Does increased 2,3-DPG concentration shift the oxygen dissociation curve to the left or right?

Answer
You are correct.
An increased concentration of 2,3-DPG (2,3-diphosphoglycerate) decreases hemoglobin's affinity for oxygen. This causes the oxygen dissociation curve to shift to the right, facilitating the release of oxygen to the tissues.
Therefore, the statement "shifts the oxygen dissociation curve to the left" is incorrect. It should be:
This leads to increased concentration of 2,3 DPG and shifts the oxygen dissociation curve to the right, and includes low oxygen affinity.
