Special instructions

This test must be taken between 8am and 10am. If you are tracking your results over time then it is vital that you always have your blood taken at the same time. Fast 8 - 10 hrs prior to sample being taken. Active B12 levels can be affected by use of vitamin B12 supplements. If you are taking an oral supplement then we recommend not taking it for one week prior to the test to ensure an accurate measure of your B12 levels. If vitamin B12 is being prescribed to you by your doctor then you should discuss with them how long to omit B12 supplements for.
This advanced profile for endurance athletes covers all the bases, looking at markers which can help identify overtraining and injury as well as those that could cause lack of energy and motivation. This test is for runners, triathletes and cyclists as well as anyone undertaking an endurance challenge which requires them to be on top of their game. Use this test to establish your pre-training baseline and then track changes as your training load increases.

One of the most important tests for endurance athletes is a full blood count which looks in detail at red blood cells and their ability to transport oxygen around the body. This profile includes a full blood count as well as tests for inflammation and muscle damage, cholesterol for cardiovascular risk, hormones which can be affected by training such as testosterone, oestradiol and cortisol as well as markers for fatigue such as a full iron profile and vitamin B12.

Although this test can be taken as a snap-shot on a single day, it is designed to be tracked over time so that you can learn about what works for you.
