Conventional methods are considered as difficult to effectively smear

-Bloody effusion -Mucous effusion -Clear effusion

Conventional methods are sometimes caus-ing false negative and false positive.

Bloody smear Dirty background& overlaping

Main purpose of LBC technology

-Thin smear -Clean background -Less degeneration than conventional method

use specially-designated equipment for smear. specially-designated filtering membrane. specially-designated reagent solution.

Process for specimen of effusion

• Step 1. Sampling from patient by physician

• Step 2. Transfer to cytopathologic laboratory -Effusion derived from patients should immediately be transferred to cytology rooms to prevent cellular degeneration -Cellular degeneration starts 30 minutes after sampling of effusion -More delay means increased intensity of degeneration -We should prepare the sample immediately to block cellular degeneration in labs

Step 3. Classify specimen according to feature of effusion for pre-treatment

Page 9: An Analysis on Cytology Diagnoses  of the Effusion  using LBC Technology

Step 4. Treatment of specimen according to feature of effusion

1. In case of non-bloody effusion & clear effusion (generally common method : non-treatment of background) - after centrifuge at 1500~2500 rpm / 5 mins

- move sediment to preserve solution

- smear cells on slide by divice

- staining

9

Page 10: An Analysis on Cytology Diagnoses  of the Effusion  using LBC Technology

2. In case of bloody effusion

- centrifuge

- add “hemolysin” solution for hemolysis

- centrifuge - move sediment to preserve solution

- smear cells on slide by divice

- staining

10

3. In case of mucous effusion - centrifuge

- add “mucosin” solution for discarding mucus

- moving sediment to preserve solution

- smearing cells on slide by device

- pap staining

In conclusion

1. Slide smear using the LBC technologies have advantages com-pared to two conventional methods. -The strengths follow: Eliminating backgrounds around diagnostic cells effectively makes easy microscopic work. -As LBC technology enables to manufacture thin smear, a deep and thorough reviews of morphological features in diagnostic cells are guaranteed. -As the LBC technology enables to allow samples to have proper substance of background, identification for details of malignant cells like mucus producing adenocarcinoma and signet ring cell type adenocarcinoma is useful.

2. Based on different status of specimen, -the LBC technology could produce a series of slides. Meanwhile, re-examination and special stain are also posible. -As diagnostic cells exit in a slide by forming groups, it's also possible to find the origin of malignant details in metastasis.
