Monocytes (Absolute) is a crucial biomarker for assessing longevity. These white blood cells play a key role in the body’s immune response, helping to defend against infections and inflammation. Elevated levels of monocytes have been associated with aging-related diseases such as cardiovascular disease and cancer, making it a valuable marker for predicting health span. Monitoring the absolute count of monocytes can provide valuable insights into an individual’s immune function and overall health status, allowing for early intervention and personalized strategies to support longevity. As part of a comprehensive biomarker panel, tracking monocyte levels can help individuals make informed decisions to optimize their health and longevity.
