You are asked to test the osmotic fragility of a patient's red blood cells (RBCs). After calculating the percent lysis, you plot the results. The patient's lysis curve is significantly shifted to the left of the normal curve. What does this indicate?
A) The patient's RBCs have a high osmotic fragility, consistent with the presence of spherocytes.
B) The patient's RBCs have a high osmotic fragility, consistent with the presence of target cells.
C) The patient's RBCs have a low osmotic fragility, consistent with the presence of spherocytes.
D) The patient's RBCs have a low osmotic fragility, consistent with the presence of target cells.
