Cyst fluid cytology

This test uses a microscope to evaluate the cells of a fluid sample collected from a cyst. It is used to help diagnose lumps or masses as cancerous or non-cancerous. This test is used in cyst of the ovary, neck mass, or cyst of the thyroid gland.

Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:

• Cyst of central nervous system
• Cyst of ovary
• Cyst of thyroid
• Lump on neck

Written consent may be required for a fine needle aspiration biopsy. Review the consent form with the healthcare worker and ask any questions you have before signing the form. Tell the healthcare worker if you have a medical condition or are using a medication or supplement that causes excessive bleeding. You should also report if you have a history of allergic or other reactions to local anesthetics.

A fine needle aspiration biopsy is used to collect fluid, or take small tissue samples from a cyst, lump or mass. First, the area over the biopsy site will be cleaned. A local anesthetic may be used to numb the area where the needle will be inserted.

A very tiny needle will be inserted into the area selected for testing. If fluid is present, it will be withdrawn from the area using a syringe. If a tissue sample is required for testing, the needle may be moved back and forth to get enough tissue. When sample collection is complete, the needle will be removed.

The healthcare worker may use an ultrasound machine during this test.

The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the procedure. Inform the person doing the procedure if you feel that you cannot continue with the procedure.

A local anesthetic is used to minimize pain during a fine needle aspiration biopsy. Even when local anesthetic is used, you may feel discomfort or pressure as the needle is inserted and moved during the procedure. After the biopsy, the procedure site may be sore for several days.

After a fine needle biopsy, pressure may be held to the site briefly and a small bandage will be placed over the biopsy site. Ask for instructions for when to remove the dressing and how to monitor for signs and symptoms of infection. Contact your healthcare worker if you have a fever or increased pain, and if you see increasing redness, swelling, or pus at the procedure site.

You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
