Blood sample collection options

Finger prick kit (FREE)

All our kits require a finger prick blood sample which is quick and easy to do at home. But if you don't like the idea of squeezing blood out of your finger, here are some other options:

A home visit by a nurse (+£60)

Have a nurse visit you at home to take your blood sample from your vein. The kit will come with everything the nurse needs to do the blood sample collection. Once you've placed your order, we'll be in touch to arrange an appointment.

Visit a clinic (+£45)

You can visit one of our partner clinics to have a nurse take a blood sample from your vein. Select this option at checkout where you can also see which clinics are near you. Once you've placed your order, we'll send you an email to arrange your appointment.

Organise a nurse myself (FREE)

If none of the above options work for you, you can arrange your own medical professional to collect your sample. There is no additional charge for this. Once you've ordered your test, we'll send you everything you and your chosen medical professional will need to collect a sample and post it back to our labs.

You can choose your blood sample collection method in the checkout. Learn more about sample collection.

Info Gold

When to take the test

If you’re having a regular period, collect your sample on day 3 of your menstrual cycle (day 1 being the first day of your period), otherwise take the test at any time. Collect your blood sample within 3 hours of waking.

IMPORTANT: To avoid contamination, use a different hand than the one you applied hormone gel/cream with for your blood sample.

Benefits of Blood Testing for Triathletes

Elevate Your Performance

Our at-home blood test provides a comprehensive overview of your body's key biomarkers, including iron levels, red blood cell count, and hormone balance. These insights help you tailor your training and nutrition strategies to ensure you have the energy, strength, and endurance to excel in each triathlon discipline.

Optimise Recovery and Prevent Injury

Achieving consistent triathlon success is not just about training hard; it's also about allowing your body to recover effectively. Our home blood test assesses your inflammatory markers and stress hormones, helping you identify any imbalances that could lead to overtraining or injuries. By addressing these imbalances, you can ensure proper recovery, preventing injuries that can derail your training plan and hinder your performance.

Harness Your Hormones

Oestradiol plays an important role in women, especially when it comes to training. Overtraining can cause hormone imbalances, leading to irregular periods. This is called RED-S (relative energy deficiency in sport) and can increase the risk of injury. Keeping track of your hormones when training is essential for protecting your health and preventing injury.

Understand Your Nutrition

Nutrition plays a crucial role in fuelling your triathlon performance and supporting recovery. Our at-home blood test measures essential nutrients like vitamin D, iron, and B12, providing a clear picture of any nutritional deficiencies that may be impacting your performance. With this knowledge, you can make informed dietary adjustments to ensure you're getting the optimal nutrients your body needs to thrive in the triathlon arena.

Tracking Your Progress

Tracking biomarkers every few months can help you see the impact any changes to your training, diet, recovery or lifestyle have on your health, fitness and performance. 75% of Edge customers improved their cortisol and CRP levels after their first test - key biomarkers related to stress, recovery and inflammation.
