The ion is derived from saline. It can also be found in gold particles, and even paper coated with antibodies. The Dr. Kate Biberdorf performs an in-home COVID test. Dr. Biberdorf explains how this process works.
First, you need to clean your throat. A doctor named Michael Mina has suggested that patients swab their backs of their throats as well in order to determine the presence of this particular Omicron variation to gather the most viral burden. After that, you apply an acidic buffer. The buffer solution will lock in the pH at 7.4, which has the same pH level as blood. This allows the pH to replicate the physiological conditions that the human body is in.
After a certain amount of time and enough time has passed, you’ll be able be able to check the results. It will show a tiny space with the letter “s” that contains tiny gold particles have been joined to an antibody. This antibody is able to bind the virus covid in an attempt to keep the virus from moving and yields a positive response.
Rapid tests are easily altered using a substance like soda or juice that has less pH. This can be reversed by using the buffer solutionby shaking it along the “T” line of the test and causing the results to return to the real thing.
