for serious injury in this case, an mdr will be reported to the fda as a requirement of the emergency use authorization (eua).
