BioMedomics CoV-SCAN Rapid Antigen Test demonstrated high sensitivity and specificity for numerous SARS-CoV-2 variants, including Omicron and Delta, in a peer-reviewed point-of-care clinical evaluation

Recently published in the highly regarded, peer-reviewed Journal of Clinical Virology Plus, a clinical point-of-care and laboratory trial, performed in conjunction with the Columbia University Irving Medical School, demonstrated the ability of the BioMedomics CoV-SCAN Rapid Antigen Test to detect SARS-CoV-2 variants with high sensitivity and specificity. These results are due to CoV-SCAN’s unique design, using 4 unique antibodies to detect SARS-CoV-2.

In laboratory testing, CoV-SCAN detected 14 variants, including Omicron and Delta, with similar sensitivity to the wild-type virus; CoV-SCAN did not cross-react with any other human coronaviruses.

In clinical point-of-care (POC) testing on 148 individuals over age 2 with symptom onset of less than or equal to 5 days, CoV-SCAN detected SARS-CoV-2 in 87.2% of COVID-19 infected individuals and did not misdiagnose any non-infected individuals. In another 884 asymptomatic individuals, CoV-SCAN detected 85.7% of COVID-19 infected individuals and correctly diagnosed 99.7% of non-infected individuals.

Importantly, CoV-SCAN detected SARS-CoV-2 in greater than 97.2% of patient specimens with CT values < 30, a well-established clinically meaningful cutoff for infectivity.

These results demonstrate that CoV-SCAN should detect SARS-CoV-2 variants, known and unknown, in almost all individuals harboring infectious quantities of COVID-19. Additionally, CoV-SCAN’s high specificity makes it incredibly useful for the early identification of new infectious clusters before they become hotspots.

BioMedomics COVID-19 IgG/IgM Rapid Test highly effective in point of care (POC) use

The BioMedomics COVID-19 IgG/IgM Rapid Test is a rapid, point-of-care (POC) lateral flow immunoassay (LFA) that detects antibodies to the SARS-CoV-2 spike protein receptor-binding domain (RBD). It detects both early (IgM) and late (IgG) marker antibodies in human finger-prick capillary blood, venous whole blood, serum, and plasma. Since its launch in March 2020, it has gone through several independent validations and is being used globally in hospitals, clinics, and government agencies.

Widespread deployment of POC testing for SARS-CoV-2 could transform the global COVID-19 response, helping individuals quickly understand whether they were previously infected or have developed a robust response to vaccination, and informing health officials on the level of community protection that may be present.

As their use extends beyond traditional clinical settings to help determine serostatus after infection or vaccination, evaluating test performance against laboratory assays at the POC, not just in controlled laboratory settings, is essential.

A recent study provides insight into how SARS-CoV-2 lateral flow assays are likely to perform in POC settings when used by individuals other than laboratory professionals.

When used 1 month after the onset of symptoms, the demonstrated robust sensitivity (90%) and complete specificity (100%) in a heavily exposed household cohort.

CoV-SCAN Antigen Test Kit

CoV-SCAN Rapid Antigen Test

BioMedomics has launched the CoV-SCAN Rapid Antigen Test (CoV-SCAN) to aid in the diagnosis of active coronavirus infection. The test detects the N-protein antigen of SARS-CoV-2 using a novel double antibody sandwich assay format. It uses a panel of antibodies, targeting multiple antigenic sites on SARS-CoV-2 N-protein antigen, that can detect many new variants of concern at equivalent (or up to eight-fold) improved sensitivity compared to original isolate.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a novel beta coronavirus and is the causative agent of Coronavirus Disease 2019 (COVID-19) and the pandemic. SARS-CoV-2 is mainly transmitted through droplets and contact routes, and people who are infected with SARS-CoV-2 may express signs and symptoms of acute respiratory illness, such as fever, cough, shortness of breath, etc., but can also be asymptomatic.

 

In March of 2020, BioMedomics successfully created one of the most reliable, accurate, and fastest COVID-19 antibody tests in the world: the COVID-19 IgM/IgG Rapid Antibody Test. BioMedomics has continued to put their passion of developing fast, accurate, and reliable COVID-19 testing methods into the new CoV-SCAN Rapid Antigen Test. While PCR tests take days to reveal results and require complex and expensive equipment, antigen test enables early detection in an acute coronavirus infection, enabling healthcare providers to administer faster and accurate treatment methods. Knowledge of active infection in the fastest time possible is epidemiologically important and is crucial in controlling the spread and management of the COVID-19 pandemic

Features & Benefits

BioMedomics’s CoV-SCAN helps in detection of extracted nucleocapsid protein (N-protein) antigens specific to SARS-CoV-2 in nasal swab specimens directly collected from individuals who are suspected of COVID-19 by a healthcare provider within the first five (5) days of symptom onset. 

