- Assess the bone marrow aspiration site for bleeding or hematoma.
- The client must lie flat for 1–2 hours after the procedure.
- Send the specimen slides to the laboratory immediately.
Client and Family Teaching
- Bone marrow aspiration is very painful but only for a brief moment.
- Results are normally available within 24 hours.
Factors That Affect Results
- Poor bone marrow sample will decrease the amount or quality of the cells, leading to inaccurate interpretation.
- Staining of fresh specimens enhances assessment.
