SARS-CoV-2 Serological Test Results from Multiple Assay Platforms

Data.cdc.gov hosts a dataset comparing the performance of multiple serological tests for detecting SARS-CoV-2 antibodies. The evaluation includes one in-house ELISA, two commercial chemiluminescence assays, and a surrogate virus neutralization test, using a panel of PCR-confirmed patient sera. The dataset was last updated on February 23, 2025.

Use Cases

• Compare assay reactivity outcomes using Abbott Reactivity, Ortho Reactivity, and In-House CDC ELISA Reactivity columns.
• Analyze correlations between neutralization titers and surrogate test results using mNT TITER and sVNT % Inhibition columns.
• Assess quantitative signal values across platforms using Abbott S/C Values, Ortho Index Values, and In-House CDC ELISA S/T Values columns.
• Model diagnostic accuracy by stratifying results based on the PCR confirmed status of serum samples.

Strengths

• Directly compares results from four distinct serological assay platforms.
• Includes log10-transformed values for several key metrics, facilitating statistical analysis.
• Reference standard includes PCR-confirmed COVID-19 patient sera and a negative control group.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
