I. General Requirement
These procedures support the university’s efforts to protect human subjects and UNCW researchers while minimizing institutional risk in conducting blood draws for research purposes.
II. Scope
This SOP pertains to all human subjects research projects that involve blood draws. These procedures apply to any blood draws occurring on the UNCW campus or conducted by UNCW’s staff, students, and faculty.
Please note, if the research blood draws will occur at off-site locations that are not owned or leased by UNCW (such as hospitals or other healthcare facilities or private physician offices) with their own venipuncture or equivalent policy, then that site’s policy supersedes these procedures. If UNCW faculty, staff, or students conduct blood draws at those sites, they must follow the site’s policy. If the site is contracted by a UNCW principal investigator (PI) to conduct blood draws for research, the off-site personnel must follow the site’s policy.
III. Definitions
All terms used in these procedures have the same meaning set forth in the policy unless otherwise defined in these procedures.
A. Children—as defined in the HHS regulations, "persons who have not attained the legal age for consent to treatments or procedures involved in the research, under the applicable law of the jurisdiction in which the research will be conducted." 45 CFR 46.402(a).
B. Expedited Review—review conducted by the IRB Chair or by one or more qualified reviewers designated by the chairperson from among members of the IRB.
C. Finger stick means a type of blood draw where the finger is pricked with a lancet to obtain a small amount of capillary blood.
D. Intravenous (IV) lines mean a thin tube or cannula that is inserted into a vein, typically to administer drugs, blood, or fluid products directly into the bloodstream.
E. Phlebotomy/venipuncture means a type of blood draw in which a needle is used to take blood from a vein. Multiple tubes may be collected; however, it is considered a single blood draw “stick” and the needle is taken out and a bandage is used.
IV. Blood Draws Qualifying for Expedited Review
A. Expedited Review of Blood Collection
The federal regulations 45 CFR 46.110 and 21 CFR 56.110 allow research activities that present no more than minimal risk to human subjects and involve only procedures listed in an expedited review category may be reviewed by the IRB through the expedited review. Collection of blood samples by finger stick, heel stick, ear stick, or venipuncture is an activity that is included in the Expedited Review Category 2 provided the following requirements are met:
1. The collection is from healthy, nonpregnant adults who weigh at least 110 pounds. For these subjects, the amounts drawn may not exceed 550 ml in an 8-week period, and collection may not occur more frequently than 2 times per week; or
2. The collection is from other adults and children, considering the age, weight, and health of the subjects, the collection procedure, the amount of blood to be collected, and the frequency with which it will be collected. For these subjects, the amount drawn may not exceed the lesser of 50 ml or 3 ml per kg in an 8-week period, and collection may not occur more frequently than 2 times per week. B. All Other Blood Collection
If the criteria for Expedited Category 2 cannot be met, studies involving blood collection will be reviewed by the full board.
V. Blood Draw Considerations
A. Personnel Qualifications
1) All blood draws must be performed by personnel who are proficient in both phlebotomy and safe handling of blood and human tissues.
Examples of appropriate credentials include, but are not limited to:
a. Medical or Nursing license
b. Medical Technologist license or certification
c. Phlebotomist license or certification
d. Advanced EMS certification
2) The PI must justify on the IRB application that the individual(s) who will perform the blood collection will do so within their scope of practice, have appropriate training, and are credentialed appropriately.
A. Volume
Blood samples must not exceed the minimal amount necessary for analysis. This amount must be documented in the IRB application and approved by the IRB. Justification for the amount must comply with federal guidelines and the scope/purpose of the study.
B. Subject Screening
There must be no contraindications for blood withdrawal that would injure the subject or contraindications that would undermine the research goals. The PI or designee must create and submit for approval appropriate screening tools to identify contraindications. The IRB will consider factors, including but not limited to the following, when assessing the risks and benefits of blood collection:
1. Health status of the subject population—a) Blood clotting conditions, b) Receiving chemotherapy, c) Vascular grafts, hematoma
2. Volume of blood the researcher proposes to collect
3. If opportunities exist to collect blood at the same time as a clinical visit
D. Special Informed Consent Requirements
Subjects must be informed through an appropriate informed consent process of the potential risks of blood collection, which may include:
a. Bruising
b. Hematomas
c. Infection at the blood collection site
d. Allergies (e.g., latex, betadine, bandage/tape)
e. Less common risks such as nerve damage or extensive bleeding
VI. Safety Considerations
A. UNCW Environmental Health & Safety Requirements
The PI or designee of the study must upload the completed Bloodborne Pathogen Exposure Control Plan in the Supporting Documents section of the IRB application as documentation of having engaged EH&S.
If a third-party contractor is used to collect blood, the PI must ensure that the contractor has appropriate safety protocols in place and is properly trained and credentialed.
B. Location
When blood draws are conducted on UNCW premises, they must be conducted in an appropriate location inspected by UNCW EH&S before final approval by the IRB:
1. Floors must not be carpeted. If the only option is a carpeted space, plastic or other impervious and cleanable material must be used to cover the carpet.
2. One or more comfortable chairs must be available. Chair covers must be non-porous. If a chair with a nonporous cover is not available, a cleanable and impervious cover must be used on the chair. Chairs must be used for the subject. When research involves the collection of blood mid-exercise, a chair must be available in case the exercise subject becomes light-headed.
3. Space should have a curtain or door for privacy if possible.
4. Space must not be used for eating or drinking.
C. Infection Prevention
Per WHO guidance, proper procedures must be followed to prevent infection:
1. The researcher conducting the blood draw must first wash his/her hands, wrists, and in-between fingers with soap and water or an alcohol rub for at least 30 seconds.
2. Personal Protective Equipment must be available and used. Avoid using latex gloves in case the subject or researcher is allergic to latex.
3. Single-use gloves must be worn during all blood withdrawal procedures. Hands must be washed, and gloves must be changed between subjects.
4. Tourniquets must be single-use or cleaned before the next use.
5. Only single-use/one-hand cap devices must be used for blood withdrawal.
6. Each subject’s skin must be disinfected prior to blood draw.
7. A sharps container must be no more than four (4) feet from where the blood draw is conducted.
8. Work surfaces must be decontaminated/disinfected for the appropriate contact time immediately after work is complete. Suitable disinfectants include: a) A 1:10 dilution of 5.25%-6.15% sodium hypochlorite (i.e., household bleach) for 10 min contact time. NOTE: A dilution of 70% ethanol may be used to remove chlorine residue following disinfection to reduce the wear on metal surfaces; b) An EPA–registered tuberculocidal disinfectant, used for contact time listed on the disinfectant.
9. Blood samples that are to be transported outside the building must be sealed in appropriately labelled, leak-proof primary tubes/flasks/containers and disinfected on the outside before being placed into a durable, leak-proof secondary transport container. A biohazard symbol will be placed on the primary container. The secondary container will be disinfected and secured for transport.
