Intended Use
The VITROS Immunodiagnostic Products Anti-SARS-CoV-2 IgG Reagent Pack when used in combination with the VITROS Immunodiagnostic Products Anti-SARS-CoV-2 IgG Calibrator is a chemiluminescent immunoassay test intended for the qualitative detection of IgG antibodies to SARS-CoV-2 in human serum. The VITROS Anti-SARS-CoV2 IgG test is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. At this time, it is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity. The VITROS Anti-SARS-CoV-2 IgG test should not be used to diagnose acute SARS-CoV-2 infection. Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, that meet requirements to perform moderate or high complexity tests.
Results are for the detection of SARS-CoV-2 antibodies. IgG antibodies to SARS-CoV-2 are generally detectable in blood several days after initial infection, although the duration of time antibodies are present post-infection is not well characterized. Individuals may have detectable virus present for several weeks following seroconversion.
Laboratories within the United States and its territories are required to report all results to the appropriate public health authorities.
The sensitivity of VITROS Anti-SARS-CoV-2 IgG test in early infection is unknown. Negative results do not preclude acute SARS-CoV-2 infection. If acute infection is suspected, direct testing for SARS-CoV-2 is necessary.
False positive results for VITROS Anti-SARS-CoV-2 IgG test may occur due to cross-reactivity from pre-existing antibodies or other possible causes.
Samples should only be tested from individuals that are 15 days or more post-symptom onset
The VITROS Anti-SARS-CoV-2 IgG test is only for use under the Food and Drug Administration's Emergency Use Authorization.
Summary and Explanation of the Test
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a beta coronavirus that causes the Coronavirus Disease 2019 (COVID-19) and pandemic. SARS-CoV-2 is mainly transmitted through droplets and contact routes, and the virus infects human cells via binding to angiotensin converting enzyme 2 (ACE2). 1- 2 People who are infected with SARS- CoV-2 may express signs and symptoms of acute respiratory illness, such as fever, cough, shortness of breath, but can also be asymptomatic. Symptomatic, pre-symptomatic and asymptomatic SARS-CoV-2 carriers all can be potential sources for viral transmission. 3 Currently, no specific treatments or vaccines are available for COVID-19.
Real-time reverse transcription polymerase chain reaction (rRT-PCR) detecting viral genes is the current gold standard for the diagnosis of COVID-19. Upper respiratory specimen, such as nasopharyngeal swab and oropharyngeal swab, are commonly used for diagnostic testing. 2
Principles of the Procedure
The VITROS Immunodiagnostic Products Anti-SARS-CoV-2 IgG test is performed using the VITROS Anti-SARS-CoV-2 IgG Reagent Pack and the VITROS Anti-SARS-CoV-2 IgG Calibrator on the VITROS ECi/ECiQ/3600 Immunodiagnostic Systems and the VITROS 5600/XT 7600 Integrated Systems. An immunometric technique is used; this involves a two stage reaction. In the first stage antibodies to SARS-CoV-2 present in the sample bind with SARS-CoV-2 spike protein coated on wells. Unbound sample is removed by washing. In the second stage horseradish peroxidase (HRP)-labeled murine monoclonal anti-human IgG antibodies are added in the conjugate reagent. The conjugate binds specifically to the antibody portion of the antigen-antibody complex. If complexes are not present, the unbound conjugate is removed by the subsequent wash step.

INSTRUCTIONS FOR USE
Warnings and Precautions
The bound HRP conjugate is measured by a luminescent reaction 4. A reagent containing luminogenic substrates (a luminol derivative and a peracid salt) and an electron transfer agent is added to the wells. The HRP in the bound conjugate catalyzes the oxidation of the luminol derivative, producing light. The electron transfer agent (a substituted acetanilide) increases the level of light produced and prolongs its emission. The light signals are read by the system. The amount of HRP conjugate bound is indicative of the amount of SARS-CoV-2 IgG antibody present.

