Covid – 19 Antibody Testing at the CRP Clinic

Available from the 11th May 2020

What is a Covid -19 (SARS-CoV-2) Antibody Blood Test?

An antibody blood test can tell whether a person has been previously infected. Most patients who recover from coronavirus have been found to produce antibodies known as IgG antibodies. The majority of people with COVID-19 have uncomplicated or mild illness (81%), with non-specific symptoms such as fever, fatigue, cough (with or without sputum production), anorexia, malaise, muscle pain, sore throat, dyspnoea, nasal congestion, or headache. Rarely, patients may also present with diarrhoea, nausea and vomiting. Loss of taste and smell has been reported early in the infection.

Some people may not even know if they have had the infection, and by knowing your immune status, this may help in planning your health and medical requirements at least in the short term. It is not yet known if an individual with a positive result showing presence of IgG levels following being infected with Coronavirus will be protected, either fully or partially from future infection or how long protective immunity may last, but if the virus behaves like other known Coronaviruses, most likely the immunity will last for a reasonable time if not permanent.

Test Accuracy

  • Testing should be undertaken at 14 days or more after symptoms onset. The incubation period of Covid -19 ranges from between 1-14 days. The presence of IgG antibodies allows identification of people who have been infected by SARS-CoV-2.
  • The specificity of the test is 100% that is the ability of the test to correctly identify those without the disease (true negative rate).
  • The minimum test sensitivity is 98% that is the ability of a test to correctly identify those with the disease (true positive rate), making our offered test as one of the best available globally.
