A lot of confusion exists among people regarding the difference between all the tests relating to COVID-19. Here is the difference between a rapid antigen test and a PCR test:
Rapid antigen test (RAT):
Rapid antigen test (RAT) detects specific viral antigens on the virus's surface from a swab of the mouth and nose of a patient. An antigen test can determine if you are carrying the Coronavirus. The FDA approved the antigen test for emergency use in May 2020. However, these tests aren't as accurate as a regular PCR test (PCR has an accuracy rate of 95% while the antigen test has an accuracy rate of 73%), and they produce higher chances of getting false positives (meaning the test will show you have COVID-19, but you actually don't).
A polymerase chain reaction (PCR):
The covid PCR test is a test that detects genetic material from COVID in swabs taken from the patient's nose and mouth.
How does it work? COVID is a virus containing RNA as genetic material. In a PCR test, scientists convert the viral RNA to DNA through 'reverse transcription. A PCR is highly accurate and has a very low rate of false positives. This is considered the "gold standard" for diagnosing COVID. It is one of the fastest and most accurate tests for Covid-19.
EMA Care has helped many people get the Covid-19 test done accurately and adequately. We have also helped many people who entered Israel to get both Covid-19 PCR tests and antibody testing. These two tests are required if you wish to enter Israel.

Thank you for the zoom (and all your updates). It was great. I wish the news was like that. Straight forward, factual, unemotional. Bravo to both of you ladies!!
My experience with Ema Care has been so positive that I wanted to share it in case it could help someone else. Eight days ago my daughter, a Shanah Bet student, called to say she wasn’t feeling well and had symptoms of Covid-19. I was put in touch with an Infectious Disease specialist who recommended Ema Care. I reached Dr. Eliana Aaron easily and signed my daughter up. The next morning, Ema Care gave my daughter a telehealth exam and provided her with prescriptions, as well as a list of...
I would like to also add my compliments, you exceeded my already very high expectations. You can certainly send other schools our way for a recommendation.

Dear Dr. Eliana words simply cannot express how much you have done for all of us and so many others in keeping us informed, calming anxieties, and being such a wonderful and patient resource through such a difficult time.

Hello Dr. Aaron. I cannot thank you enough for providing not only crucial information but a framework that gave us stability and allowed us to function (instead of descending into chaos, which undoubtedly would have happened, if not for you). At the risk of waxing dramatic, I will tell you that when I think of what you've done these past couple of months, what comes to mind is Rav Yohanan Ben Zakai asking Vespasian to give him Yavneh ve-Hakhameha, thus saving the entire enterprise of Talmud...
