Are TikTok Age Tests Legit? Orthopedists Explains How to Measure Biological Age

Direct-to-Consumer biological age tests claim to measure molecular changes that indicate how fast a person's body is aging through blood or saliva samples.
These tests arose amid scientific advances yet lack standardization and often correlate with chronological age rather than true biological age.
Experts including Dr. Mark Lachs caution that these tests have limitations, suspect bias in test-takers, and advise they be used mainly to motivate healthier habits.
Tests usually cost between $200 and $500, and while epigenetic clocks predict disease risk at the population level, individual results show significant variation.
Specialists predict that within a decade, better tests correlating to biological function and feeling will emerge, but recommend proven health practices for now.
