What is liquid based cytology technique

What are the solutions for liquid-based cytology?
In recent years, LBC has been widely used for cytology, and there are several types of LBC preservative solutions.
The components of LBC preservative solutions include methanol, ethanol, and formaldehyde in various proportions, and some solutions contain hemolytic agents or substances that prevent protein aggregation..
What is a liquid-based cytology test?
Liquid-based cytology (LBC) is a new method of preparing cervical samples for cytological examination.
Unlike the conventional 'smear' preparation, it involves making a suspension of cells from the sample and this is used to produce a thin layer of cells on a slide..
What is liquid-based cytology in FNAC?
Liquid-based cytology (LBC) as a technique was introduced and tried on Pap smears.
It received the Food and Drug Association (FDA) approval in 1996. [1] Thereafter, this technique was performed for non-gynecological cytology, including conventional fine needle aspiration cytology (FNAC), guided FNAC and fluid cytology..
What is the AAFP technique for Pap smear?
Evidence-Based Answer
The combination of an extended-tip spatula with an endocervical brush (Cytobrush) is the most effective method for obtaining cervical cells.
Detection of endocervical cells is a good indication of adequate smears and detection of disease..
What is the SurePath method of liquid-based cytology?
Increased abnormal cell detection
Collect.
Collect the cervical sample with the Rovers \xae Cervex-Brush \xae device. * Drop.
Drop the detachable head of the device into the BD SurePath collection vial.
All brush heads must be placed into the larger chamber of the vial.Send.
Place the cap on the vial, and tighten it. Read..
Additional advantages of the ThinPrep include being able to perform human papillomavirus (HPV) testing on the liquid.
This is the preferred triage strategy for atypical squamous cells of undetermined significance (ASCUS) Pap smears (SOR: A, based on a large randomized, controlled trial).
LBC can be a better alternative to conventional smear because of lower rate of unsatisfactory smears.
Furthermore, residual LBC sample is available to perform HPV DNA testing.
LBC with concomitant HPV testing can prove to be more effective in high-resource setting.

Liquid-based cytology is a technique that enables cells to be suspended in liquid medium and spread in monolayer and thus better morphological assessment is possible. It includes the preparation and evaluation of cells collected in a liquid fixative.

How do liquid based smears improve Cellular Visualization?

Decrease in obscuring factors.
The liquid-based processes generally improve cellular visualization via decreases in physiologic obscuring factors such as:

blood or inflammation

The cells in conventional smears may be obscured, leading to unsatisfactory or limited specimens when such factors are present.

What does LBC mean in cytology?

In cytology using the LBC method, the background is generally clearer, the cells are evenly distributed, and the cells tend to have slightly enlarged cytoplasm and nuclei and slightly fainter nuclear chromatin.
However, it should always be kept in mind that there is a frequency of false negatives and false positives in cytology.

Which cytology test should be performed if a sample is undiluted?

From undiluted sample, obtain liquid-based cytology to evaluate cellularity If both undiluted and diluted samples, submit undiluted for cultures and diluted for cell block and special stains Herpes zoster virus (HZV), herpes simplex virus 1 (HSV1), and HSV2, CMV, Toxoplasma, or other specific for clinical suspicion (EBV, etc.) .
