==Key Stage 4==
===Meaning===
'''Preclinical Testing''' is when a potential [[drugmedicine]] is tested on [[tissue]]s grown in a lab or on [[animal]]s to determine a [[Medicine|medicinal]] effect, before using it on [[human]]s.
===About Preclinical Testing===
: '''Preclinical testing''' can indicate whether something may work as a [[medicine]] and whether it may be safe. However, even if the it passes this stage, it may still be ineffective on [[human]]s or be dangerous.
: Once '''preclinical testing''' is done successfully the potential [[medicine]] can then go on to [[Clinical Trial|clinical trials]] where it is tested on [[human]]s.
