AbC-19™ Rapid Test and vaccines

Vaccines “train” the immune system by using harmless viruses that have been altered to resemble dangerous ones. In the case of SARS-CoV-2 vaccine developers have focused on mimicking the Spike protein. Three of the leading vaccine candidates all feature full-length SARS-CoV-2 spike trimers: Oxford University / AstraZeneca, Pfizer / BioNTeh, and Moderna.

Professor Lawrence S. Young, Virologist at University of Warwick Medical School:

”The AbC-19™ Rapid Test targets the IgG antibodies to the full spike protein of the SARS-CoV-2 virus and therefore has the potential to help identify the immune system’s response to the current three Medicines and Healthcare products Regulatory Agency (MHRA) approved vaccines.

The assay could help establish whether people’s immune systems are responding to the vaccine in the right way, and, ultimately, could be predictive of a protective immune response”

  • If taken at least 14 days following the onset of symptoms then the AbC-19™ Rapid Test has a sensitivity of 98.03% and a specificity of 99.56%. More details here.

    As detailed in the table below a known population of 450 negative samples were tested alongside 203 known positive samples. The positive population of 203 samples were obtained from donors at least 14 days after the onset of COVID-19 symptoms and were verified as positive using a commercial IgG SARS-CoV-2 ELISA kit.

    Positive Negative
    ELISA Positive 199 4
    Negative 2^ 448*

    * 98 pre-pandemic negative samples not tested by ELISA
    ^ 2 pre-pandemic negative samples not tested by ELISA

    Clinical Sensitivity and Specificity is as follows:
    Positive Predictive Agreement (Sensitivity): 98.03% (95% Cla : 95.03% – 99.46%)
    Negative Predictive Agreement (Specificity): 99.56% (95% Cla : 98.40% – 99.95%)

    Cross reactivity:
    Known positive serum samples from other viral infections were tested as follows (value in square brackets refers to the number tested) Seasonal Coronavirus (HCoV-NL63 [x5] and HCoV-229E [x5]), Influenza A [x5], H5N1 Influenza [x1], influenza B [x6] Respiratory Syncytial Virus (RSV) [x6], Haemophilus influenzae type b [x5] and Bordetella pertussis [x1]. No cross reactivity was observed, with all tests demonstrating a negative result using the AbC-19™ Rapid Test.
    Interference: A range of substances were tested using the AbC-19™ Rapid Test for positive and negative interference. No false positives or false negatives were recorded at the concentrations in the table below;

    Substance Upper limit of normal serum levels mg/dL Level Tested mg/dL
    Unconjugated Bilirubin 2 40
    Cholesterol (total) <200 400
    Triglyceride 200 1,500
    IgG 1,400 4,200
    IgM 250 750
    Haemoglobin 17.5 1,000
    Biotin 0.117 0.351
    Acetaminophen (paracetamol) 5.2 15.6
    Acetylsalicylic acid (asprin) 1 3
    Ibuprofen 7.3 22
    Caffeine 3.6 11
  • From a finger-prick sample of blood, AbC-19™ antibody rapid test detects the SARS-CoV-2 IgG neutralising antibodies to the full spike protein produced in response to the virus or following vaccination. The rapid antibody test will determine if the body has produced a measurable immune response indicating a previous infection with COVID-19 virus or vaccination. It will not confirm if you are currently infected by the virus.

  • The line closest to the sample hole is the test line (T-line). The presence of a T-line alongside a C-line is a POSITIVE result, the absence of a T-Line alongside a C-line is a NEGATIVE result.
