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.

Whole Body Bone Denistometry
Densitometry is the quantitative measurement of radio-density in bone. 3 areas of the body are measure by a specialized densitometer: femur, vertebrae and forearm to assess if there is any osteopenia or osteoporosis. Results are delivered with a colored graph and on the spot.
General Radiology
Radiology is a medical specialty that employs the use of imaging to both diagnose disease visualized within the human body. Radiologists use an array of imaging technologies (such as x-ray radiography, digital imagery).
CT Scan
X-ray computed tomography (CT) is a medical imaging method employing tomography created by computer processing.Several X-Rays are taken per area of the body and joined together by the computer to form a more apprehensive picture of the area involved (e.g. brain...).
ANA Pathology
Anatomic pathology is a medical specialty that is concerned with the diagnosis of disease based on the gross, microscopic, chemical, immunologic and molecular examination of organs, and tissues.
General Echography
Medical sonography (echography) is an ultrasound-based diagnostic medical imaging technique used to visualize muscles, tendons, and many internal organs, to capture their size, structure and any pathological lesions with real time images. Ultrasound has been used by radiologists and sonographers to image the human body for at least 50 years and has become one of the most widely used diagnostic tools in modern medicine. Echo machines have been upgraded constantly in St. Marc over the years to include the latest technology for the radiologist, and best quality pictures for the treating physician and patient. Recent addition included the 4-D imaging used for Obstetrical morphology of the fetus with superb clarity.
Mammography
Mammography is a specific type of imaging that uses a low-dose x-ray system to examine breasts. A mammography exam, called a mammogram, is used to aid in the early detection and diagnosis of breast diseases in women. 2011 saw the upgrading of all Mammography machines in all three branches to a digitalized system, ensuring a shorter stay for the patient with up-to-date technology.
Audiogram
Audiograms are produced using a piece of test equipment called an audiometer, and this allows different frequencies to be presented to the subject, usually over calibrated headphones. It is a device that with the collaboration of the patient assesses if any hearing loss is present.
Cardiac stress test
Cardiac stress test is done to assess the cardiac function under a "stressful" situation such as mild-moderate exercise. A cardiologist will monitor a live ECG while the patient performs a physical exercise. It is a simple and non-invasive procedure, with results being available instantly.
ECG
The electrocardiogram (ECG or EKG) is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart. While it is a relatively simple test to perform, the interpretation of the ECG is completed by a specialized cardiologist.
EEG
Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain.In clinical contexts, EEG refers to the recording of the brains spontaneous electrical activity over a short period of time, usually 20–60 minutes, as recorded from multiple electrodes placed on the scalp. EEG measurement at St. Marc is performed with live simultaneous video monitoring to rule out false-positive spikes during voluntary motion (coughing...).
Echostress
Recently, St. Marc acquired the latest technology in Echostress testing: While the patient is lying down, a gradual cycling is started by the cardiologist, who performs the cardiac echography on-the-spot, with a simultaneous ECG showing on a monitor. This is different from threadmill use in other centers, since by the time the patient moves from a threadmill to the echo machine, part of his heart has relaxed resulting in less accurate results.
Cardiac color doppler
An echocardiogram (often called echo) is a graphic outline of the hearts movement. During this test, high-frequency sound waves, called ultrasound, provide pictures of the heart valves and chambers. This allows the cardiologist to evaluate the pumping action of the heart. Echo is often combined with Doppler ultrasound and color Doppler to evaluate blood flow across the hearts valves.
