Independent Evaluations of COVID-19 Serological Tests

Serology tests detect the presence of antibodies in the blood when the body is responding to a specific infection, like COVID-19. In other words, the tests detect the body’s immune response to the infection caused by the virus rather than detecting the virus itself. In the early days of an infection when the body’s immune response is still building, antibodies may not be detected. This limits the test’s effectiveness for diagnosing COVID-19, and this is one reason serology tests should not be used as the sole basis to diagnose COVID-19. Serology tests could play a role in the fight against COVID-19 by helping healthcare professionals identify individuals who may have developed an immune response to SARS-CoV-2. In addition, these test results can aid in determining who may donate a part of their blood called convalescent plasma, which may serve as a possible treatment for those who are seriously ill from COVID-19. However, to use serology tests properly, it is important to understand their performance characteristics and limitations. Moreover, studies are underway to address questions that will better inform the appropriate use of these tests, such as whether the presence of antibodies conveys a level of immunity that would prevent or reduce the severity of re-infection as well as the duration for which immunity lasts.

About this testing program

Introduction

The serology tests were tested at the Frederick National Laboratory for Cancer Research (FNLCR), a Federally Funded Research and Development Center (FFRDC) sponsored by the National Cancer Institute (NCI) or by the Hemostasis Laboratory Branch, Division of Blood Disorders, National Center on Birth Defects and Developmental Disabilities, Centers for Disease Control and Prevention (CDC).

Panel Composition

Each test was evaluated against “Panel 1”, “Panel 2”, “Panel 3”, or “Panel 4”, each of which include frozen SARS-CoV-2 antibody-positive serum samples (\(n=30\)) and frozen antibody-negative serum and Anticoagulant Citrate Dextrose Solution Formula A (ACD-A) plasma samples (\(n=80\)). While ACD-A plasma may not be commonly used in clinical practice for serological testing, ACD-A plasma samples were used here because these pre-pandemic samples were most easily acquired from blood banks. The panel size and composition were chosen to enable a laboratory-based evaluation and to provide reasonable estimates and confidence intervals for test performance in the context of limited sample availability. The sample size is comparable to that of a typical sample size used to support Emergency Use Authorization (EUA) by FDA for tests of this type.

Positive samples

Positive samples used were from patients previously confirmed to have SARS-CoV-2 infection with a nucleic acid amplification test (NAAT). Time between symptom onset, NAAT testing, and sample collection is not known for all samples. Both SARS-CoV-2 IgM and IgG antibodies are present in all positive samples used. The Centers for Disease Control and Prevention (CDC) detected the presence of IgG and IgM antibodies at their laboratory using their SARS-CoV-2 spike enzyme-linked immunosorbent assay (ELISA) tests. (See Serology Testing for COVID-19, which notes “CDC’s serologic test has been designed and validated for surveillance and research purposes. It is designed to estimate the percentage of the U.S. population previously infected with the virus – information needed to guide the response to the pandemic and protect the public’s health. The CDC test is not currently designed to test individuals who want to know if they have been previously infected with SARS-CoV-2. Commercial tests are available to provide test results to individuals.”) The presence of antibodies was confirmed at FNLCR using CDC’s developed ELISAs (Pan-Ig, IgG, and IgM) as well as an IgG Receptor Binding Domain (RBD) ELISA developed by the Krammer Laboratory at the Icahn School of Medicine at Mount Sinai. (An implementation of this test, the COVID-19 ELISA IgG Antibody Test, has been granted an EUA authorization by FDA for use at the Mount Sinai Laboratory (MSL), Center for Clinical Laboratories, a division of the Department of Pathology, Molecular, and Cell-Based Medicine, New York, NY. See this EUA Summary.) The positive samples selected may not reflect the distribution of antibody levels in patient populations that would be evaluated by such a test. Because all samples are positive for both IgM and IgG, this evaluation cannot verify that tests intended to detect IgM and IgG antibodies separately detect these antibodies independently.

Positive samples were assessed at dilutions of 1:100, 1:400, 1:1600, and 1:6400 by CDC on their Pan-Ig assay, their IgM assay, and their IgG assay. Some samples were run at additional dilutions. Any samples that were positive at a dilution greater than 1:6400 were assigned a titer of 6400 because 1:6400 was the highest dilution at which all positive samples were assessed. Two of these samples, C0107 and C0176, were positive for IgG antibodies at a dilution of 1:25600.

Negative Samples

All negative samples used were collected prior to 2020, before the SARS-CoV-2 virus is known to have circulated in the United States. Negative sample groups include:

  • “Negatives” (n=70): selected without regard for clinical status. This group includes a sample, C0063, that showed reactivity in the Pan-Ig CDC spike ELISA at FNLCR. It includes another sample, C0087, that showed reactivity in the IgG RBD ELISA at FNLCR.

