Diagnostic Indexes of a Rapid IgG/IgM Combined Antibody Test for SARS-CoV-2

Category: Article Summary

Topic: Testing and Treatment

• Several new studies demonstrate that antibody tests have important diagnostic value in addition to RNA tests.  
• Ying et al found an IgG/IgM combined test was easy to use, had adequate sensitivity and specificity, short turnaround time and no specific requirements for additional equipment or skilled technicians. They suggest it could be used for mass testing in combination with RT-PCR testing.
