The "not showing in the test results" could be insulin "resistance"? Enough glucose in the blood which is unable to enter the cells?
Im in the same boat. Wait for chromium to arrive to see if it helps.
The most frequent causes for insulin resistance ive read: cortisol too high too long time, too much toxins inside for too long time, lack of chromium. Some added lack of manganese or even D3? Who knows...
