Cytology, Fine Needle Aspirate
Also known as: FA REQUEST
Use
The fine needle aspirate test is used to establish a diagnosis for mass lesions that are accessible by cytology sampling. This may include lesions in organs such as the thyroid, breast, kidney, liver, lymph nodes, and salivary glands. The test is typically performed to determine the nature of the mass, whether benign or malignant, and to assess any specific pathological characteristics.