Given the worldwide surge of variant infections, it is particularly significant that CoV-SCAN is able to detect SARS-CoV-2 variants that pose a threat to the resurgence of COVID-19 infections. Variants of concern detected include Alpha (B.1.1.7) and Delta (B.1.617.2, AY.2) and variants of interest detected include Iota (B.1.526) and Mu (B.1.621). It was observed that not only were all variants of concerns detected by CoV-SCAN, but all they were detected at equal or up to 8-fold better sensitivity than the original, isolate virus (WA1).

FAQs

CoV-SCAN is a lateral flow immunochromatographic assay for the detection of extracted nucleocapsid protein (N-protein) antigens specific to SARS-CoV-2 in nasal swab specimens directly collected from individuals who are suspected of COVID-19 by a healthcare provider within the first five (5) days of symptom onset.

Nasal swab specimens require a sample preparation step (extraction) in which the sample is eluted into the lysis buffer solution. Extracted sample is added to the sample well of the test cassette to initiate the test. When the sample migrates in the test strip, SARS-CoV-2 viral antigens bind to anti-SARS-CoV-2 N-protein antibodies conjugated to indicator and capture particles in the test strip, forming an immune complex. The immune complex is then captured by the test line on the nitrocellulose membrane as it migrates through the strip.

Test results are interpreted at fifteen (15) minutes after sample addition. The presence of two (2) colored lines in the control line region (C-Line) and test line region (T-line) indicates the sample is SARS-CoV-2 positive. The presence of one (1) colored line, C-line, indicates the sample is SARS-CoV-2 negative. The absence of the C-line indicates an invalid test, and the sample must be retested.

Results are valid 15 minutes after sample and buffer are combined in the cassette sample well.

A total of three detection lines are possible, with the control (C) line appearing when sample has flowed through the cassette.

1 | Invalid Result: If the quality control line (C) does not appear, then the test result is invalid and sample must be retested with a new cassette.

2 | Negative Result: If only the quality control line (C) appears and the detection T line is not visible, the sample does not contain novel coronavirus antigens or the antigen concentration is lower than the limit of detection and the result is negative.

3 | Positive Result: If both the quality control line (C) and the detection line T appears, then the novel coronavirus has been detected and the result is positive. Result should be determined by whether the T-line is colored or not regardless of the color intensity

For best results, use a combination of the BioMedomics’s COVID-19 IgM/IgG Rapid Test to test for the detection of antibodies in human serum, plasma, or whole blood along with the CoV-SCAN Rapid Antigen Test for the detection of active infection. Combining the results of both a rapid COVID-19 Antigen and a rapid COVID-19 Antibody test, will give both the patient and healthcare provider the most accurate understanding of the patient’s health.

FAQs

The COVID-19 Antigen Test (LFIA) is an antigen test used to aid in the diagnosis of an active coronavirus infection via a lateral flow immunoassay (LFIA). The test detects the presence of the novel coronavirus antigens via nasal or nasopharyngeal secretion and provides diagnostic results within 15 minutes.

The test cassette contains (1) colloidal gold-labeled anti-SARS-CoV-2 antibody and quality control antibody colloidal gold marker, (2) one detection line (T line) and one quality control line(C) fixed on a nitrocellulose membrane. T is fixed with anti-SARS-CoV-2 antibody for detecting the novel coronavirus. The quality control antibody is fixed on the C line. When the appropriate amount of test sample treated with lysis buffer is added to the sample well of the test cassette, the sample will move forward along the test strip via capillary action. If the sample contains the novel coronavirus antigens and concentration of antigens is higher than the limit of detection, the antigen will bind to the colloidal gold-labeled anti-SARS-CoV-2 antibody. The immune complex will be captured by the anti-SARS-CoV-2 antibody immobilized on the membrane, forming a red T line and indicating a positive result for the novel coronavirus. If the sample contains no novel coronavirus antigens or the antigens concentration is lower than the limit of detection, a negative result is displayed.

Results are valid 15 minutes after sample and buffer are combined in the cassette sample well.

A total of three detection lines are possible, with the control (C) line appearing when sample has flowed through the cassette.

1 | Invalid Result: If the quality control line (C) does not appear, then the test result is invalid and sample must be retested with a new cassette.

2 | Negative Result: If only the quality control line (C) appears and the detection T line is not visible, the sample contains no novel coronavirus antigens or the antigens concentration is lower than the limit of detection and the result is negative.
