EXPLAINING DIFFERENT COVID-19 TESTS 1- PCR: The most accurate test available for detecting COVID. Nasal/Mouth sample needed. 150,000 LL set by Ministry of Health. Used also for travelling at borders. Very useful if done 4-5 days after exposure. 2- Rapid Ag Test: A quick test to see if someone has COVID. Patient MUST have symptoms; else the test is not accurate enough. 50,000 LL set by government. If +, no need for PCR anymore. Nasal swab or throat swab. 3- COVID Antibody Test IgG and IgM: Dosage testing for IMMUNITY. These antibodies arise 2 weeks to 1 month after an infection. Positive IgM means it was more recent (i.e. 2 weeks), whereas a positive IgG means it was more distant (1 month). Presence of Immunity may not last long for COVID. This is a blood test. A positive IgG means you may not need the vaccine. ALL TESTS AVAILABLE AT STMARC, HOUSE CALLS PRESENT (03-238887)

The New Corona as described, began in WUHAN city of China in late December 2019. It is a new genetic variety of the older SARS Corona that hit in 2013, killing 800 people then. The new variety this time, is faster to spread between people, but less deadly, as its mortality is only 2.8% Common and fast tests in routine labs have not been developed yet, but the MOH in Lebanon has already set up a hotline where Nasal Swab samples can be sent via labs in Lebanon. At the time of writing, 8000 infected cases have been confirmed, mostly east Asia, 180 deaths; zero cases in middle east.

Influenza A (includes H1N1) and type B are the flu viruses commonly effecting patients in the winter season. Usually hit the upper respiratory tract, with runny stuffed nose, soar throat and mild cough and fever. More serious in those with weak immune system. To test if one has this virus, a swab sample is taken from the nasal cavity (where the virus is) and tested within 1/2 hr for the presence of either type of Influenza.


A new test in the laboratory was added to our test menu: MGP. It is a new test to diagnose calcifications inside the blood vessels, which may lead to a hidden risk for heart attacks. For this reason a lecture was organized in the St Marc new auditorium, where 120 doctors attended to hear about the uses of the test and management.

STMARC History


History and Today, 36 years after its establishment:

Established in 1978, St. Marc has been the first diagnostic medical center in Lebanon after it added a radiology dept. to its already existing medical laboratory which was opened in 1976. Several years later it added a professional echography unit combining three units in one.

From that time on, St. Marc Medical Diagnostic Center has continued to flourish. It currently has 30 different medical diagnostic departments in its Zalka and Jetawi branches combined, equipped with the most sophisticated and up-to-date machinery.

All of our departments have been ISO 9001:2008 certified since 2009, making us the first full medical diagnostic private center to acquire this certificate. In the year 2000, St. Marc also was the first to go online with its results, providing patients, doctors and insurance companies a secure and effortless link to the data they require.

In 2008, a new Nuclear Medicine dept was established in the Zalka branch, where all scintigraphy procedures are performed including: thyroid, bone, kidney, and cardiac. 2011 saw the installment of two new Cone Beam (CB-CT) scanners in Zalka and Jetawi, giving St. Marc the latest technologies in both quality of 3-D imaging and patient comfort. A new semi-open advanced MRI unit (PHILIPS, see images) was also installed in Jetawi allowing St. Marc to perform various new MRI imaging procedures with the highest image resolution available currently. Recently, the laboratory dept saw the addition of five new tests which were not available in Lebanon to its vast list of blood tests(which count more than 400 tests), making it the first to perform them locally rather than outsource them (AMH, Quadruple Test, HE-4, and Anti-MCV, Calprotectin). St. Marc has been a pioneer in medical diagnostic tests by quality and services. The future will see the continuation of this trend.
