What is the minimum age at which a person can donate a part of their body without parental consent?

In Missouri, the minimum age at which a person can donate a part of their body without parental consent is indeed 18 years. This aligns with the general legal principle that individuals attain the status of adulthood at 18, granting them the legal capacity to make personal decisions regarding medical treatments and donations, such as organ and tissue donation.

At this age, individuals can independently consent to the donation of their body parts, recognizing their ability to make informed decisions about their own bodies and health care. This age restriction is significant as it reflects the legal framework set by state law to protect minors, ensuring that those under 18 are not making such serious and impactful decisions without guidance and consent from a parent or guardian. Therefore, 18 years is the threshold established for individual autonomy in matters of body donation.
