The customer reported a false negative result from a kitted nasal swab of both nostrils with the binax now covid-19 ag card assay performed on (b)(6) 2020.This report was a second false negative result received for a patient that was tested twice with the binaxnow covid-19 ag card.The customer indicated that confirmation testing with pcr was conducted ((b)(6) 2020) and generated positive results.The customer also reported using the bd veritor¿ system for rapid detection of sars-cov-2 that generated a positive result.The customer reported that the patient was asymptomatic, self-quarantining and not on any treatment.The customer confirmed there was no death or serious injury and treatment was not impacted/delayed.Per binax now covid-19 ag card product insert intended use: negative results from patients with symptom onset beyond seven days should be treated as presumptive and confirmation with a molecular assay, if necessary, for patient management, may be performed.Negative results do not rule out sars-cov-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions.Negative results should be considered in the context of a patient's recent exposures, history and the presence of clinical signs and symptoms consistent with covid-19.Per binax now covid-19 ag card product insert precautions and limitations: inadequate or inappropriate sample collection, storage, and transport may yield false test results.False negative results can occur if the sample swab is not rotated (twirled) prior to closing the card.False results may occur if specimens are tested past 1 hour of collection.Specimens should be tested as quickly as possible after specimen collection.False negative results may occur if inadequate extraction buffer is used (e.G.,<6 drops).False negative results may occur if swabs are stored in their paper sheath after specimen collection.The presence of mupirocin may interfere with the binaxnow covid-19 ag test and may cause false negative results.Due to the risk of false negative results potentially leading to no or delayed treatment, this event shall be reported.
