ohutneulanäytteen

Ohutneulanäyte, known in English as fine-needle aspiration (FNA), is a diagnostic procedure used to obtain cells from a suspicious lump or area of the body. A very thin needle, typically 25-gauge or smaller, is inserted into the lesion, and a small amount of fluid or cells is withdrawn. This sample is then sent to a laboratory for microscopic examination by a pathologist.

The procedure is generally quick and well-tolerated, often performed in an outpatient setting. It can be used to evaluate masses in various locations, including the thyroid, lymph nodes, breasts, and salivary glands. FNA is particularly useful for differentiating between benign and malignant conditions. The results can guide further treatment decisions, such as whether surgery is necessary or if other diagnostic tests are required.

While generally safe, potential complications of ohutneulanäyte are minimal and may include minor bleeding, bruising, or infection at the needle insertion site. In some cases, the sample obtained may not be sufficient for diagnosis, requiring the procedure to be repeated. The interpretation of the results depends on the expertise of the pathologist and the quality of the collected sample. Ohutneulanäyte is a valuable tool in medical diagnostics, offering a minimally invasive way to gather crucial cellular information.
