Measure instead of guessing

Training for a race, or just want more energy in everyday life? The numbers give you a starting point - and when you measure again, you can see whether what you are doing works.

The Danish Health Authority recommends that adults are physically active for at least 30 minutes every day and do muscle-strengthening activities at least twice a week. A little is better than nothing.

Biohacking and longevity - without the hype

Many people talk about biohacking and longevity. We stick to what can be measured and explained: fitness level, blood pressure, blood sugar, cholesterol and blood tests with an established meaning. We do not promise optimisation - we give you the numbers and explain what they mean.

What can make sense to measure

Fitness

Fitness level (VO2 max)

Shows how well your lungs, heart and muscles take up and use oxygen. You get a ranking for your age and sex.

About the fitness test →

Iron

Ferritin

Shows your body's iron stores. Relevant with heavy periods or a plant-based diet.

Iron deficiency - symptoms and blood test (in Danish) →

Vitamins

Vitamin D

Low vitamin D is common in the winter months. A measurement shows your actual level.

Hormones

Testosterone

Falls during the day, so the test makes most sense in the morning. One low result is not a diagnosis.

Sex hormones and timing →

Muscles

Creatine kinase (CK)

A muscle enzyme that rises after hard training. Ideally avoid hard training for 2-3 days before the test.

Stress

Cortisol

The body's stress hormone. We recommend that the sample is taken in the morning, ideally before 10.00.

Good to know

If you get chest pain, faint or suddenly become short of breath during training, stop and contact a doctor straight away - call 112 if symptoms are acute.

We do not make diagnoses or carry out investigations. If a value is outside the normal range, we recommend that you follow up with your own GP. We do not write training programmes, but we are happy to explain what your numbers mean.

Frequently asked questions

No. NurseCare measures your fitness level lying down with a small sensor on your breastbone. The measurement itself takes 45 seconds, and the whole test including a review takes about 10 minutes.

It depends on what you want to know. Many start with the basic blood test package, which measures haemoglobin, ferritin, B12, long-term blood sugar and cholesterol, among others. If you want to follow specific markers such as testosterone, creatine kinase (CK) or cortisol, you can build your own package.

Before a creatine kinase (CK) test, ideally avoid hard training for 2-3 days, because training makes the value rise. We recommend taking cortisol in the morning, ideally before 10.00. You can always book whenever it suits you - we note it so the result can be assessed correctly.

We offer measurements with an established meaning - fitness level, blood pressure, blood sugar, cholesterol and blood tests - and explain your numbers. We do not promise optimisation and do not recommend supplements or treatment.

No. We measure and explain your numbers. A training programme is a matter for a coach or physiotherapist - feel free to bring your results.
