Neutrophils (Absolute) are a valuable biomarker used in longevity research. These white blood cells play a crucial role in the body’s immune response and are often indicative of overall health and inflammation status. Studies have demonstrated a correlation between lower levels of neutrophils and increased longevity, suggesting their potential as a predictive marker for aging-related diseases. Monitoring neutrophil levels can provide valuable insights into an individual’s immune function and overall health, making them a valuable tool in assessing and understanding the aging process. Incorporating neutrophils (Absolute) into longevity research can offer valuable insights into aging and age-related diseases.
