What is an In Vivo Test?

In vivo means "within the living", so it makes sense that an in vivo test is one that is performed within the body of a living model. In vivo models can include animals as well as rodents, rabbits, or other complex mammals.

How Is In Vivo Testing Different From Others?

Now that we know what an in vivo test is, let's examine how they differentiate from other test options. There are different types of tests that can be used for Drug Discovery, including in vitro testing.

What is an in vitro study?

In vitro studies are those that are performed outside of a living organism. Traditionally they are considered more economic compared to in vivo tests.

Is it ethical to do in vivo tests on animals?

If we see this from an ethical point of view in terms of animal rights, in vivo tests are more acceptable when applied to these beings and not to other animals such as rodents, as they are not subject to stress and other types of suffering.

Is in vitro and in vivo testing complementary?

However, in vivo and in vitro tests can be complementary in some cases, depending on the application. Let’s take a look at some of the advantages of each option:

In vivo means "within the living", so it makes sense that an in vivo test is one that is performed within the body of a living model. In vivo models can include animals as well as rodents, rabbits, or other complex mammals. This is an essential process for Drug Discovery, as it clearly reflects the effect of the different compounds on …

What Are Zebrafish and How Are They Related to in Vivo Testing?

  • To reduce the use of rodents, rabbits, and mammals in laboratories, and to follow 3Rs guidelines, scientists have turned to zebrafish, which is an animal whose anatomy favors some preclinical studies, such as in vivotesting. These fish serve as bridges between in vitro and in vivo testsand, compared to some rodents, are adaptable to various conditions and environments. This means t…

How Are Zebrafish Different from Other Laboratory Animals?

  • In addition to the above, the embryos of a zebrafish are not considered as animals until they are six or seven days old, which is when they can feed independently. If we see this from an ethical point of view in terms of animal rights,in vivotests are more acceptable when applied to these beings and not to other animals such as rodents, as they are not subject to stress and other type…
