Why take this blood test?

No two bodies are the same. That’s why you get advice based on your results and personal fitness goals.

Your GP report explains how specific health markers affect your fitness and training — like your hormones and nutrient levels.

If an imbalance affects your training, we help you get back on track with tailored lifestyle advice. And you can treat certain nutrient deficiencies with premium supplements.

What's covered in this blood test?

Free testosterone

Learn more

Overtraining and under-recovery might cause your testosterone levels to drop, affecting your performance. Optimal levels can improve your energy and endurance during workouts.

Vitamin D

Learn more

Vitamin D is essential for maintaining strong bones and muscles. Optimal levels might help prevent injuries, promote muscular performance, and support lower body strength.

Omega-3 and 6

Learn more

Optimal omega-3 and 6 can promote heart rate recovery and reduce delayed onset muscle soreness (DOMS). This is a sore, aching, and painful feeling in your muscles after exercise.

Advanced iron profile

Learn more

A ferritin deficiency can affect your fitness. If you’re an athlete or have periods, you have a higher risk of developing low iron due to sweat and blood loss.

HbA1c (diabetes risk)

Learn more

HbA1c is an important marker of your blood sugar control. Regular exercise helps maintain normal levels. Plus, cardio fitness and normal blood sugar control are closely linked.

Cholesterol (lipid profile)

Learn more

Your body needs cholesterol to make hormones, vitamin D, and bile. Regular exercise promotes optimal HDL cholesterol levels — the type that protects you from heart disease and stroke.

Vitamin B9 (folate)

Learn more

Folate is essential for producing red blood cells — these carry oxygen around your body. Low levels might lead to tiredness, muscle weakness, and shortness of breath.

Is this test suitable for men and women?

Yes. Exercise, diet, and certain medical conditions affect men and women differently. It’s important to know the normal ranges for your sex assigned at birth when optimising your fitness. 


When should you do this test?

We recommend doing your blood test before 10 am and fasting (not eating) for 8 hours beforehand. This helps our labs get the most accurate results to check your health.

Avoid vigorous exercise before collecting your sample — this can falsely raise your ferritin levels.

How to collect your sample at home

Learn how to collect your finger-prick blood sample at home by following our instructions. You can access these on the app too. It takes around 30 minutes to complete the process at home.


Will a GP write your report?

Our doctors always review and explain your blood test results. View them in a detailed report on your account dashboard. You'll also get advice to help support your health or manage an existing condition.


How long does it take to get your results?

It might take up to 15 working days to get your results. This is because omega-3 and 6 take longer for our labs to analyse than other health markers.
