How Is Complete Blood Cell Examination Done? Can You Be Very Painful

CBC won't hurt. It's just a routine blood draw

Bone marrow examination is divided into

Bone marrow biopsy

Bone marrow puncture

Bone marrow biopsy, for short, is a small cylindrical piece of bone marrow about 0.5 to 1 centimeter long taken with a special needle for pathological examination. The operation method is exactly the same as that of bone marrow biopsy. The material removed keeps the complete bone marrow tissue structure, which can make up for the deficiency of bone marrow puncture.

The amount of bone marrow extracted for bone marrow examination is very small, generally about 0 or 2g, while the average amount of normal bone marrow in human body is about 2600g. The body regenerates a large number of blood cells every day, so bone piercings have no effect on the body.

The operation of bone piercing is simple, local disinfection and anesthesia are performed first, and then the puncture needle is inserted into the bone marrow. The pain is basically not felt except for a little pain at the moment of bone marrow extraction. After the bone marrow is extracted, the patient can get up and move right away

To sum up, don't worry too much. You should know that there are more painful things than bone marrow examination in medical examination, so don't have any psychological burden. Before I did not do gastroscopy, many people said that it was so terrible, but when I saw that the elderly and children had done it, I didn't worry at all.
