We ask you to identify as one of the two binary genders to be able to provide you with the most accurate blood results. Based on biological differences, medical reference values and scientific-research based recommendations recognise sex a either male or female. Since our analysis and scoring system is based on these medical recommendations and studies, when you choose one of the two sexes, we calibrate your results accordingly.
