Table 2.
The summary table presents the percent change in biotin tolerance between the old reagent (OR) and the new reagent (NR) after biotin spike-in or depletion. Biotin was added to each sample, and half of the biotin-spiked samples underwent biotin depletion. Both biotin-spiked and biotin-depleted samples were then tested with either the old or new reagents to evaluate their biotin tolerance.
