Understanding the FNAC test results
At the laboratory, a pathologist observes the collected tissue, cell, or fluid under a microscope. The fine needle aspiration cytology test accurately diagnoses the exact location of tumors or lesions.
It also detects the extent of the abnormalities and the disorder that is the underlying cause of the symptoms. The course of treatment is decided by your doctor based on the results of the FNAC test. There is a risk of the test generating a false negative result.
When should it be repeated?
In case your doctor suspects a false negative result, he/she may advise you to do a repeat fine-needle aspiration cytology test.
If there is a recurrence of a tumor, cyst, or growth that needs to be studied, your doctor may advise you to repeat the test as appropriate. A repeat test will also be done if you are under treatment and the condition reappears.
Procedure for the FNAC Test
A narrow-gauge needle, which is attached to a syringe, is inserted into the organ which is to be biopsied. The purpose of this process is to remove a small part of the lesion in the organ as a sample.
The medical expert performing the biopsy test sucks cells, tissues, or fluid from the relevant organ and collects it in the syringe that is attached to the needle. This sample is sent to a laboratory for microscopic evaluation.
The pain of this minimally invasive aspiration cytology test varies between patients. Some patients may experience mild pain and/or inflammation at the surgical site after a few days of the biopsy test. Your doctor may advise a pain reliever like paracetamol to soothe the discomfort and heal the wound. Follow the doctor’s advice.
