Instructions for Families


Fasting. If your physician has ordered a fasting test, be sure the patient having the blood draw does not to eat before the test. Your doctor will tell you how long you must be fasting before the test and whether certain liquids are allowable. If a blood test is timed before or after a dose of a medication, be sure to make note of the most recent doses of the medication.        

Written prescription must include:

Tests ordered from some Children’s Hospital of Philadelphia Specialty clinics will be marked off on the test list called a “tick sheet”. You may be asked to bring this to the phlebotomy station. In other locations tests may be ordered completely within the computer system, with no paperwork.


If you are coming to The Children’s Hospital of Philadelphia for a blood draw only, without seeing a physician or nurse, you must first go to the PARC office on 3 Main to register.

Support for Patients

Child life

Upon request, we can call a child life specialist to provide age appropriate explanation, education, comfort, distraction, relaxation, or coaching to help a child through the phlebotomy procedure.

A cartoon presentation to help younger children prepare for having blood drawn is available on our web site for kids, Kids Health Galaxy.


Live interpreter services or language line can be arranged to assist families with no or limited English.

Special Needs

Our staff has extensive experience with blood drawing for children with special needs, physical handicaps, behavioral problems, and dependency on medical devices such as ventilators, wheelchairs and other mobility devices.

Restraint Policy

Understanding, psychological support and “talking them through it” are our first approaches to patients who may not cooperate with blood drawing. We instruct parents and caregivers in holding their children for procedures.  Phlebotomy staff can provide limited gentle holding of patients to facilitate rapid and safe specimen collection. We do not use physical restraints.


When necessary, the phlebotomy service will perform blood drawing in the CHOP Sedation unit. Scheduling of waking sedation must be arranged by your physician through the sedation unit, at (267) 425-7300.
