# GlycanAge > GlycanAge is a biological age test that focuses on immune system aging by analysing glycans, complex sugar structures attached to proteins in the blood. These glycan patterns reflect long-term changes in inflammation and immune function, both of which are closely linked to aging. ## Core Science - [Biological Age Testing](https://glycanage.com/biological-age-testing): Learn what biological age testing is, how it works, and the science behind aging biomarkers. - [Our Science](https://glycanage.com/about/our-science): Explore the research-led approach grounded in glycoscience and peer-reviewed studies. - [Publications](https://glycanage.com/resources/publications): Browse scientific papers and peer-reviewed research behind the technology. ## Clinical Studies - [Research Matrix](https://glycanage.com/research-matrix): A comprehensive database of studies linking glycans to aging and various diseases. - [Research Case Studies](https://glycanage.com/for-research/research-case-studies): Real-world studies showcasing how GlycanAge data empowers cutting-edge research. - [GlycanAge for Researchers](https://glycanage.com/for-research/glycanage-for-research): Information on how scientists use GlycanAge to unlock insights in aging and inflammation. ## Product Guides - [GlycanAge for Personal Use](https://glycanage.com/for-personal/glycanage-for-personal-use): Discover how your biological age compares to your chronological age. - [Shop](https://www.glycanage.com/shop): Choose the right package for starting your journey or optimizing long-term health. - [GlycanAge for Healthcare Providers](https://glycanage.com/for-providers/glycanage-for-healthcare-providers): Empower patient care with cutting-edge biological age testing. - [Sample Report (Female)](https://glycanage.com/personal-report-female.pdf): Preview a detailed, personalized biological age report.
