How are bone marrow tests performed in the hospital?

1. Selection of puncture site

① Anterior superior iliac spine: The puncture point is usually 1 to 2 cm behind and above the anterior superior iliac spine, where the bone surface is flat, easy to fix, and the operation is convenient and safe; ② Anterior and posterior superior spine: located on both sides of the sacral vertebra and above the buttocks (3) Manubrium: This place is rich in bone marrow. When the puncture of the above-mentioned parts fails, the manubrium can be punctured, but the bone here is thin, and there are atria and large blood vessels behind, so the danger of penetration is strictly prevented. Use less; ④ Spinous process of lumbar vertebra: It is located at the prominence of spinous process of lumbar vertebra and is rarely used.
