FNAC tests are performed by healthcare professionals, such as radiologists, pathologists, or interventional specialists. To have an FNAC test, you need to schedule an appointment with a healthcare provider who performs the procedure. During the appointment, the healthcare provider will explain the procedure, obtain your consent, and perform the FNAC. It is important to follow any specific instructions provided by the healthcare provider regarding fasting (if required), medications, or any other preparations. After the procedure, the collected samples are sent to a laboratory for analysis. The FNAC test is conducted by medical professionals, and you do not need to collect the samples yourself.
