Phlebotomy Services are committed to providing excellence in patient care, in partnership with other CHOP departments, by providing quality, timeliness and distinction in patient satisfaction. We treat everyone we serve with compassion and kindness. Furthermore, we support research, education and public service programs that enrich the quality of life.

The phlebotomy staff is composed of carefully trained individuals with extensive experience drawing blood from children of all ages, including infants and children with multiple medical needs whose veins may be “difficult.” The staff strives to obtain specimens with the minimum discomfort and anxiety for the patient and family, and with the minimum volume of blood taken to perform the necessary tests.

Critical aspects of the quality of phlebotomy services are monitored carefully. These include accuracy in specimen labeling, accuracy in test ordering, and specimen integrity. Important aspects of customer service are also monitored, such as waiting time at outpatient stations.
