How old are you on the inside?

"A man is as old as his artery" Thomas Sydenham, a 17th century physician.

How does Bio Clip work?

Bio Clip works by measuring a person's pulse waves which are detected via an infrared light emitted by the Bio Clip when it is attached to a finger. Infrared light can be used in this way because of the light absorbing characteristics of oxyhaemoglobin (HbO2) that is found in arterial blood. The amount of light is directly proportional to the volume of blood in the finger pulse. With the skin being so richly perfused (full of the blood that is supplying oxygen), it is relatively easy to detect the pulsatile component of the cardiac cycle. Bio Clip takes a short recording lasting 10-30 seconds and from this, it calculates your average pulse. Bio Clip then produces a typical pulse wave form and automatically derives your Stiffness Index (SI) and your Reflection Index (RI).

How does Bio Clip measure Bio-vascular Age?

Using the results, and in particular those relating to arterial stiffness, the Bio Clip system is able to calculate a bio-vascular age. Bio-vascular age is the term given to describe the comparative age of a person's arteries - in other words are your arteries older or younger than your actual age?

Over 2000 patients between the ages of 18 and 75 were tested at St. Thomas' hospital in London. Those results are encoded onto the BioClip software, this means that your stiffness index (SI) result is compared to that database. The results not only output your comparative vascular/ biological age, but they also show between which age groups those results would be expected; for example; 64 (58-70) It is through this method that it is easy to track your results and what changes mean to the average in the population. After all, you may not remember your stiffness index reading in metres per second, but you will remember your biological age!

How to prepare for the test?

Do not eat or drink anything a couple of hours beforehand, in particular caffeine laced sodas and coffee should be avoided. Bio-Clip testing should be performed when a person is breathing normally and not when they have just finished a cardio workout. It's advisable to avoid excessive exercise in the 24 hours prior to testing.

The good news is that your results can always be improved through lifestyle, diet, exercise and natural supplements. The BioClip gives you the incentive to make those changes, stick to your wellness program and ensure that what you are doing is in fact making benefits for your health and fitness.


The Bio-Clip Plus test is not a medical diagnostic tool. A Bio-Clip Plus test provides screening information important to the individual's current state of fitness and wellness and it does not replace the advice of a licensed physician.
