Things that may affect the test results


There are numerous things that may influence the results of one or several biomarkers. For this reason, we have gathered a few tips to help you get the most out of your test and make tracking of biomarkers more accurate over time.


Time of day


Several biomarkers, including testosterone and cortisol fluctuate daily, peaking in the morning and diminishing throughout the day. It is therefore important to have your blood tested as early as possible in the morning. To further remove possible confounding factors, we advise you to get tested around the same time to better track and monitor possible trends.

Hormonal treatments may affect test results over a long period of time even after finishing the course of treatment. 


Vitamins and supplements may affect the test results in various ways.


Food and Drinks


Biomarkers including Glucose, LDL, Triglycerides and C-peptide are very sensitive to food and beverage intake. If you haven’t refrained from it for at least 10-12 hours, test results will be affected. 


Fat-rich foods may affect results even if taken several days prior to testing.


Alcohol has the ability to affect levels of fats, glucose and liver function biomarkers in a blood test. Refrain from alcohol consumption several days prior to testing to make sure it doesn’t affect your results. 


Physical activity


Physical exercise causes several changes in your body including blood. Thus having the ability to influence your test results. Refrain from strenuous physical activity the day before you get tested and make sure you have enough time to relax once you arrive at the testing site.
