Cytology - Fluid/Lavage, Cell Block Test

Cytology is the study of cells, and cytological analysis is a diagnostic method used to examine cells from various body fluids or surfaces. The Cytology - Fluid/Lavage, Cell Block Test involves analyzing cells obtained from body fluids or through lavage (washing) of certain body cavities. This test is particularly useful in diagnosing infections, inflammations, and cancers. Cell block technique is used to process the fluid sample in a manner that allows thin sections to be cut for microscopic examination, similar to how tissue biopsy samples are prepared.


A sample of fluid (such as pleural, peritoneal, or bronchial fluid) or washings from a body cavity is collected by a healthcare provider. The sample is then processed and examined under a microscope to evaluate the cells' characteristics.

  • Profile Name: Cytology - Fluid/Lavage, Cell Block Test
  • Sample Type: Fluid/Lavage
  • Preparations Required: No special preparation is required for this test.
  • Report Time: 2 days

What is the purpose of the Cytology - Fluid/Lavage, Cell Block Test?

This test is used to analyze cells in body fluids or washings from body cavities to detect abnormalities, infections, inflammations, or cancers.

How is the sample collected?

The sample is collected by aspirating fluid from body cavities such as the pleura or peritoneum, or by washing (lavage) a body cavity and collecting the fluid. The method of collection depends on the clinical question and the body site involved.

Frequently Asked Questions

A cell block is a technique where the cells from a fluid sample are processed into a solid form, allowing thin sections to be cut and stained for microscopic examination, similar to tissue biopsies.

The discomfort experienced during sample collection varies depending on the site from which the sample is obtained. For example, a bronchoalveolar lavage may cause mild discomfort, while obtaining fluid from the pleural cavity may cause moderate discomfort.

This test can detect infections, inflammations, and malignant cells indicative of cancer. It can also identify other cellular changes that may indicate specific non-cancerous conditions.

While both tests are used to analyze cells under a microscope, cytology examines cells that are shed into body fluids or obtained through lavage, whereas a biopsy involves removing a small piece of tissue for examination.

Yes, this test can be used to diagnose lung cancer, especially when analyzing cells obtained through bronchoalveolar lavage or pleural fluid.

Staining is essential in cytology as it enhances the contrast of the cells and allows for the identification of specific cell structures and abnormalities under a microscope.

The risks are generally low but depend on the site of fluid collection. For example, collecting pleural fluid might carry risks such as infection or pneumothorax (collapsed lung), though these are relatively rare.

Generally, no special preparation is needed. However, it's essential to follow any instructions given by your healthcare provider, as some procedures for collecting samples may require specific preparations.

It typically takes between 3-5 days to receive the results, but this can vary depending on the laboratory.

If the results show abnormal cells, it is important to follow up with your healthcare provider to discuss the findings and determine the next steps for further evaluation or treatment.

To some extent, yes. The appearance of malignant cells under the microscope can sometimes indicate the type of cancer, but additional tests may be needed for a definitive diagnosis.

In case of abnormal results, you should consult the doctor who ordered the test. Depending on the findings, you may be referred to a specialist such as an oncologist, pulmonologist, or infectious disease specialist.

Yes, in some cases, repeated cytological analysis of body fluids can be used to monitor how well a cancer patient is responding to treatment.

Understanding the cells' characteristics through the Cytology - Fluid/Lavage, Cell Block Test is vital in diagnosing and managing various conditions, including cancer. This test, although simple, can provide critical information to healthcare providers. If you are advised to undergo this test, it is essential to follow your healthcare provider's instructions and openly discuss any concerns you may have.