  • “HIV+” (n=10): selected from banked plasma from HIV+ patients. (HIV+ samples were deemed appropriate for inclusion in the panel: (1) to increase the sample size and reduce the confidence interval; and (2) to identify any possibility of cross-reactivity with HIV+ samples. It is anticipated that other types of samples, as they become available, may also be evaluated in any future analyses.) This group includes 3 samples, C0018, C0155, and C0182, that showed reactivity in the IgG RBD ELISA at FNLCR.

All negative samples were assessed at dilutions of 1:100 and 1:400 by CDC on their Pan-Ig assay. A subset of samples was assessed in parallel at additional dilutions and on the CDC IgM and IgG assays. All negative samples were negative at a dilution of 1:100 on the CDC Pan-Ig assay. These samples were assigned an undetectable titer (represented as zero (0) in the line data) for the Pan-Ig assay, the IgM assay, and the IgG assay.

Analysis

Samples used in this evaluation were not randomly selected, and sensitivity (PPA) and specificity (NPA) estimates shown may not be indicative of the real-world performance of these tests. Sensitivity and specificity were calculated for each antibody (e.g., IgM, IgG, IgA, and Pan Ig, as applicable) separately. In addition, for tests that measure multiple antibodies separately, sensitivity and specificity were estimated in a combined manner, where a positive result for any antibody a test is intended to detect was considered as a positive test result and a negative result meant that a sample tested negative for all antibodies a test is intended to detect. Positive and negative predictive values were calculated for combined sensitivity and specificity for tests that measure multiple antibodies separately and assuming a prevalence of 5%. Cross-reactivity with HIV+ was evaluated, and results are presented separately in the individual test reports. If cross-reactivity was detected, the samples with HIV+ were not included in calculations of specificity.

In this report, device outputs indicating equivocal results, including outputs such as “borderline” or similar, are referred to as “equivocal.” For ELISA tests that provide equivocal results, for sensitivity and specificity calculations, equivocal results on positive samples were counted as false negative results, and equivocal results on negative samples were counted as false positive results.

Confidence intervals for sensitivity and specificity were calculated per a score method described in CLSI EP12-A2 (2008). (CLSI. User Protocol for Evaluation of Qualitative Test Performance; Approved Guideline—Second Edition. CLSI document EP12-A2. Wayne, PA: Clinical and Laboratory Standards Institute; 2008. See Recognized Consensus Standards.) Confidence intervals for PPV and NPV were calculated using the values from the 95% confidence intervals for sensitivity and specificity. For evaluation of cross-reactivity with HIV+, it was evaluated whether an increased false positive rate among antibody negative samples with HIV was statistically higher than the false positive rate among antibody negative samples without HIV (for this, a confidence interval for the difference in false positive rates was calculated per a score method described by Altman. (Statistics with Confidence: Confidence Intervals and Statistical Guidelines. (2013). Wiley.))

Important caveats

Sensitivity and specificity estimates shown may not be indicative of the real world performance of the tests.

These results are based on serum and plasma samples only and may not be indicative of performance with other sample types, such as whole blood, including finger stick blood.

The number of samples in the panel is a minimally viable sample size that still provides reasonable estimates and confidence intervals for test performance, and the samples used may not be representative of the antibody profile observed in patient populations.

Summary test results

Where the Marketing Status below is shown as “EUA Authorized,” FDA has reviewed data generated by the developer and the independent evaluation and determined, among other things, that based on the totality of the evidence available, that the test may be effective in identifying the presence of antibodies to SARS-CoV-2 as described in the Letters of Authorization for each test, and that the known and potential benefits of the test when so used outweigh the known and potential risks. Such tests are authorized by FDA under Emergency Use Authorizations (EUA) and may be distributed and used as set forth in the EUA. Where the Marketing Status below is shown as “Should not be distributed - Voluntarily withdrawn,” the manufacturers have voluntarily stopped distribution and requested FDA to remove their test from the list of commercial manufacturers distributing serology test kits under the policy outlined in Section IV.D of the Policy for Coronavirus Disease-2019 Tests. Where the Marketing Status below is shown as “Should not be distributed - Removed,” either an EUA request has not been submitted within a reasonable period of time as outlined in the Policy for Coronavirus Disease-2019 Tests or FDA has determined not to issue an EUA for the test. Where the Marketing Status below is shown as “Should not be distributed –- No notification or EUA authorization”, the test was evaluated prior to any planned distribution in the United States and is not known to have been marketed here.
