Enzyme-Linked Immunosorbent Assay

Enzyme-Linked Immunosorbent Assay

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...

Public Health

Background:

The COVID-19 pandemic caused by SARS-CoV-2 has global health and economic impacts.
Antibody testing is considered for phased economic reopening, necessitating accurate diagnostic tools.
Understanding the performance of SARS-CoV-2 antibody tests is vital for infection control.

Purpose of the Study:

To review current antibody testing methods for SARS-CoV-2.
To assess the sensitivity and specificity of available antibody tests.
To identify limitations and gaps in knowledge regarding COVID-19 antibody testing.

Main Methods:

Review of current antibody tests for SARS-CoV-2, including rapid diagnostic tests, EIAs, neutralization assays, and CIAs.
Analysis of sensitivity and specificity data for antibody tests in symptomatic and asymptomatic patients.
Evaluation of potential biases and limitations in existing studies.

Main Results:

SARS-CoV-2 antibody tests detect IgA, IgM, or IgG antibodies.
Specificity is low in the first week post-exposure, increasing in subsequent weeks.
Many tests exhibit high false-negative rates and risks of bias (participant selection, test application, reference standards, timing).

Conclusions:

No standardized antibody test currently exists for SARS-CoV-2.
Limitations in current antibody test data quality and bias risk affect accuracy reporting.
Further research is needed to improve the reliability and standardization of COVID-19 antibody testing.
