FNAC: During fine needle aspiration cytology (FNAC), a long thin needle is inserted into the suspicious area. A syringe is used to draw out fluid and cells for analysis to check the nature of cells like cancer or non cancerous cells.  FNAC test are done for most organs in the body like liver FNAC, renal or kidney FNAC, lymph node FNAC, lung FNAC, breast FNAC, thyroid FNAC, etc

Biopsy: A Biopsy Test is a sample of tissue taken from the body in order to examine it more closely. A doctor will recommend a biopsy when an initial test suggests an area of tissue in the body isn’t normal. Doctors may call an area of abnormal tissue a lesion, a tumor, or a mass. Biopsy test is usually done to check the nature of cells like cancer or non cancer, infection or inflammation. Biopsy test are done for most organs in the body like liver biopsy, renal or kidney biopsy, lymph node biopsy, bone biopsy, lung biopsy, breast biopsy, skin biopsy, thyroid biopsy, etc

Aspiration: The act of removing a fluid, as pus or serum, from a cavity of the body, by a hollow needle or trocar connected with a suction syringe. Aspiration test done for abscess, collection or fluid in most parts of body like liver abscess aspiration, ascitic fluid aspiration, pleural fluid aspiration, cyst aspiration, abscess aspiration, etc

Catheter Drainage: Image-guided percutaneous drainage involves using a catheter (a thin tube) to drain an abscess or a collection of fluid or air under image guidance. Catheter Drainage procedure done for abscess, collection or fluid in most parts of body when aspiration is not helpful like liver abscess catheter drainage, ascitic fluid catheter drainage, pleural fluid catheter drainage, abscess collection catheter drainage, etc
