To determine the corrected reticulocyte percentage, it is essential to adjust the observed reticulocyte percentage based on the patient's hematocrit (HCT) in relation to a normal HCT. This adjustment helps accurately assess the bone marrow's response to anemia or other underlying conditions.

The formula for calculating the corrected reticulocyte percentage is as follows:

Corrected Reticulocyte Percentage = (Reticulocyte Percentage × Patient HCT) / Normal HCT

In this case, the provided HCT of the patient is 30%, and the normal HCT is 45%. If the initial (observed) reticulocyte percentage were, for example, 0.67%, the calculation would proceed as follows:

Corrected Reticulocyte Percentage = (0.67 × 30) / 45

= 20.1 / 45

= 0.447 or approximately 0.5%

When the observed reticulocyte percentage is around 1%, the calculation will yield:

Corrected Reticulocyte Percentage = (1 × 30) / 45

= 30 / 45

= 0.666 or approximately 0.67%, which aligns closely with option B when considering rounding
