Resources from multiple studies may be requested via one request form using the above drop down menu.
Describe this request, including a summary of the rationale, main hypothesis and proposed research aims* A brief overview of your research needs.
Specimen requirements
Describe any additional requirements pertaining to the biospecimens themselves, such as anticoagulant used, additives, preservatives, etc.
Participant characteristics
Describe the characteristics of the participants to be searched for available specimens. Criteria might include gender, age, disease status, genotype, etc. Be as specific as possible.
Requested study visit(s), if applicable
Only applicable for studies that have more than one specimen draw point. If any visit is acceptable, please indicate so. Refer to the "Available Biospecimens" tables on each study description page for more information regarding the available visits for each material type. If more than one visit is requested, please indicate if you can accept participants that have specimens available from at least one, but not all of the requested visits.
