This study demonstrates the feasibility of replacing the discard blood sampling method for central vascular access devices with the push-pull method. A comparative, within-subject design was used to evaluate 61 unique, paired blood samples from 1 adult outpatient oncology clinic. A 21-measure laboratory panel was conducted on each of the paired samples. Interpretation showed a small mean bias and excellent agreement between the methods. Blood samples obtained using the push-pull method were within clinically acceptable ranges. No hemolysis was noted by laboratory evaluation of 59 samples.
