The FirstCyte® Breast Test
The FirstCyte Breast Test involves gently rinsing the inside of your patient's
milk ducts to collect cells. The sample is then sent to a lab for cytological
analysis to determine whether the cells are normal, atypical or malignant.
The FirstCyte Breast Test is an office-based or outpatient procedure that is
comfortable for most patients.
- To help ensure procedure comfort, a small amount of anesthetic is applied topically and intraductally. On average, study subjects surveyed during the procedure did not find it painful (a median response of 24 on a 100-point pain scale).1
The FirstCyte Breast Test involves three steps:
Step 1: Aspiration with the FirstCyte Aspirator
|
The aspirator is used to elicit a small amount of nipple aspirate fluid (NAF). NAF determined which (if any) ducts to lavage, and helps locate the natural openings of fluid-yielding ducts.
- A gentle suction is applied with the aspirator to draw fluid to the surface of the nipple.
- In a multi-center clinical trial, 84% of subjects yielded NAF upon nipple aspiration. 1
- Among NAF-yielding subjects, 96% yielded fluid from 1 to 3 ducts.1

Step 2: Using the FirstCyte E•Z® MicroCatheter
 |
- A flexible microcatheter is inserted about 1 cm into the milk duct through the duct's natural opening on the nipple surface.
- A small amount of lidocaine is infused through the catheter to anesthetize the duct.
- Fluid is then slowly introduced into the milk duct to rinse the duct and collect epithelial cells.
|
Step 3: Sample preparation and analysis
 |
- The fluid is deposited into a vial of CytoLyt® solution, a cell preservative, and is sent to a cytology lab for analysis.
- The fluid is then analyzed cytologically to determine the presence of normal, atypical, or malignant cells.
