The more information researchers have, the more questions they can answer about chronic diseases like cancer, heart disease and diabetes. That’s why we’re inviting selected participants who were between the ages of 30-74 when they completed the OHS questionnaire to also provide a blood sample. Participation will enhance the data you’ve already given and may allow you to learn something that you did not know about your health.
How do I receive an invitation?
At the moment, we are inviting participants to take part in stages based on age and other demographic factors. There are 2 ways to receive an invitation:
- Selected participants will automatically receive an invitation email and will be prompted to take part when they log in to their OHS personalized home page;
- If you’re not prompted, you can tell us you’re interested by clicking the “Express Interest” button once you’ve logged in. If you are experiencing difficulties or you have questions regarding this option please email us at firstname.lastname@example.org.
Am I eligible to provide a blood sample?
You are eligible if:
- you were between the ages of 30-74 when you completed the OHS questionnaire; and
- you have not already provided a blood sample to the OHS.
For your safety you currently are NOT eligible if:
- you have a blood-clotting disease such as hemophilia;
- have had any procedures performed on both sides of your body that would make you unable to give a blood sample (e.g., lymph nodes removed from your arm or chest, an arteriovenous (A-V) shunt for haemodialysis, etc.); and/or
- you have observed any condition that makes sample collection impossible (e.g., rashes, oedema, open sores, wounds, cast, occluded veins on both arms, etc.).
Providing a blood sample to the OHS (or not providing one) is completely up to you. You’re still an important part of the Study even if you choose to only fill out the questionnaire.
And remember that if you do provide a sample the information collected is for research purposes only – it is not diagnostic and does not replace a visit to your doctor or a healthcare professional.
I’ve been invited! What do I do next?
- If you choose to provide a blood sample you will be asked to complete a short online screening questionnaire that takes about five minutes or less. If you registered for the Study before June 18, 2014 you will also be required to fill in a consent form;
- Once you have completed these steps, you will receive your personalized requisition form, which you can print out and take with you to a local LifeLabs® Medical Laboratory Services location (click here to find a location near you);
Making an appointment with LifeLabs is recommended to reduce wait times. If you cannot print your form, please write down the LID and verification numbers on your form and bring these numbers with you.
- At LifeLabs a technician will draw just a small amount of blood (five tubes or approximately 35 mL or 2.4 tablespoons), of which 2 tubes will be used for immediate blood analysis. The remainder of your sample will be frozen for future research. The collection appointment will likely take 10-20 minutes at a time that is convenient for you. No other tests will be performed during this visit.
LifeLabs is a Canadian company that provides more than 100 million laboratory tests to more than 19 million Canadians each year. OHS has partnered with LifeLabs for the Blood Collection Program because they have expertise in blood collection and they have centres most parts of the province.
