Molecular tests are generally more accurate and mostly processed in a laboratory, which takes longer; antigen testsor rapid testsare processed pretty much anywhere, including at home, in doctors offices, or in pharmacies. Antibodies are y-shaped proteins that look for and attack bacteria and viruses. Different antibody tests may also be designed to detect different SARS-CoV-2 antibodies in addition to the different levels of antibodies. "Roche is proud to make this highly accurate serology test available in the U.S. to determine if a person has developed antibodies to COVID-19," said Matt Sause, President and CEO of Roche Diagnostics North America. The serological assay, described in the journal Scientific Reports. Across the country, a selection of positive COVID-19 samples are sent to specialized labs, where they are anonymously sequenced to identify variants so that public health officials can monitor COVID-19 trends. The rapid test from Beijing Wantai Biological Pharmacy also performed well, with 97.5% sensitivity and 95.2% specificity, according to the review. Molecular tests are offered at pharmacies, doctors' offices, and designated testing locations, such as health clinics, as well as locations set up by private or state and local public health systems. Abbott does not determine the price of the test to the patient. When infected by a virus like SARS-CoV-2, the cause of COVID-19, the body initially produces antibodies known as IgM (immunoglobulin-M), in an attempt to neutralize the virus.
