  • The antibody tests for specific “IgG” & “IgM” COVID-19 antibodies.

  • 99.6% accurate.

Immunoglobulin M (IgM) is the largest immunoglobulin in humans and is the first antibody to be produced upon infection. Since it has multiple antigen binding sites, it can be thought of as a ‘general’ antibody and is compatible with many pathogen species/types. In the case of COVID-19, IgM levels in the blood rise to a detectable level 3-7 days after infection, as symptoms begin to appear.

Immunoglobulin G (IgG) is a smaller structure and is produced in response to a specific antigen on the pathogen. Its levels rise later than IgM (>7 days) and indicates exposure to the SARS-CoV-2 sometime previously.

The result is positive for SARS-COV-2 virus specific-IgM antibodies and is indicative of early phase primary COVID-19 infection. Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status, a follow-up testing with a molecular diagnostic (PCR) test should be considered to rule out infection in these individuals especially if exhibiting any symptoms.

This test should be interpreted by a health care professional in the context of patient history and symptoms.

Positive result indicates previous exposure to SARS-COV-2, this antibody test is not a diagnostic tool for active infection. This test should be interpreted by a health care professional in the context of patient history and symptoms.

An absence of antibodies means that it is likely that you have NOT had COVID-19. An absence of antibodies infers an absence of immune defence to further coronavirus infections. 

COVID-19 Antibody test detects the presence of the SARSCoV-2 specific IgG and general IgM for the qualitative diagnosis of early and late stage COVID-19. As mentioned, IgG is specific to SARS-CoV-2 and confirms secondary illness (usually >7 days), whereas IgM confirms primary illness (3-7 days). Both are elevated in the secondary illness and can be used to confirm diagnosis.

Technical data for COVID-19 antibodies:

  • Accuracy: 99.6% 
  • Specificity: >99% while showing no cross-reactivity to non-SARS coronaviruses or other medical conditions.

COVID-19 PCR Testing for Business

COVID-19 PCR Tests for Business

We provide PCR testing to keep your workforce safe. A PCR test looks for the presence of genetic material from the COVID-19 virus within a swab or saliva sample to tell you if you have an active infection. 

PCR tests are being used to rule out COVID-19 infection before travel or resuming other activities. 

The COVID-19 PCR test requires a sample to be collected from the throat and sent to our UKAS registered laboratory for analysis. 

We provide results within 24 hours including Fit-to-Fly Certificates

A PCR test looks for the presence of genetic material from the COVID-19 virus within a swab or saliva sample. These tests are commonly referred to as polymerase chain reaction (PCR) tests. Antigen tests look for parts of the virus. 

The COVID-19 PCR test involves a swab sample to be collected and sent back to our partnered laboratory for testing.

PCR swabs are being used to rule out COVID-19 infection before travel or resuming other activities. We can issue certificates for travel within 24 hours from the time your sample arrives at the lab.

If your COVID-19 PCR test is positive our nurses will advise through the next steps. The employee will need to isolate as well as anyone who they may have come into close contact with.

For further guidance please visit NHS website here

A negative PCR test means that you were not infected with COVID-19 when you took the test. If you have no symptoms, you can continue as normal. However, if you have symptoms, follow NHS guidance.

Venous Blood Lab Tests: In clinical tests the Platelia SARS-CoV-2 Total Ab test demonstrated >99% specificity for SARS-CoV-2 while showing no cross-reactivity to non-SARS coronaviruses or other medical conditions.

In a study of PCR-positive patients, the assay detected antibodies in 100% of patients that were collected and tested between 9 and 22 days after onset of symptoms.

PCR Tests: These tests are 99.9% accurate and are approved by Public Health England.

Antibody testing looks for the presence of antibodies (produced by people with the virus to counteract the virus) against COVID-19 virus. The tests involves taking a finger prick blood sample which is then analysed for the presence of antibodies associated with COVID-19. (These tests should only be performed and interpreted by fully trained, healthcare professional).

Further advice on PCR & Antibody testing can be found on the government website here

Following any antibody test you must still follow government advice on social distancing, hand-washing and isolation.

Having antibodies simply makes it more likely that you will not have a second infection or, failing that, that a second infection would be milder compared with a similar person who has no such antibodies. However, it is still not proven that you immune from COVID-19 once you have developed the antibodies. 

We can arrange for your business to be tested within 1-2 weeks.
