Using four different detection technologies, the CS-5100 delivers great quality analyses. With clotting, chromogenic, immunoturbimetric and platelet aggregation assays it delivers accuracy and precision for all parameters. Clotting method The CS-5100 uses the Optical Detection Method to detect the change in turbidity of the sample-reaction mixture during the coagulation process. This is reflected in the change in scattered light intensity when fibrinogen is converted into a fibrin mesh. Light strikes the reaction mixture, after the scattered light intensity is received by a photodiode. This converts the light intensity into electrical signals and is used to find the coagulation time. This method is used to measure prothrombin time, APTT, fibrinogen, factors and many other clotting tests. Chromogenic method Light with a wavelength of 405 nm passes through the sample and reagent mixture and reaches a photodiode, where the transmitted light is converted into electrical signals. The change in the intensity of this transmitted light is used to determine the change in absorbance. This measurement is used for chromogenic assays like Antithrombin and Protein C where a chromogenic substrate in presence of an activator causes the reagent mixture to change colour. Immunoassay and platelet aggregation method The sample-reagent mixture contains artificial particles that can aggregate when there is an antigen-antibody reaction or particles that have a natural capability to aggregate like platelets. The mixture is exposed to light of a high wavelength, and the change in light absorbance caused by the formation of aggregates is detected as the change in transmitted light. This is used for D-dimer assays and platelet aggregation assays (Von Willebrand activity, ADP, Collagen, Arachidonic Acid, Epinephrine).

Pre-analytical issues can account for as much as 70% of a clinical laboratory’s errors. Multi-wavelength scanning and sample liquid-sensing technologies detect unsuitable specimens. A pre-analytical sample integrity check tests for interfering substances in the sample – haemolysis, icterus, lipaemia – at three wavelengths: 405 nm, 575 nm and 660 nm.

A primary tube sample volume check provides assistance by identifying potential inaccuracies caused by improper sample collection, which can result in an incorrect ratio of anticoagulant to patient plasma.

Under specific conditions, the CS-5100 will automatically use the optimal wavelengths to ensure result accuracy in the presence of hemolysis, icterus or lipemia. This minimises the need for retesting and helps you deliver the highest quality results on your first test run.

Using a multi-wave detection system, the CS-5100 can simultaneously measure multiple parameters using four different measurement methods: coagulation, chromogenic, immunoassay and aggregation. The system’s photo-optical clot detection means you have several advantages compared to mechanical detection.

• You can measure light transmittance over the entire course of clot formation, not just the end.
• You can identify atypical reaction patterns easily and so determine the correct coagulation reaction result for your patients with unusual in vitro clot reactions such as sepsis and DIC.
• The clotting reactions display the complete clot signature, not just a single data point, so that you get far more detailed test information and therefore better clinical utility.

Used on a single platform, the broad range of assays allows high test throughput – up to 400 samples per hour.

In the CS-5100, we have critically addressed the usability of our coagulation analysers – based on extensive input from users and our own knowhow. One of the results is our new, cooled reagent system with secure, in-situ barcode reading.

Reagent racks are now placed in a double-ring reagent table capable of handling a total of 40 reagent bottles maintained at 10°C. The bottles are slightly tilted to reduce dead volume and reagent waste and maximize the number of tests per vial.

One position on each reagent rack can stir reagents so that you can use reagents that require continuous mixing.

A separate reagent rack system lets you group reagents for each rack and for high sample loads - up to three vials of the same reagent. With a onboard capacity of 1000 cuvettes this delivers a long walk-away time . To reduce the risk of errors, there is an optional automatic quality control when vials are changed.

• Convenient batch change with maximum security
• Accessibility for all users with standardized decision-making
• Excellent linearity negating multiple calibrations for different assay ranges
• Up to 12 dilution points for each calibration performed
• Up to 10 live calibration curves per assay
• Automatic recognition of the appropriate calibration curve.
