What is Bone Marrow Aspirate?
Bone marrow aspirate is a procedure utilized to extract a small amount of bone marrow fluid and cells through a needle. This sample is then examined under a microscope for various diagnostic purposes. The bone marrow, a spongy tissue found inside bones, is crucial for the production of blood cells.
How is Bone Marrow Aspirate Collected?
The procedure typically involves inserting a needle into the posterior iliac crest of the pelvic bone. Local anesthesia is applied to minimize discomfort. Once the needle is in place, a syringe is used to aspirate the marrow fluid and cells.
What are the Risks and Complications?
Though generally safe, bone marrow aspiration carries some risks. These include bleeding, infection, and discomfort at the puncture site. However, complications are relatively rare when performed by experienced clinicians.
How is the Sample Processed?
Once collected, the bone marrow aspirate is spread on glass slides and stained. The slides are then examined under a microscope by a histologist or pathologist, who evaluates the cells' morphology and counts different cell types.
Conclusion
Bone marrow aspirate is a pivotal diagnostic tool in histology, providing valuable insights into hematologic and systemic diseases. Through careful collection, processing, and analysis, it aids in the diagnosis, monitoring, and treatment of various conditions, contributing significantly to patient care.
