David Propert – Osteopath
I am really pleased to be able to offer the Covid-19 (SARS-Cov-2) Antibody Test through our lab partner, The Doctors Laboratory (TDL). This uses the Abbott’s analysis kits which are suitable for home use, with the sample returned to the lab by post. This is the only Public Health England (PHE)-approved antibody test for Covid-19 available outside the NHS.
Molecular testing (PCR nasal/ throat Swab) identifies people with the live virus who will therefore be contagious to others. Antibody testing (for IgG in this case), using a small (finger-prick) blood sample can tell whether a person has been previously infected. Most patients who recover from coronavirus have been found to produce antibodies, but it is not yet known if an individual with a positive result showing presence of IgG levels following being infected with SARS-CoV-2 will be protected, either fully or partially from future infection, or for how long protective immunity may last. Testing should be undertaken 14 days or more following exposure or onset of symptoms. The incubation period of COVID-19 ranges from between 1 to 14 days, with the majority of cases manifesting with symptoms at 3 – 5 days. The most common symptoms of COVID-19 are fever, tiredness, dry cough, difficulty breathing and anosmia. These symptoms have the potential to develop into a very severe acute respiratory illness. Evidence shows that fatality rates increase with age, gender, body weight, ethnicity and comorbidities.The host immune system reacts to the infection by SARS-CoV-2 by producing antibodies from a few days to 2 weeks and beyond. Specific IgG antibodies are produced in the later stages of infection to SARS-CoV-2, and are detectable after RNA (swab test) is no longer detectable. The persistence of IgG antibodies allows identification of people who have been infected by SARS-CoV-2.
The test has a Specificity of 100%. This means that if the test result is positive, the person has had a definite exposure to the virus with IgG antibodies produced (so no false positives). The test has a Sensitivity of 97.5% which, currently, is the best there is. This translates into a very small chance of a false negative result which means a person who, in fact, does have IgG antibodies to Covid-19 might test negative.
The process: A test kit is sent to your home for self-administration (instructions are enclosed) which involves taking a few drops of blood from a finger. This is applied into the sample vial which is then sent back to the lab in a reply-paid envelope along with a referral form from me. The turnaround time is around 24-hours. Once the sample is taken, it MUST be analysed within 6 days. TDL (based on Wimpole Street) are also accepting kit deliveries in person if that is easier. The turnaround time is around 24-hours with the result emailed to me. I am charging £50 for the test.
