What are in vitro tests?
In vitro tests are a type of scientific test performed in the laboratory. There are two components that must be present in order to qualify as a test in vitro. First, the test must be performed in vitro, which means in a tube or other sterile container than in a living organism. Second, the test must be a test, which means that this is a measure of drug activity on the sample of organic tissue. These tests are useful in the development of new drugs, because those that are ineffective can be quickly excluded, which allows scientists to focus their attention on those that may prove successful.
The process of launching a new drug is complicated and time consuming. The use of tests in vitro will significantly shorten the time required to exclude an inefficient drug. Tissue samples such as organ or blood parts may be infected with disease and potential treatment can be administered into the samples. Displaying the interaction between the sample sample in the tube allows scientists to quickly determine whether the drug has the desired effect. Drugs whoThey show promising, then they can move to other phases of testing, while those that seem not to work can be abandoned.
In addition to accelerating the process of testing new drugs, in vitro tests also reduce the cost of drug development. The use of tissue samples allows you to perform many tests at the same time. In the vitro test it is possible to use samples that can be supplemented, such as blood samples. Although many of these samples are taken from animals, the cost of animals for testing in vitro testing is much lower than for in vivo tests.
In vitro tests can use human tissue samples. Testing on living people is often medically unethical, but tests can be performed on human blood samples or other tissue samples taken from the corpses. The use of human tissue E enables scientists to gain better understanding of how a certain drug affects human cells. Although testing still requires in vivo, the results that showed upY be promising during in vitro parts of tests, they may indicate whether the new drug will be effective in human patients.
