A blood tubing set such as an arterial-venous blood tubing set used in hemodialysis is coated with a copolymer having a hydrophobic segment and a hydrophilic segment. For example, the coating can be PEO-PPO-PEO triblock copolymer. The hydrophobic segment attaches to the tubing set, and the hydrophilic segment prevents or reduces unwanted sorption on the blood tubing set.
