Blood may be obtained as a single blood draw, which may be a patient's only collection. Patients may be contacted to provide similar specimens at intervals around every 3-4 months for over 5-10 years (for a total of 40 blood draws). Collections will be restricted by the maximum safe volumes outlined above for both adult and pediatric participants. If being obtained in a clinical setting, clinical care specimens will take precedence over research specimens. If specimens are obtained during the course of clinical care, a safe volume will be determined in conjunction with treating physicians, but will not exceed the above table.
