Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The purpose of this study is to find out if doing chimerism testing earlier than the traditional approach is better for patient outcomes (about 14 days after transplantation rather than 30+ days). Information gained from this study can be used to help prevent some post-transplant complications such as graft loss, graft-versus-host disease, or even relapse for future patients.
Also, the researchers hope to learn more about chimerism testing of cells of patients with haploidentical donors (donors who are only a "half-match" - such as a parent or child of the recipient), because there have not been many chimerism analysis studies done in this population.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Allogeneic Stem-Cell Transplant Recipients
1. At day +14/15-post transplant - lineage-specific chimerism analysis will be performed on a peripheral blood sample drawn from the patient.
2. At day +30-post transplant, most participants will be in the outpatient setting and would undergo chimerism evaluation as part of the standard of care for transplant patients.
Chimerism Evaluation
Blood collection for chimerism evaluation will be performed on days +14/15-post transplant and +30-post transplant for each study participant.
Interventions

Chimerism Evaluation
Blood collection for chimerism evaluation will be performed on days +14/15-post transplant and +30-post transplant for each study participant.