Calibration
Calibration Procedure
· Calibration is lot specific; reagent packs and calibrator are linked by lot number. Reagent packs from the same lot may use the same calibration.
· A Master Calibration is established for each new reagent lot by performing multiple tests. This is the process by which a lot-specific parameter [a] which links the signal at the cutoff (cutoff value) to the calibrator signal is determined.
· Cutoff value = (a x Signal of Cal 1)
· Ensure that the Master Calibration for each new reagent lot is available on your system. · Process calibrator in the same manner as samples. Load sufficient for the automatic duplicate determination.
Calibration need not be programmed if bar code labels are used; calibration will be initiated automatically. · When the calibrator is processed, the validity of the calibration is assessed against quality parameters which
compare the actual signal of the calibrator with the expected signal. If the calibration is acceptable the cutoff value is calculated and stored for use with any reagent pack of that lot. · The quality of calibration cannot be completely described by a single parameter. The calibration report should be used in conjunction with acceptable control values to determine the validity of the calibration.
· Recalibration is required after a pre-determined calibration interval, or when a different reagent lot is loaded. · Calibration results are assessed against a range of quality parameters. Failure to meet any of the defined quality
parameter ranges will be coded in the calibration report. For actions to be taken following a failed calibration refer to the operating instructions for your system.
· Refer to the operating instructions for your system for detailed instructions on the calibration process.
When to Calibrate
· Calibrate when the reagent pack and calibrator lot changes.
· Calibrate every 28 days.
· After specified service procedures have been performed. · If quality control results are consistently outside of your acceptable range.
For additional information on when to calibrate, refer to the operating instructions for your system.
Traceability of Calibration
Calibration of the VITROS AntiSARS-CoV-2 IgG test is traceable to an in-house reference calibrator which has been value assigned to optimize clinical sensitivity and specificity.

Quality Control
Calibration Model
Results are calculated as a normalized signal, relative to a cutoff value. During the calibration process a lotspecific parameter is used to determine a valid stored cutoff value for the VITROS Immunodiagnostic and VITROS Integrated Systems.
Quality Control
Quality Control Material Selection
VITROS AntiSARS-CoV-2 IgG Controls are recommended for use with the VITROS Immunodiagnostic and VITROS Integrated Systems. There are 2 VITROS AntiSARS-CoV-2 IgG Controls (antiSARS-CoV-2 IgG negative and antiSARS-CoV-2 IgG positive. The performance of other commercial control fluids should be evaluated for
zyxwvu compatibilitywith thistest before theyare used for qualitycontrol.
Control materials may show a difference when compared with other antiSARS-CoV-2 IgG methods if they contain high concentrations of preservatives, stabilizers, or other non-physiological additives, or otherwise depart from a true human sample matrix. Appropriate quality control value ranges must be established for all quality control materials used with the VITROS AntiSARS-CoV-2 IgG test.
Quality Control Procedure Recommendations
· Good laboratory practice requires that controls be processed to verify the performance of the test. · Choose control levels that check the clinically relevant concentrations. · To verify system performance, analyze control materials:
After calibration If the system is turned off for more than 2 hours After reloading reagent packs that have been removed from the MicroWell Supply and stored for later use According to local regulations or at least once each day that the test is being performed After specified service procedures are performed
If quality control procedures within your laboratory require more frequent use of controls, follow those procedures. · Analyze quality control materials in the same manner as patient specimens. · If control results fall outside your acceptable range, investigate the cause before deciding whether to report
patient results. · Refer to published guidelines for general quality control recommendations. 10
For more detailed information, refer to the operating instructions for your system.

Limitations of the Procedure
zyxwvuts KnownInterferences The VITROS AntiSARS-CoV-2 IgG test was evaluated for interference consistent with CLSI document EP7. 11 Commonly encountered substances were tested on two lots of reagents. Of the compounds tested, none was found to interfere with the clinical interpretation of the test. Refer to "Substances that do not Interfere" for a list of compounds tested that did not show interference.
Other Limitations
· Samples should only be tested from individuals that are 15 days or more post-symptom onset. · Heterophilic antibodies in serum samples may cause interference in immunoassays. 12 These antibodies may be
present in blood samples from individuals regularly exposed to animals or who have been treated with animal serum products. Results that are inconsistent with clinical observations indicate the need for additional testing. · A negative result can occur if the quantity of antibodies for the SARS-CoV-2 virus present in the specimen is below the detection limit of the assay, or the virus has undergone minor amino acid mutation(s) in the epitope recognized by the antibody detected by the test. · The results obtained with this test should only be interpreted in conjunction with clinical findings, and the results from other laboratory tests and evaluations.
· This test should not be used for screening of donated blood for the purpose of preventing COVID-19 transmission.
· A positive result may not indicate previous SARS-CoV-2 infection. Consider other information including clinical history
and local disease prevalence, in assessing the need for a second but different serology test to confirm an immune
response.
· The performance of this test has not been established in individuals that have received a COVID-19 vaccine. The
clinical significance of a positive or negative antibody result following COVID-19 vaccination has not been established,
and the result from this test should not be interpreted as an indication or degree of protection from infection after
vaccination. · The performance of this test was established based on the evaluation of a limited number of clinical specimens. The clinical
performance has not been established in all circulating variants but is anticipated to be reflective of the prevalent variants in circulation at the time and location of the clinical evaluation. Performance at the time of testing may vary depending on the variants circulating, including newly emerging strains of SARS-CoV-2 and their prevalence, which change over time
