Are you interested in participating in CALIPER?
There are many sick children across Canada and around the world. CALIPER offers one way for you to provide your support. By donating a small blood sample to the CALIPER project, you’ll be helping doctors worldwide diagnose and treat sick children.
Healthy children (determined based on questionnaire responses)
Children who are 0 to 18 years old
Who cannot participate?
Children with a history of chronic illness or metabolic disease
Children who have had an acute illness within the past month
Children who have taken prescribed medication in the past month
What does participation involve?
Schedule a study visit
We’ll arrange an appointment for you at SickKids or at a local school or community organization as part of a CALIPER clinic.
Complete a consent form and health questionnaire
You (and your parent or guardian if you are under 16 years of age) will complete a brief health questionnaire and informed consent form. A member of the CALIPER team will discuss the project with you and answer any questions you may have.Copies of these forms can be viewed at the links below.
CALIPER aims to improve the diagnosis and treatment of children across Canada by determining what is normal and healthy when a child is screened for a disease. Our research is used by doctors in order to compare healthy and normal blood levels to those of their sick patients.
In a case where we find something of concern or abnormal with your child’s blood, we’ll contact your family physician. They’ll be able to share that information with you and choose the appropriate action from there.
This can vary with each child. Some say it feels like a mosquito bite, and others compare it to a pinch. We use a needle called the butterfly needle, which are used on babies being treated in hospitals. It’s the smallest type of needle used for giving blood.
So far, we test for over 185 levels within the blood. This includes hormones, vitamins, minerals, proteins, amino acids and more. These levels ultimately look at serum chemistry, enzymes, proteins, and lipid analytes.
This is an ongoing project that is growing throughout Canada. Since we’re trying to obtain a true representative of the Canadian youth population, continuing to build on our database will only increase the accuracy of our results.
Yes! We’re happy to accommodate any child who wishes to donate. However, their blood may not be used towards our paediatric reference database since it is not “normal”, but may be used in future tests to help other children with illnesses.
Not likely. Most children feel fine after donating, since it is a small amount that’s taken. However, some children may feel anxious, scared and nervous, and sometimes feel faint or nauseous after donating. These symptoms typically last just a few minutes. Generally, children are able to return to their normal daily activities since there is no rest period required after donating.
