Are biological age tests accurate?

Accuracy of biological age tests is measured in three ways: Are the results relevant for long term health outcomes? Are they reliable with low repeat measurement error? Are they personalised and relevant to me as an individual based on my age, gender and ethnicity? GlycanAge meets all three criteria. It associates well with prediction of future health conditions and future risk of hospitalisation, performing better than the majority of other ageing clocks and traditional clinical biomarkers. We place quality and accuracy over profit, performing multiple tests on each sample to ensure your results are the most trustworthy measure of biological age available, with an error margin of less than 1%. Any change in your score is a reflection of a true biological change, not an error margin.
GlycanAge was developed from over 30 years of research, results in 200+ supporting peer review publications and a robust baseline of 200,000 samples from some of the world's best biobanks with comprehensive representations of different ages, genders and ethnicities.
