About Endurance fit

What is the Endurance Fit test?

Endurance Fit is a comprehensive test of your fitness, nutrition and recovery. Your blood contains an array of markers related to your fitness, including muscle mass (testosterone), stress and fatigue (cortisol), anaemia (iron and red blood cells), general health (thyroid function), nutrition (vitamins and minerals) and immune function. Using this test to assess and monitor your physical state enables you to get the most out of training to achieve your health and fitness goals.  

Why take the test?

This test provides information on a variety of biological markers including hormones, iron levels, inflammation, and tracking of general health such as kidney, liver and thyroid function. The test can be used to track changes over time to ensure peak health and fitness. This test is similar to the Advanced Fit test but also investigates thyroid function, clotting ability, and white and red blood cell properties.
