The price of lymph node aspiration biopsy is around 500-1000 RMB. If a patient has swollen lymph nodes all over the body, but cannot make further judgment on the benignity or malignancy of the disease, lymph node aspiration can be done to take a small amount of tissue for pathological examination to make further judgment on the benignity or malignancy of the disease. The lymph nodes can be punctured under ultrasound guidance. First, a large lymph node should be taken, then the surface should be disinfected with iodophor, and the lymph node should be punctured with a fine needle at multiple points inside the lymph node under ultrasound guidance to obtain tissue for examination. The subsequent price may vary depending on the pathological examination items. If the pathological examination is difficult, immunohistochemistry may also be required, so the price may be more than 1000 RMB.
