COVID-19 Antibody Testing - DiaSys SARS-CoV-2 UTAB FS - coming soon

In response to COVID-19, DiaSys currently develops a serological assay to detect SARS-CoV-2 total antibodies. This test allows identification of individuals who have developed an immune response against the virus, even if they were asymptomatic or never have been diagnosed with the disease.

The SARS-CoV-2 UTAB FS assay is a particle enhanced immunoturbidimetric assays (PETIA) which enable a qualitative resp. semi-quantitative detection of total antibodies to SARS-CoV-2 in human serum and plasma. Since neutralizing antibodies directed against the spike protein can induce protective immunity against viral infection, the new DiaSys assay SARS-CoV-2 UTAB FS targets antibodies directed against the receptor binding domain (RBD) of the viral spike protein. This region is responsible for binding to the host cell receptor, allowing the virus to enter the host cell. The serological test offers high specificity and sensitivity and shows no cross-reactivity to the four human coronaviruses, which share partial sequence homology with SARS-CoV-2. Therefore, it reduces the risk of false positives due to the detection of similar antibodies that may be present. The innovative DiaSys reagent and the dedicated calibrators and controls will be available as liquid-stable products. The suffix UTAB - Universal Total Antibody - in the product name refers to the fact that this test can be applied on almost all clinical chemistry analyzers.

COVID-19 Antigen Rapid Test - immediately available

DiaSys is pleased to provide a rapid test for qualitative detection of specific antigens in COVID-19. The gold nanoparticle-based immunochromatographic test, SGTi-flex COVID-19 Ag, enables a qualitative determination from nasopharyngeal swab. It offers high sensitivity and specificity, and shows no cross-reactivity by other viruses or pathogens. The test delivers results within only 20 - 30 minutes. It does not require any additional materials or device, thereby, increasing the testing capacity, especially in countries that do not have extensive laboratory facilities for molecular testing (polymerase chain reaction or PCR).

COVID-19 IgM/IgG Antibody Rapid Test - immediately available

With immediate effect, DiaSys offers a rapid test for the detection of IgM and IgG antibodies in COVID-19. The gold nanoparticle-based immunochromatographic test SGTi-flex COVID-19 IgM/IgG allows qualitative determination in whole blood (finger prick blood), serum und plasma. It exhibits high specificity and sensitivity, shows no cross-reactivity by other viruses or pathogens and delivers reliable results within 10 to 15 minutes. The new product will positively contribute to pandemic management because this test is fast, reduces workload on centralized testing laboratories and is the test of choice in resource-limited countries.

DiaSys Parameters in COVID-19 Monitoring

Laboratory medicine plays an important role in early detection, diagnosis and treatment of COVID-19. The IFCC has published an information guide on biochemical monitoring of COVID-19 patients. DiaSys offers a variety of reagents for parameters that are recommended for monitoring of the disease. For more information on DiaSys parameters in COVID-19 monitoring, please visit the attached pdfs where you can find summaries for each parameter.

Procalcitonin FS

Serum procalcitonin (PCT) levels are a sensitive marker for severe and systemic bacterial infections. PCT is primarily produced in thyroid C cells as a precursor of calcitonin but expressed in nearly all tissues by stimulation of interleukins and bacterial endotoxins. In healthy individuals, PCT concentrations are usually below 0.05 ng/mL, and a significant increase of PCT up to a thousand-fold appears within a few hours in patients with severe and systemic bacterial infections.

DiaSys Procalcitonin FS is a fluid-stable, particle enhanced immunoturbidimetric assay with outstanding onboard and calibration stability, providing a convenient workflow on clinical chemistry analyzers. Determinations of PCT in serum and plasma within the measuring range from 0.2 ng/mL to 50 ng/mL can be performed with high precision at clinical cut-off levels for sepsis. The performance is complemented by high tolerance to endogenous interferents and various therapeutics used in sepsis management. Procalcitonin FS shows a good correlation to established methods. Results from ring trials and a publication demonstrate the strengths of the assay.

Water Purification Systems by DiaSys

The accuracy and reliability of measurement results depend to a large extent on the quality of the process water used.

The DiaSys water purification systems O classic, O mini and O maxi work with coordinated cleaning steps to produce purest water of highest quality. The systems are designed to work perfectly with our analyzers. They produce from 15 L/h up to 55 L/h and have a water buffer tank from 9 L up to 75 L capacity. With these water treatment systems and together with our reagents and analytical instruments, DiaSys offers the complete package for reliable results.

In addition, the respons®920 and respons®940 analyzers offer the option of using an autofilling system to avoid the inconvenience of filling the deionized water tank. The autofilling system is installed directly in the deionized water tank and connected to the water purification system, eliminating the time needed to refill the water tank and eliminating the risk of the analyzer stopping due to lack of water. This makes your laboratory work even more efficient.

DiaSys – Choosing Quality. Also for laboratory water!

Total bile acids 21 FS

Increased serum bile acid levels are associated with several diseases such as acute and chronic hepatitis, intrahepatic cholestasis of pregnancy, liver sclerosis, cirrhosis, and cancer. Commercially available assays show limitations regarding the detection of clinically relevant primary and secondary bile acids. DiaSys introduces a liquid-stable, ready-to-use reagent with excellent recovery of diagnostically relevant bile acids (target deviation ≤ 7%). DiaSys Total bile acids 21 FS has a wide measuring range, good precision and long onboard and calibration stability. DiaSys provides a dedicated calibrator for optimum performance and multi-parameter controls for a convenient workflow.

β-Hydroxybutyrate 21 FS

Diabetic ketoacidosis is an acute, life-threatening complication which should be detected and treated immediately. Urine test strips that are commonly used for detection of ketoacidosis, are associated with several limitations. Since β-hydroxybutyrate levels increase more rapidly than levels of acetoacetate and acetone, serum/plasma β-hydroxybutyrate determination is a superior biomarker for ketoacidosis and recommended by the American Diabetes Association. Benefits are a minimized risk for false negative results, earlier identification and treatment through quantitative results and measurements that are less susceptible to drug interference.

With β-Hydroxybutyrate 21 FS, DiaSys offers a liquid-stable, ready-to-use reagent applicable to common clinical chemistry analyzers. The assay is suitable for serum and plasma samples, has a wide measuring range, excellent precision and superior calibration and onboard stability of up to 12 weeks. The test includes the DiaSys Lipid Clearing System, assuring correct results unaffected by lipid interference.
