Blood sugar & metabolism

7 values€59 one-time+€15 as an add-on

How does your body handle sugar? HbA1c gives your average over two to three months, glucose your value at that moment, and the ratio between triglycerides and HDL shows how sensitive you still are to insulin. Together they tell you how smoothly your metabolism runs.
