Video description: epigenetic clocks, DNA methylation and biological age claims
The description attributes to Ryan Smith, founder of TruDiagnostic, claims that DNA methylation clocks can estimate biological age from a single drop of blood, predict mortality with 92% accuracy within five years and track aging changes in as little as six months. These are creator claims in a video description, not reviewed findings. [1]

The key findings
The description says DNA methylation clocks analyze epigenetic patterns at 29 million genome locations and are contrasted with static genetic tests. [1]
The description attributes to TruDiagnostic's algorithms a 92% accuracy for predicting mortality within five years and tracking aging changes in as little as six months. [1]
The description calls aging the number one risk factor for chronic disease, 10 times more significant than smoking or obesity, and cites a database of over 120,000 patients. [1]

Described methylation clocks and 29 million sites
According to the description, Smith explains DNA methylation clocks that analyze epigenetic patterns at 29 million locations across the genome. The description contrasts these with static genetic tests such as those from 23andMe, saying epigenetics shows which genes are turned on or off in real time and reflects sleep quality, stress, nutrition and environmental exposures. The description attributes the algorithms to development with Harvard and Duke University.

Described mortality prediction and six-month tracking
The description states that TruDiagnostic's algorithms can predict mortality with 92% accuracy within five years and track biological aging changes in as little as six months. It also says the clocks can measure biological aging from a single drop of blood and provide over 100 biomarkers. The description presents the Rejuvenation Olympics, a competitive leaderboard with biohackers such as Brian Johnson, as examples of how interventions are said to affect biological aging rates.

Described risk ranking and database size
The description says aging is the number one risk factor for chronic disease and is described as 10 times more significant than smoking or obesity. It also cites a TruDiagnostic database of over 120,000 patients and 45 or more published studies. The description frames epigenetic testing as an essential part of a biohacking strategy and says the session offers practical guidance for longevity optimization.
