From the Guidelines
A non-gynecological cytology test is a diagnostic procedure that examines cells from non-reproductive organs or tissues to detect abnormal cell growth, cancer, or other conditions.
Examples of Non-Gynecological Cytology Tests
- Thoracentesis: a procedure that involves collecting a sample of pleural fluid to diagnose lung cancer, as recommended by the American College of Chest Physicians evidence-based clinical practice guidelines 1
- Sputum cytology: to diagnose lung cancer
- Fine-needle aspiration cytology: to evaluate thyroid nodules
- Urine cytology: to detect bladder cancer These tests typically involve collecting a sample of cells from the affected area using a brush, needle, or other instrument, which is then examined under a microscope to identify any abnormal cell morphology.
Key Considerations
- The diagnostic yield of non-gynecological cytology tests depends on various factors, including sample preparation, the experience of the cytologist, and the type of tumor 1
- Ultrasound guidance can improve the accuracy and safety of these tests, particularly in the case of thoracentesis, by reducing the incidence of iatrogenic pneumothorax 1
From the Research
Definition of Non-Gynecological Cytology Test
A non-gynecological cytology test refers to the examination of cells from non-gynecological sites, such as the lung, thyroid, breast, lymph nodes, and other organs, to aid in the diagnosis of various diseases, including cancer [ 2, 3,4,5,6 ].
Types of Non-Gynecological Cytology Tests
Some common types of non-gynecological cytology tests include:
- Fine needle aspiration (FNA) cytology [ 2, 4,5,6 ]
- Liquid-based cytology (LBC) [ 2, 5,6 ]
- Conventional smears 5, 6
Characteristics of Non-Gynecological Cytology Tests
Non-gynecological cytology tests have several characteristics, including:
- Examination of cells from non-gynecological sites [ 2, 3,4,5,6 ]
- Use of various techniques, such as LBC and conventional smears 5, 6
- Importance of cellular morphology and architecture in diagnosis 4, 5, 6
Applications of Non-Gynecological Cytology Tests
Non-gynecological cytology tests have various applications, including:
