- RDR test bioavailability
The Relative Dose Response Test (RDR) was used to assess the bioavailability of vitamin A in a stabilized form in artificially produced rice kernels. The vitamin A proved stable to storage and cooking, and the enriched rice was nontoxic, and had the same sensory characteristics of ordinary rice. The nutrified rice, cooked with sugar and milk, was offered to 83 deprived children as the challenge dose for an RDR test. The children showed positive and negative tests in agreement with their serum retinol levels. The regression of RDR on serum retinol levels was the same as that observed when the conventional RDR test was applied.
