Blood Volume Calculator

The total blood volume calculator here is based on recognized estimation formulas for blood volume in healthy, adult persons.

For Athletes

Athletes will almost always reach much higher blood volume as their volume expands during training. Hence, the actual measurement of total blood volume using the Detalo devices is of great importance to track the effects of their exercise efforts. The total blood volume calculator can be used to establish a baseline and compare to normal healthy adults.

For Patients

The blood volume is also known as the intravascular volume and that refers to the volume of blood in a patient’s circulatory system. A great number of health conditions and sicknesses affect the intravascular blood volume in unpredictable ways. The intravascular volume calculation and estimation are extremely imprecise and the medical doctor is left guessing or estimating in other ways. The use of quantitative measurements is of high importance in these situations and has proven to increase the positive outcomes of treatments in many situations. Research indicates that the use of a standard blood volume calculator can be highly misleading for a large number of patients with circurlatory disorders.


This blood volume calculator is provided “as is” and cannot be used to diagnose nor treat any disease or illness. The calculator provides an estimated value of blood volume with healthy and normal adults. Actual blood volumes will almost always differ from the estimated values. The estimation of blood volumes for any kind of health condition is impossible.
