How do you process liquid-based cytology?

How do you process liquid-based cytology?

The LBC technique is based on a two-step procedure: (1) the fixation of the FNA material in an alcohol-based solution (methanol or ethanol depending on the technique, discussed later), and (2) the automated processing of the material to obtain a thin layer of representative cells.

What is liquid-based Pap smear?

A Pap test can also show conditions that are not cancer, such as infection or inflammation. In a liquid-based Pap test, the cells are rinsed into a small container of liquid. The cells are then placed onto slides by a special machine and examined under a microscope to see if the cells are abnormal.

How do you collect samples for liquid-based cytology?

Alternative collection method: A plastic spatula and cytobrush may also be used to collect LBC samples. Insert the spatula into the cervical os and rotate 360° with firm pressure. For SurePath: Snap off the head of the spatula (avoid touching the head of the device), and drop into the liquid vial (avoid splashing).

What is the difference between conventional and liquid-based Pap smear?

Conclusion This study indicates that liquid-based cytology does not perform better than conventional Pap tests in terms of relative sensitivity and PPV for detection of cervical cancer precursors. The conventional papanicolaou (Pap) test is considered suboptimal due to false-negative and false-positive test results.

Is Pap smear liquid-based cytology?

Two methods are used for cervical cytology. The first one is the conventional Papanicolaou (PAP) and the second one is liquid-based cytology (LBC).

How do I prepare for a Pap smear?

How you prepare

1. Avoid intercourse, douching, or using any vaginal medicines or spermicidal foams, creams or jellies for two days before having a Pap smear, as these may wash away or obscure abnormal cells.
2. Try not to schedule a Pap smear during your menstrual period.

What is LBC kit?

PAPProcer LBC KIT can be used for all the body fluids including CSF and HPV DNA. This LBC(liquid based cytology) kit can be used to make smears Easy. Our liquid based cytology kits are applicable for GYNAE, NON GYNAE which includes all the Body fluids, HPV DNA and for FNAC’s as well.

How do you perform a cytology test?

A urine cytology test requires a urine sample, which you provide by urinating into a sterile container. In some cases, a urine sample is collected using a thin, hollow tube (catheter) that’s inserted into your urethra and moved up to your bladder.

Why is LBC better than Pap smear?

Its sensitivity, specificity as well as accuracy were much higher than the conventional method. LBC can be better method of cytological follow up of post-treated patients of cancer cervix apart from a reduction in adequate smears.
