Interesting question: Optimal is a interesting question. First it is important to understand where "normal" is derived. "Normal" ranges for each lab is a statistical number that tell where a population of "normal" people results run. So your numbers run within the "normal" (reference) range for most laboratories. Are your results "optimal" is a question that is thus difficult to answer!
