The Liquid-based Cytology Brush, manufactured by the specialized medical product company LucentMed, features a curved brush head and a three-dimensional structure with multiple rows of bristles; this design enables the collection of an ample cellular sample, thereby enhancing the sensitivity and negative predictive value for the detection of early-stage lesions.
The liquid-based cytology brush is a disposable medical device designed to collect cell samples from the cervix and endocervical canal, primarily for use with liquid-based cytology testing.
Featuring soft, flexible bristles, the brush enables the uniform collection of exfoliated cells from both the cervical surface and the endocervical canal. The brush head is subsequently placed into a preservation solution for processing, ensuring high-quality samples for downstream cytological analysis.
Compared to traditional smear sampling methods, this specialized brush enhances the integrity of cell collection and the quality of sample preservation, making it suitable for applications such as gynecological check-ups, cervical cancer screening, the diagnosis of gynecological conditions, and clinical laboratory testing.
The brush head features soft, flexible nylon bristles that ensure thorough contact with the external cervical os and the endocervical canal. This design facilitates the collection of a higher yield of viable cells while minimizing tissue irritation and enhancing patient comfort.
The handle is constructed from medical-grade plastic, offering excellent strength and a secure grip, allowing healthcare professionals to precisely control the sampling process.
The brush supports a customizable snap-off design; upon completion of sampling, the brush head can be placed directly into the preservation solution. This minimizes cell loss during sample transfer and improves testing efficiency.

LucentMed offers a range of standard packaging options as well as OEM/ODM custom packaging solutions tailored to clients' sales channels, brand positioning, and shipping requirements.
Our standard packaging method features each Liquid-based Cytology Brush in individual sterile packaging (EO sterilized). This meets the procurement needs of medical institutions, minimizes the risk of cross-contamination, and allows healthcare professionals to use the product immediately.
We use high-strength, export-grade corrugated cardboard cartons that are moisture- and crush-resistant. We support specific packing quantities and offer customization for shipping marks and carton labeling.
In addition to standard options, LucentMed provides one-stop custom packaging services based on client needs, including:
Packaging formats: Individual packaging, combination packs, kit packaging, etc.
Branding: Logo printing, private labeling, and custom brand packaging.
Packaging design: Color boxes, instruction manuals, hang tags, and label design.
Multilingual support: Packaging available in English or multiple languages to suit target markets.
Export packaging optimization: Designed to meet the requirements of sea, air, and cross-border logistics.
A: The Liquid-based Cytology Brush is specifically designed to collect exfoliated cervical cells and is suitable for early cervical cancer screening.
A: Cervical precancerous lesions commonly occur in the squamocolumnar junction—an irregularly shaped area situated between the external cervical os and the endocervical canal.
The broom-like brush head design allows it to conform to both the external cervical os and the inner wall of the endocervical canal with a single rotation.
A: A single rotation of the LucentMed disposable sterile cervical brush collects over 1.4 million exfoliated cervical cells, far exceeding the minimum cell count required for liquid-based cytology testing (typically 50,000–100,000).
