How long does it take to get the bone marrow biopsy results?

Less than 1 week: The general results from a bone marrow biopsy are usually available in less than 1 week. This will depend on the lab/pathologists reviewing the bone marrow and usually it is just 2-4 days. However some special tests may be done on the specimen that can take additional time. Also, molecular and cytogenetic (chromosome) tests can take longer.

Depends: It depends on the expected diagnosis. A metastatic tumor may be detected in three days or so. Workup of a hematologic disorder often requires multiple tests and may take a week or longer.
