There is a new color test out there that could detect
whether someone has low levels of a virus such as HIV and certain cancers. The
color of a liquid test changes to give either a positive or negative result. Designers
from Imperial College London say that the device could lead to more widespread
testing for HIV and other diseases in parts of the world where other methods
are unaffordable. The test can be configured to a unique signature of a disease
or virus- such as a protein found on the surface of the HIV. Researchers say
this allows the results to be detected with “the naked eye”. Early testing
showed the presence of markers of HIV and prostate cancer could be detected.
Researchers expect their design will cost 10 times less than current tests. According
Dr. Roberto de la Rica “this test could be significantly cheaper to administer,
which could pave the way for more widespread use of HIV testing in poorer parts
of the world.”
With advancements of that sort, that will take us very far
in the medical world. Not only will that help us out in countries that lack the
medical attention it could help prevent so many more disease as well. Looking
into the future when this truly becomes mass produced, and has been perfected
to the max, it will truly bring hope to third worlds countries. These things
are the baby steps into bigger steps that truly bring change into the world. With
this recent discovery, they will be able to bring progress in other countries.
Imagining 5 years how this could be distributed it will not only be able to diagnose
diseases it will prevent, and we might be able to slowly stop it from
spreading. Things like these will truly bring hope to the world.
