In vivo is a test that is done inside a living person and an example is testing out a new drug on humans. In vitro is done within the glass such as cellular Biology studies.
An in vivo test is a test in a live subject, as opposed to in vitro tests done in the lab.
Some enzymes behave unnaturally in a test tube (Apex).
The opposite of "in vitro" (literally in glass) is "in vivo" (in life).
it is vitro-in-vivo correlation

"in vitro" means "in glass" "in vivo" means "in life." The simplest example is drug development. The first stages are all done in vitro, but then it has to be checked and verified in vivo, and usually even the most promising drugs don't work out, either because they don't work as hoped, or because they also have bad effects that weren't predicted.
In vivo means a process which takes place inside a living organism, as opposed to in vitro, which means it takes place outside the organism. For example, human babies are usually made in vivo, but some people have to use in vitro methods for various reasons.
Something that is 'in vitro' was grown outside of a living organism. it is synonymous with 'ex vivo', making this definition even more obvious. ------------------------------------------------------------------------------------------------- If it's the basic translation you were looking for: "In vitro" simply means "In glass"
Invitro tests are carried out using cells, enzymes or isolated receptors as target for the substance under test. The advantages include small test sample to be used, no need for ethical consideration and ease of operation which facilitates bioassay guided isolation of active compounds
The term in vitro means " in an artificial environment, outside the body."add Literally it means "in glass", as distinct from "in vivo" within the body.

Pseudomonas meningitis (in vitro). It has been reported in vivo only a few times.
