T136 |
0-294 |
Sentence |
denotes |
Serologic tests that identify antibodies (such as IgA, IgM, and IgG) to SARS–CoV-2 from clinical specimens (such as blood or saliva), such as enzyme-linked immunosorbent assays, may be less complex than molecular tests and have the potential to be used for diagnosis in certain situations (46). |
T137 |
295-470 |
Sentence |
denotes |
However, their utility for diagnosing acute infections is probably limited around the time of symptom onset, when viral shedding and transmission risk seem to be highest (32). |
T138 |
471-553 |
Sentence |
denotes |
Antibody responses to infection take days to weeks to be reliably detectable (46). |
T139 |
554-670 |
Sentence |
denotes |
Negative results would not exclude SARS–CoV-2 infection, particularly among those with recent exposure to the virus. |
T140 |
671-876 |
Sentence |
denotes |
Cross-reactivity of antibody to non–SARS–CoV-2 coronavirus proteins is also a potential problem, whereby positive results may be the result of past or present infection with other human coronaviruses (47). |
T141 |
877-1089 |
Sentence |
denotes |
Serologic assays might be more relevant in scenarios in which patients present to medical care with late complications of disease, when RT-PCR may be falsely negative, because viral shedding drops over time (48). |
