Q# 2, WHAT TESTS ARE AVAILABLE FOR CORONAVIRUS INFECTION?
There are two main types. The first, an antigen test, detects the presence or absence in the body of the new coronavirus, which causes the disease Covid-19. The second, an antibody test, looks for signs that someone has been infected in the past by searching for an immune response. Since Chinese scientists in mid-January published the full genetic code of the virus — officially known as Sars-CoV-2 — laboratories anywhere in the world have been able to use antigen testing to identify its genes in samples from patients. They use a procedure called polymerase chain reaction (PCR) that has been standard practice in labs for 30 years. PCR samples can come from several different sites in the patient. Simplest is the nasal swab taken from well inside the nose. The back of the throat is another option. For patients in hospital, a sample from the lower respiratory tract may give the best results. Antigen testing reveals whether someone has a current infection and could therefore pass Covid-19 on to others.
In contrast, antibody (or serological) tests work on blood samples to detect the immunity conferred by past infection. The test kits use proteins from the virus as “glue” to trap antibodies present in blood, said Eleanor Riley, professor of immunology at the University of Edinburgh. A finger prick should provide enough blood to detect two types of antibodies against Sars-CoV-2. The first, IgM antibodies, are shortlived and may indicate that the virus is still present. They usually disappear a couple of weeks after infection. In their place emerge a second more durable type, IgG antibodies. No one knows yet how long these will last and provide resistance to reinfection — anything from a few months to a few years seems possible. Antibody tests are being prioritised by governments including the UK and Germany because they will be essential to informing individuals whether they can return to mixing safely in society without passing on or picking up infection. When carried out in a representative sample of the population, they will also answer key epidemiological questions — including about how many people were infected with mild or no symptoms. Once developed, antibody tests should give results more quickly than traditional PCR tests, taking a few minutes rather than a few hours, though much faster antigen kits are under development.

According to data from the Foundation for Innovative New Diagnostics (Find), a Geneva-based non-profit group that tracks product development, the second-largest number of Buy covid 19 test kits, which has 29. Find’s list is not exhaustive and does not include some major players that have not sought to appear. Among them are Nasdaq-listed Hologic, whose test the US Food and Drug Administration has authorised for emergency use. Beyond conventional antibody and antigen tests, researchers in universities and biotech companies are developing imaginative new diagnostic technologies.
