 Behind the false negative of new crown pneumonia: sampling, environment and sensitivity can influence


New crown pneumonia false negative: clinician sampling kit sensitivity and other factors related (source: original)

On February 8, a case of Three Yin caused concern. The new coronavirus nucleic acid of three throat swabs of febrile pneumonia patients was negative. But A-flow nucleic acid was positive. After admission, the patient was intubated into the ventilator, and was positive only through the alveolar lavage test, so as to make a definite diagnosis. Doctors say there are many factors that cause false negatives. For example, sampling by clinician, sensitivity of reagent box, clean environment of laboratory, etc. In addition, more attention should be paid to the judgment and management of discharged patients.
