1. Where should I go to have my blood drawn?

Study participants typically have their blood drawn for the study by taking the pre-assembled blood collection kit to their doctor or usual health care provider. Some participants have arranged to have their blood drawn at their place of employment (if working in a hospital or clinic).

If you do not have a regular physician, or if you have difficulty arranging to have your blood drawn at your own clinic, please contact the study office at 1-800-447-6466. Our staff has worked with many clinics across the country to answer questions or provide more information about the study. We also may locate a facility in your area where you can go to have your blood drawn for the study. You can decide what is most convenient for you.

2. How soon do I need to have my blood drawn?

We ask that participants have their blood drawn within a month of receiving the blood collection kit. If you will be visiting your doctor or health care provider for another reason in the next few weeks, such as an appointment for routine, preventative, or follow-up care, the blood sample can be drawn at the same time as that appointment.

Don't worry if you don't have a scheduled doctor's appointment. Often, doctors or clinics are willing to draw the blood sample without a scheduled appointment if you contact them in advance and explain that you are participating in a research study. Clinics are used to having patients come in for lab work without seeing a physician. All the information needed to draw, pack and ship the blood sample is included in the blood collection kit. Please let us know if we can help in any way.

3. Who pays for the blood draw?

There is no charge to you or your insurance to have your blood drawn on this study. Often health care providers are willing to draw the blood sample for no charge when you are participating in a research study. However, if there is a charge for drawing your blood, the charge will be paid by the study. When there is a blood drawing charge, we ask that your health care provider contact our study office prior to, or at the time of, the blood draw to make arrangements for payment.

4. Do I have to participate

Your participation is voluntary. We do encourage the participation of all individuals selected for the study. The results of the study will benefit radiologic technologists in the future and to add to the general body of information about genetic predispositions to certain types of cancer and low dose radiation exposure.

5. How much blood will you draw?

The amount of blood requested is about 4 teaspoons. This small amount of blood is very safe to donate and is adequate for the research that will be done in this study.

6. Under what conditions should I not have my blood drawn?

Please discuss any specific health concerns with your own personal physician.

  • If you have an infectious disease (i.e., hepatitis, AIDS, etc.) you should not participate in the blood collection effort.

7. Will I get results of my blood tests?

The tests we will conduct are for research purposes only and study participants will not receive individual results. For most of these tests, we will not know how to interpret individual results in terms of risks or benefits. Also, the way the samples are collected and processed are different from the way a clinical sample is handled, and the testing may not be appropriate for making individual medical decisions. We will provide summary findings through periodic newsletters or study updates and on this website.
