How HALO Works
The HALO Breast PapTest is the only fully automated, noninvasive NAF collection system designed for use in the primary care office. Its three main components include:
- HALO Console
- Patient Interface Cassette with fluid reservoir and adjustable breast cups
- Disposable Sample Collection Cups

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: Lack of NAF indicates that relative risk for breast cancer is unchanged. The presence of atypical cells increases the relative risk by a factor of 2.0 to 4.9. (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.
