Immunology testing for COVID-19

Immunology (serology) testing for SARS COV-2 is at increased demand in order to better quantify the number of cases of COVID-19, including those that may be asymptomatic or have recovered. Serology tests are antibody-based blood tests that can be used to identify whether people have been exposed to a particular pathogen by looking at their immune response.
Antibodies, also called immunoglobulins (Igs), are proteins produced by the immune system in response to an infection and are specific to that particular infection. The foreign stimulant is called antigen (Ag). A wide range of substances are regarded by the body as Ags, including disease causing organisms (bacteria, viruses etc.) and toxic materials such as insect venom. Specific proteins (Ag) from SARS-CoV-2 stimulate the immune system to produce an immune response, and corresponding antibodies (Abs) appear in the blood. Abs recognize and latch onto Ags (like a lock and key) in order to remove them from the body. A type of Ab, called IgM, appears first, and is mostly positive within few days of onset. IgM Abs are transient and become undetectable after few weeks. As IgM titers decrease, another type, IgG Ab, starts forming around the time of resolution of symptoms, and the level in blood continues to rise for a period. Generally, IgG remains detectable in a person’s blood, and usually offers future immunity against the specific virus.
Detecting different Abs may help in differentiating those recently infected (by detecting IgM and possibly IgA) from those that have had the infection in the past (IgG).
These tests are part of the second phase of the epidemic, where, after molecular biology tests(PCR) performed to detect the specific presence of the virus, serological tests must be used to identify the presence of antibodies against COVID-19 in patients. In the immediate future, these tests will be used to precisely define the population immune to the disease (herd immunity). At a later stage, they will enable the identification of individuals who will require vaccination when it becomes available.
Snibe Co (China) has developed 2 tests for COVID-19, the SARS COV-2 IgG and IgM fully automated Chemiluminescent Immunoassay (CLIA) Tests. The test is typically quantitative and needs 1 – 2 hrs for result
The test is CE/IVD approved.

HML fully automated state-of-the-art laboratories are specifically designed to meet the evolving needs of all healthcare facilities.
Built in 1980, HML’s initiative was strategically planned to meet the growing demand for both basic and advanced diagnostic testing in Beirut – Lebanon and the region, and reduce the requirement for international send-outs. HML lab was established in Hamra area,near the AUB Medical Center, which is one of the most advanced and renowned areas for medical care. It was established in order to create an efficient and high quality solution that is closer to home while reducing both turnaround times and logistical costs.
A molecular diagnostic section was introduced two years ago and features state-of-art, fully automated molecular diagnostic system. In this section diagnosis for different diseases, including genetic (mutations) and infectious diseases are performed.
