DNA Methylation Testing

DNA methylation testing can provide a health marker beyond chronological age by measuring biological aging rate. DNA methylation tests are described as unreliable for health assessment and not ready for clinical use. DNA methylation test results are expressed as a ratio of biological days aged per calendar days elapsed. DNA methylation tests attempt to measure aging speed by analyzing blood samples for methylation patterns associated with cellular aging. A DNA methylation test measures how fast the body is aging relative to calendar time. DNA methylation testing is claimed to reveal how quickly the body accumulates aging damage.
