Key points

  • Estimates biological age with the Phenotypic Age (PhenoAge) method published by Levine and colleagues in 2018
  • Uses your age and nine routine blood markers: white cell count, lymphocytes, mean cell volume, red cell distribution width, albumin, alkaline phosphatase, creatinine, glucose and hs-CRP
  • Takes UK units as they appear on your report: white cells and lymphocytes as counts in 10^9/L, creatinine in umol/L, glucose in mmol/L and hs-CRP in mg/L
  • Use results from one fasting blood draw, taken when you are well. Recent illness, hard training or dehydration can shift several of these markers
  • Longevity Gold measures all nine markers this calculator uses in one blood draw. Longevity Silver measures eight of them, without glucose
  • The method was developed from United States health survey data on adults aged 20 and over, so it describes populations better than any one person
  • This is a calculated estimate, not a diagnosis, and it does not predict how long you will live. A healthcare professional can interpret your results in context
