How Does an Oral HIV Test Work? - where can i buy an oral irrigator

When the CDC announced in September 2006 that everyone between the ages of 13 and 64 should be regularly tested for HIV as if they had a normal heartbeat or high cholesterol test, it caused a little buzz in the medical community.
While most health experts commend the proposal in principle, extensive, regular HIV testing for people who are not generally considered at risk can create problems.
Testing can be expensive, time-consuming (
For patients, doctors and laboratories)and upsetting.
Some people just don't have the heart to get stuck.
At least at the last point, there is a viable solution: the recent FDA-
Approved rapid HIV testing (
One that does not need to be sent to the lab for processing)
The same accurate blood, serum or oral liquid can be used.
A simple swab of the mouth and gums is everything that OraSure OraQuick needs to test in advance, the only HIV test approved for oral use as of September 2006.
Depending on who you ask, the oral test is either as accurate as the blood or partially inaccurate
Based on the test, false positive was slightly more likely than false negative.
Saliva is not used for the OraSure test.
It uses a liquid called oral mucosa transfer fluid, which is present in the cheeks and gums.
In addition to the liquid used for testing, the oral HIV test works like an HIV blood test ---
It is the test of HIV antibodies, not the actual disease.
When a person is infected with HIV, his or her immune system produces antibodies to try to kill the virus (
Understand how your immune system works to understand the antibody response).
So if a person has HIV, he also has HIV antibodies.
Although the oral fluid of the infected person does not contain almost any HIV virus ---
That's why kissing doesn't spread disease. -
Contains a large number of HIV antibodies.
The thing about making antibodies a good substance worth testing is that when the immune system produces antibodies against proteins for specific diseases (called antigens), in order to fight this disease, antibodies bind to these antigens.
If you add another protein or enzyme to the mixture that reacts to antibodies and antigens, you can do a good test of the disease yourself.
This is basically what oral HIV tests do.
The OraQuick Advance device comes with a test strip.
On the test strip inside the plastic shell, a substance with an HIV antigen component has been applied.
The patient placed the end of the test strip in his mouth and wiped his cheeks and gums.
The test administrator then places the end of the device in a vial containing an enzyme solution that responds to any antibodyAntigen binding.
When the oral liquid and enzyme move up along the test strip, they encounter HIV-
Antigen substance.
If there are HIV antibodies in the oral liquid, they start to bind to the antigen, and the enzyme reacts, resulting in a change in the color of the strip.
This generates a line on the reading.
Out part of the device.
This line represents a reaction. -
It is not considered a clear affirmation.
As with all other HIV tests, OraQuick needs to have a repeat test before the patient is considered HIV positive.
If no line appears at the location of the antigen substance, this is considered a negative result (
No HIV antibody).
Oral HIV testing takes 20 minutes to get the results.
There is no OraQuick device on the counter and should not be used for home testing.
For oral HIV testing, you should go to a doctor or to a clinic that provides services.
After this test, you still have to go back to your doctor and look for more specific tests because HIV antibodies may not appear until three to six months after the infection.
