Study start date: December 31, 1996

Actual date on which the first participant was enrolled.

This protocol is designed for screening of subjects before a decision can be made as to their eligibility for one of the active National Heart, Lung, and Blood Institute (NHLBI) research protocols. Its purpose is to allow detailed investigation into the hematologic or oncologic problems of these subjects, and the status of other organ systems that would determine their ability to safely tolerate specific aspects of active research protocols. It allows investigation as to whether a donor is HLA matched, fit to receive G-CSF, and fit to undergo apheresis and therefore eligible to participate as a donor on a bone marrow transplant protocol. It also allows the investigation as to whether subjects are eligible for participation as normal volunteer based on protocol eligibility criteria that requires generally good health status by history or physical exam findings, or laboratory assessments. After completion of this screening process, the subject will either be offered a chance to participate in an active research protocol, or if no appropriate protocol is identified, subjects with hematologic or oncologic disease will have recommendations for other treatment options relayed to the primary or referring physician. Primary objective is to determine subject eligibility for participation on NHLBI protocols. Primary endpoint is the results of clinical, imaging and laboratory assessments.
