Dr. Börgel performed blood tests for me because of a vegan diet and an existing metabolic disorder. She seems very nice, competent and confident, answered all my questions and has put together the perfect combination of blood tests for me. She explained the results, including the complicated correlations, in a very understandable way. Furthermore, I received a product-flexible income plan for the supplements. All in all, just as one would wish. I will have my blood values checked here regularly in the future.
