COVID-19 Antibody Test

Tempus Belgravia is pleased to be offering Covid -19 antibody testing. The tests are conducted by professionals and enable you to see if you have had previous exposure to SARS-Cov-2, the virus leading to the Covid -19 infection. The antibody test has a 100% sensitivity rate for past infections (IgG) and has a 97.5% accuracy rate.

The test is a blood test for Covid -19 (SARS-Cov-2) IgG antibody. The recommendation is for the test to be done in a clinical setting. We provide you with the antibody testing and the advice you need to support the antibody test results.

What does the antibody test look for?

Antibody testing can tell whether a person has been previously infected. Most patients who recover from Coronavirus have been found to produce antibodies; initially an IgM antibody and then the recovery phase IgG antibody.

The IgG Antibody

The IgG antibody in other viruses is found to be protective as these antibodies stay in the system as a form of defence. Whilst SARS-Cov-2 is a relatively new virus, scientists are working globally to establish and define the immunity status following an infection. Key areas of ongoing research:

  • If an individual has a positive IgG result following SARS-Cov-2 ; will they either fully or partially from future infection?
  • How long the protective immunity may last.

When can the Covid 19 antibody test be done?

Testing should be undertaken 14 days or more following exposure or onset of symptoms.

The immune system reacts to the SARS Cov-2 by producing antibodies from a few days to 2 weeks and beyond. Specific IgG antibodies are produced at the later stages of the infection to SARS Cov-2

The persistence of IgG antibodies allows the identification of people who have been infected by SARS -Cov-2. The test development relating to SARS-Cov-2 is rapidly evolving and The Mews Practice is in constant communication with updates from the approved laboratories used.

COVID-19 Symptoms

Symptoms include:

  • Fever
  • Tiredness
  • Dry Cough
  • Difficulty breathing
  • Loss of taste or smell
  • Bowel upset

The symptoms for COVID 19 is some cases have the potential to develop into severe respiratory illness. Evidence has shown that fatality rates increase with age, gender, body weight, ethnicity and the presence of underlying illnesses.

The Antibody Testing Process

You will be sent a simple pre- screening questionnaire and consent form. Tempus Belgravia will aim to do as much as possible in advance to avoid time within the practice.

When you arrive, the reception will call you in from the dedicated car park where you will be asked to:

  • Wear protective foot covering (automated for ease)
  • Wipe hands with alcohol product
  • Wear a mask
  • There will be no waiting

You will then enter a pre decontaminated treatment suite where the doctor will be in PPE. The Dr will verify the history and consent and take a blood sample using a relatively pain free technique using a butterfly. The blood sample is sent to the approved laboratory and the outcome is returned to the practice electronically within 48 hours to 72 hours depending on the demand on the laboratory.

Covid 19 Antibody Test Certificate

The Covid- 19 results will be forwarded to you by way of a ‘certificate of testing’ with a full explanation of the results. The clinicians at Tempus Belgravia will also ring or video call the patient if the results are positive.

How accurate is the Antibody test?

Medical tests are usually measured for accuracy by looking at two criteria Specificity and Sensitivity. The higher the percentage, the more accurate is the result.

Specificity for this test is 100% A highly sensitive test is one that correctly identifies patients with a disease. A test that is 100% sensitive will identify all patients who have the disease.

Sensitivity for this is 97.5% A test that’s highly sensitive will flag almost everyone who has the disease and not generate many false-negative results.

All results are interpreted in the context of the clinical symptoms. It has been recognised that there can be weak or delayed responses in patients who have conditions where the immune system is compromised
