🩸 Biological Age Calculator from Blood Test

According to the scientific PhenoAge formula (Levine 2018). Enter 9 values from a standard blood test and discover your biological age, a more accurate marker than age based on lifestyle alone.

💡 This tool complements the age calculator based on lifestyle. Here you enter numbers from a blood test you have already taken, and receive an estimated clinical biological age. Not all values from a single test are needed simultaneously, but all are required for the calculation. We do not store your data.
Blood protein, a marker for liver function and nutrition. Normal range approximately 3.5 to 5.0.
Mark for kidney function. Normal range approximately 0.6 to 1.3.
Fasting blood sugar. Normal range approximately 70 to 99.
Inflammation marker. Lower is better, preferably below 1.
Immune system cells. Normal range approximately 4 to 11.
Percentage of a certain type of white blood cells. Normal range approximately 20 to 40.
Average size of a red blood cell. Normal range approximately 80 to 100.
Variations in red blood cell size. Normal range approximately 11.5 to 14.5.
Enzyme, marker for liver and bone. Normal range approximately 40 to 130.

⚕️ Educational tool only, not a medical diagnosis. The PhenoAge formula is a population-based statistical estimate and does not replace test interpretation by a physician. Do not make medical decisions based on the result. Always consult a doctor regarding your blood tests.
