Withdrawing as this is not a clinical trial

The collection of Blood and/or Bone Marrow from patients with blood disorders, blood cell malignancies and associated conditions will serve as a convenient and comprehensive source of tissue to give us further information about the differences between normal blood cells and blood cells of affected individuals. This will be an invaluable asset for understanding the biology of blood disorders. The collected samples will be used by investigators for studies including immunology, molecular biology and genetics to name a few.

Inclusion Criteria:

• Selected patients over the age of 18 with hematologic malignancies or other blood disorders (leukemia, myeloproliferative disorders, lymphoma, other malignancies involving the bone marrow or patients with unexplained alterations in their complete blood count).

Patients who are scheduled to undergo a bone marrow aspirate and/or phlebotomy for other clinical indications will be asked to participate. They will be asked to donate an additional small aliquot of bone marrow and/or blood during the course of their already scheduled bone marrow aspiration or phlebotomy.

Exclusion Criteria:

• Patients with pre-existing medical conditions that might be exacerbated by the procedure of obtaining bone marrow or blood
• Patients who are allergic to Lidocaine, which is used as a local anesthetic, and who cannot receive a suitable substitute anesthetic.
• Patients who have a bleeding diathesis which might pose a problem with marrow aspiration.
• Patients unable to give informed consent.
• Pregnant patients

Patients over the age of 18 with blood and/or bone disorders (leukemia, myeloproliferative disorders, lymphoma etc.) with alterations of their blood counts.
