What formula is used to calculate the percentage of remaining recipient cells after a transplant?

To determine the percentage of remaining recipient cells after a transplant, the appropriate formula is based on the total number of cells present, which includes both recipient cells and donor cells.

The formula for calculating the percentage of recipient cells is articulated as the number of recipient cells (R) divided by the sum of recipient cells and donor cells (R + D). This gives a representation of what fraction of the total cell count is made up of recipient cells, thereby yielding the percentage of these cells in relation to the total. Thus, the expression can be framed as % of recipient cells = R/(R+D).

Using this calculation, researchers can accurately assess the proportion of recipient cells still present following a transplant procedure, which is crucial for understanding the efficacy of the transplant and the subsequent immune response. This metric helps in evaluating graft acceptance or rejection and monitoring the overall success of the transplant procedure.

The other provided formulas either incorrectly represent the contributions of donor cells or misdefine the overall structure needed to calculate the remaining recipient cells, making them inappropriate for this question.
