Animal testing has been the only reliable way to check drugs for so long that we still rely on it in the 21st century. Despite the present-day technology comes way ahead of raising guinea pigs, animal testing has deeply settled in scientific minds. Nevertheless, there are effective and affordable alternatives to what has become an ethical concern over the years.
In vitro tests allow scientists to grow human cells and tissues outside the human body. Their reaction to chemicals more accurately illustrates the response of a human body. Parts of human skin and organs can be grown in labs, which allows testing all kinds of substances without causing any harm to human or animal testers. Another alternative is in silico computer-modeled tests. These are programs that anticipate the potential response to substances based on the information scientists already have. They are not as reliable as in vitro tests but still make a good substitute for animal testing.
