COVID-19 TEST

Feb 08, 2021
Testing for the disease COVID-19 is also done with the immunochromatography method, the well-known rapid tests. The result is available in 5 minutes. The sensitivity of the method is 92% and the specificity is 98%.

PCR Molecular Test at Home (COVID-19 PCR Test)

The PCR test identifies the virus’s genetic material (RNA) in an individual’s body through polymerase chain reaction (PCR). This test helps determine whether someone has already contracted COVID-19. You can perform the molecular test at home if you are showing symptoms (testing is recommended after 48 hours of symptom onset) or if you have been exposed to the virus, even without symptoms.

Healthcare professionals use the One Step Real-Time PCR method to detect COVID-19 RNA, following WHO and CDC guidelines. They collect a nasopharyngeal or oropharyngeal swab, ideally 48 hours after the symptoms begin. Because nasopharyngeal swabs offer more reliable results, they are typically preferred.

PCR testing provides the most reliable way to detect the coronavirus, offering 99% sensitivity.

Rapid Antigen Test at Home

The rapid antigen test detects the virus in samples taken from the upper respiratory tract. It is most effective when the coronavirus infection peaks in its acute phase. Therefore, healthcare workers perform this test using a nasopharyngeal or oral swab.

This test offers an easy-to-use solution and provides quick, reliable results. It works using immunochromatography or immunofluorescence methods.

  • A positive result indicates an active infection.
  • A negative result shows no viral proteins were found. However, if you display symptoms, it is best to confirm this with a molecular (PCR) test.

Result Time: You will receive the rapid antigen test results within 15 minutes, offering a fast response time.

Antibody Test at Home

The antibody test detects two types of coronavirus antibodies: IgG and IgM.

  • IgM antibodies typically develop around the 7th day of infection, indicating recent exposure to COVID-19.
  • IgG antibodies usually develop 15-28 days after symptoms begin and remain in the blood for months, signaling a past infection.

SOS Doctors offer antibody tests for both IgM and IgG antibodies, either individually or combined.

This test does not detect an ongoing infection. Instead, it determines whether someone has been infected and might have developed immunity to COVID-19.

Healthcare professionals will collect a blood sample, and you can expect results within 24 hours.

How to Self-Administer a Rapid Test at Home


Fast COVID-19 TEST

  1. First, sterilize your hands thoroughly.
  2. Then, pour the entire solution from the bottle into the extraction tube.
  3. Next, insert the swab into your nose, reaching the back of your throat, and collect a sample by rotating the swab several times.
  4. Stir the swab in the extraction tube for 15 seconds or as instructed in the test kit.
  5. Afterward, close the cap tightly and shake the tube well.
  6. Now, add 3 drops of the solution to the sample port.
  7. Finally, wait for 10 minutes to see the results.

Positive Self-Test: Two red lines will appear, one in the control area (C) and one in the test area (T).

Negative Self-Test: Only one red line will appear in the control area (C), and no line will appear in the test area (T).

Invalid Self-Test: If no red line appears in the control area (C), the test is invalid, even if a line appears in the test area (T). You must repeat the test in this case.
