    For Labs

    In processing, the samples are concentrated, preserving the cells and removing many of the contaminants, such as mucus and inflammation. Then the concentrated cells are removed and preserved, requiring a small amount of the collected cells for initial testing. This allows for multiple tests to be run of a single collection sample.

    CUBLIQ (Liquid cover glass)


    • An optional component in the Citofem System is CUBLIQ™ which is a proprietary resin that hardens in 15 minutes and does not require mounting medial. CUBLIQ™ may be used with any cytological or histological specimen (except wet mounts)."
    • The display of the processed sample at the microscope is high quality as there tends to be no bubbles.
    • When the slides are not used (3 to 5 years later), the material encapsulated by CUBLIQ™ can be removed (such as removing an adhesive). The slide may then be recycled.
    • In the staining battery, it is not necessary to use Xylene. This implies that after passing through the EA50 stain and alcohol, the slides are dried and then coated with CUBLIQ™ This prevents chronic toxicity inhalation from organic solvents.
    • The price of CUBLIQ™ liquid glass cover glass is lower than the traditional cover slip making it much more economical.

    Citofem – the product

    " World Health Organization data shows that a woman dies somewhere in the world every two minutes as a result of cervical cancer. Medical professionals worldwide recommend periodic testing for all women, beginning shortly after their first sexual activity. For more than 50 years the only option for detecting cervical cancer has been the traditional test known as the "Papanicolaou test" or "smear", commonly referred to as the "Pap

    While the Pap has led to widespread screening in many parts of the world, cervical cancer screening had not experienced any technological advances until the recent introduction of "liquid cytology" technology. Liquid cytology procedures for cervical cancer screening far surpass the Pap in the quality of their results -- in accuracy, in precision, and in depth of analysis. These results have been scientifically validated and liquid cytology procedures are now available worldwide for cervical cancer screening.

    Citofem is different. It achieves the same superior results of all liquid cytology products. But, Citofem's approach includes a very simple manual procedure for sample preparation that eliminates the need to purchase costly equipment. Analysis requires no specialized training, and requires no additional purchases of related laboratory equipment or supplies. All that is needed to carry out the tests is found in the kit provided by Citofem at a price comparable to the traditional Pap.

    Advantages

    Better test results [compared with the traditional Pap test]

    • Liquid cytology results in a significant reduction in false negatives, resulting in an increase in the diagnosis of the disease in it’s early stages.
    • Liquid cytology is also responsible for a reduction in inconclusive results arising from atypical squamous cells (ASC) or inflammatory material.
    • Liquid Cytology results in an increased level of detection of low grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL).
    • Citofem is a complete liquid cytology system for the early detection of cervical cancer.

    Technological Advantages

    • Cervical cells are taken with the Rovers® Cervex-Brush® Combi, the world’s most technologically advanced brush for cervical sampling, extracting a large number of cells for the earlier detection of cancer.
    • Cells to be analyzed are optimally preserved morphologically for a more accurate analysis.
    • One hundred percent of the patient's sample is sent to the lab for processing, enabling the preparation of multiple slides; providing an excellent opportunity to carry out further tests. This feature dramatically reduces the backlog in any laboratory and also eliminates the usual 6-month waiting period for retests. It will allow for HPV and histo-chemical immunology tests utilizing any FDA approved molecular test.
    • Citofem is processed without using xylene in the staining phase, ensuring a safer process and improved working environment.
    • Cells to be analyzed are deposited next to each other in the form of a mosaic in monolayers, concentrated over a small area, but sufficient for a diagnosis. This dramatically allows cytology technicians to analyze more slides per hour, reducing laboratory backlogs.
    • The majority of mucus, blood, inflammation, etc. is removed from the sample.
    • Cells are fixed on the slide with a resin (Cubliq®) that ensures high optical quality, reduces breakage, and eliminates the use of mounting media and slide covers. This enables a more cost-effective study.
    • Citofem is formulated to provide all the advantages of the latest liquid-based cytology technology, without the need to use expensive high-cost equipment or to invest in special training

    For Patients

    In the fight against cervical cancer, there are many clear advantages to using Liquid Based Cytology (LBC) as the primary screening tool. LBC is quality and affordable product which is easy to use for for patients, medical professionals and laboratory workers. The testing materials, combined with no ancillary fees in terms of additional equipment requirements, make Citofem an affordable choice.

    The pap smear:

    was useful as it was the test that brought out women in high numbers to the lab. The benefit of a greater amount of women being tested saved lives. Today, however, liquid cytology and especially Citofem provide women a much greater level of protection

    Finally you have Citofem, a test method at a low cost but with technical advantages that translate directly into greater security to its patients. We feel that Citofem is the logical substitute of the pap smear the second most used medical diagnostic test worldwide.

    Why should we switch to Citofem worldwide right now?

    • 100% sample preservation (no other system has this)
    • 3x more endocervical cells (earlier stages of can be detected)
    • 10x faster in sample processing and in sample analysis than pap
    • 70% plus removal of interfering substances in the sample
    • multiple slides per patient (an option only with this system)
    • and it is cost equivalent to the traditional pap smear

    Scientific Discussion of Citofem

    In 2000 Payne and Chilcott (Sheffield, UK) completed a study validating the advantages of liquid cytology over the pap smear tests. They found that screening for cervical cancer using liquid cytology decreased the incidences of false negatives by 11% and increased the detection (positive diagnoses) by 9% over the pap test.

    Sometimes also known as monolayer cytology, liquid cytology has demonstrated in other studies to be significantly superior to the pap smear in sensitivity (gains of 9% found by Coste, J in 2003. BMJ) and in specificity (gains of 10% in specificity was reported by Kulasingam, SL in 2004.JAMA).However a study by Willis, BH in 2005 found no additional gains when liquid cytology was automated (Health Technol).

    That is why we believe Citofem garners all the benefits of liquid cytology (even exceeds them) and does not burden the test system with automation that adds expense without adding technical advantage.

    Right now Citofem is the test system of choice for the detection of cervical cancer worldwide. And let's not forget Citofem's very high retrieval of endocervical cells that opens the window to the diagnosis of those earlier stages of cervical cancer
