Oral Fluid Collection Media

Filtrona Fibertec® Trasorb® SCM (Saliva Collection Media) is ideal for obtaining oral fluid diagnostic samples.  Drawing on a broad range of fiber types, Filtrona Fibertec customizes Transorb SCM for optimum saliva absorption and recovery of targeted analytes. Media components are self contained and structurally sound, with no fraying or shedding. Filtrona Fibertec components can be made nonabrasive and of proper texture to ensure comfort and prevent the introduction of blood contaminants to the sample. Filtrona Fibertec Transorb SCM is especially well suited for drugs-of-abuse applications. Transorb SCM has been precisely engineered to maximize THC recovery, with independent data suggesting recovery rates over 98% at 5ng/mL concentrations.


Customized Rapid Diagnostics Media

Filtrona Fibertec® Transorb® Rapid Diagnostics Media is ideal for use as precise wicking materials, absorbent pads, and in some applications, conjugate pads, for lateral- flow assay applications. The media may be engineered to select capillarity and sample volumes and resistant to non-specific binding.  Its high tensile strength delivers optimum processing mechanics in roll stock form.  Filtrona Fibertec media will not crimp or tear as cellulose-based products.  In-house fiber processing and development enables lot-to-lot consistency and within-lot uniformity. Filtrona Fibertec manufactures bonded fiber components used to collect, wick, manipulate, control or filter diagnostic samples and other fluids on the microliter and milliliter scale.


2nd Generation Direct Hemoglobin A1c Reagent

This 2nd generation reagent for the determination of HbA1c on chemistry analyzers has improved stability of the sensitivity of the combined R2 reagents. As a result, in many settings, calibration stability and combined R2 reagent stability will be improved. The percentage of HbA1c is determined directly using on-board lyse applications on many chemistry systems. The method is based on competitive binding, latex-enhanced immunoturbidimetric analysis. The reagents are liquid stable and easily adapted to analyzers capable of handling two reagents. The four-level calibrator set is NGSP certified with values provided in percentage of HbA1c. A two-level control set is also available.

Urine Collection System

Introducing the Void Ease Bag for the collection of urine for urine tests. The bag makes urine collection easier, especially for women and children compared to the traditional cup, and the contents will not leak due to the patented, one-way valve. The urine sample can be extracted directly from the collection bag to the attached test tube for distribution to the testing laboratory. In addition, the specimen tube can be refrigerated to avoid corrupting the urine sample. With its sealed design of collection, extraction, and containment system, the Void Ease Bag also prevents contamination of lab professionals. In addition, urine spills are avoided because transferring the urine to a test tube is avoided.

Jaguar Analyzer

The Jaguar analyzer will automatically perform all aspects of nucleic acid testing, including sample preparation, amplification, and detection for up to 48 samples per hour with the first 24 results available in less than an hour. The Jaguar system will enable customers to overcome the three main disadvantages of NAT: time, complexity and cost. Contamination and carryover risks, which are high in current NAT environments that are dependent upon manual sample preparation and processing steps or “open tube” PCR, drop to nearly zero. Training requirements are expected to change from long and complicated to brief and simple, plus the Jaguar instrument's performance is expected to meet or exceed current NAT systems and culture. Jaguar offers a radical, yet logical and straightforward, advancement in nucleic acid testing.

Hemosure® One-Step Immunological FOBT

The one-step, easy to use Hemosure immunological FOBT is the latest technological breakthrough in immunological fecal occult blood testing (IFOBT). FDA approved and CLIA waived, the Hemosure immunoassay employs a unique combination of monoclonal and polyclonal antibodies to detect only human blood in stool. As a result, abstinence of food and drugs before taking the test is no longer necessary, advantages that can significantly enhance patient compliances.

QUANTA Lite™ CCP3.1 Assay

The QUANTA Lite CCP3.1 IgG/IgA (cyclic citrullinated peptide) ELISA is an improved version of CCP3, the third-generation assay, featuring a blended, dual-specificity IgG/IgA conjugate. The exact sequence of CCP3.1 is proprietary and patent pending. Antibodies from patients with rheumatoid arthritis (RA) react very specifically with CCP on the solid phase. The use of a blended anti-IgG and IgA affinity-purified conjugate allows the detection of antibodies in a small but significant cohort of RA patients that do not react with IgG alone. The QUANTA Lite CCP3.1 ELISA offers up to a 9% increase in sensitivity for the detection of early RA patients over that seen with CCP2. In addition, the specificity of CCP3.1 is increased over that observed in earlier CCP2 assays.

QUANTA Lite™ Celiac DGP Kits

The QUANTA Lite Celiac DGP (deamidated gliadin peptide) IgG, IgA, and screening kits feature a novel, entirely synthetic peptide. While the exact sequence is proprietary and patent pending, the molecule contains fewer than 35 amino acids. This peptide is derived from whole molecule gliadin and has been selectively deamidated, causing glutamine to convert to glutamic acid, thus mimicking the action of tissue transglutaminase (tTG). The peptide incorporates the major B cell epitopes in a conformationally intact manner. These kits offer greater than 97% agreement with tTG and endomysial results, vastly enhanced specificity with a less than 1% false-positive rate, and increased sensitivity for the detection of celiac disease.
