The HALO Breast Pap Test - a simple 5-step cycle

The HALO Breast Pap Test allows a physician's office staff to perform noninvasive NAF collection in about five minutes. The system incorporates heat, suction and massage in a single, fully automated cycle.

Step 1: Insert Disposable Sample Collection Cups

New Disposable Sample Collection Cups are inserted into Adjustable Breast Cups for each patient.

Step 2: Preparing the Breasts

The nipples are cleansed with the alcohol swab provided.  Adjustable Breast Cups are placed on the patient’s breasts adjusted to fit.

Step 3: Suction and Heating and Compression Cycles

The HALO console initiates gentle suction (similar to that of a breast pump) on both breasts. Simultaneously with suction, warmth is applied and then a massage is initiated.

Step 4: Fluid Samples Obtained

Once the cycle is complete, Breast Cups are removed from the patient and any NAF sample is collected with a swab (included), placed into a liquid cytology vial, and sent to a cytology lab for examination.

*NOTE: Not all women will produce a NAF sample. Lack of NAF in the ducts has clinical significance, as absence of fluid production indicates reduced relative risk for breast disease. (Wrensch et al, JNCI, 2001)

Step 5: Removal and Disposal of Disposable Sample Collection Cups

Disposable Sample Collection Cups are removed and disposed of at the end of each HALO Breast Pap Test.
