Interpretive Data:

Vitamin E concentrations within the healthy reference population range usually indicate adequate Vitamin A stores.

The rare occurrence of low Vitamin A levels might correlate with potential deficiency and investigation of potential fat malabsorptions should be considered.

Conversely, Vitamin E concentrations significantly above the upper healthy reference population range might indicate that Vitamin E intake exceeds the tolerable upper daily intake level(s).
