HemosIL Liquid Anti-Xa is a one stage chromogenic assay based on a synthetic chromogenic substrate and on Factor Xa inactivation. The assay provides quantitative results on 3.2% citrated human plasma for the following analytes based on the calibrators used: . When used with HemosIL Heparin Calibrators: Heparin levels in patient plasma are measured automatically on ACL TOP Family and ACL TOP Family 50 Series when this assay is calibrated with HemosIL Heparin Calibrators. Heparin is analyzed as a complex with antithrombin present in the sample. The concentration of this complex is dependent on the availability of the patient's endogenous antithrombin. When the heparinantithrombin complex is formed, two competing reactions take place. - 1. Factor Xa is neutralized by heparin-antithrombin complex. - 2. Residual Factor Xa is quantified with a synthetic chromogenic substrate. The paranitroaniline released is monitored kinetically at 405 nm and is inversely proportional to the heparin level in the sample. In order to reduce the influence from heparin antagonists, such as platelet factor 4 (PF4), dextran sulfate is included in the reaction mixture. When used with HemosIL Apixaban Calibrators: . Apixaban levels in patient plasma are measured automatically on ACL TOP Family and ACL TOP Family 50 Series when this assay is calibrated with HemosIL Apixaban Calibrators. Apixaban directly inhibits Factor Xa activity independent of the antithrombin present. The Factor Xa activity measured by the assay is exogenous. Factor Xa is neutralized directly by apixaban. Residual Factor Xa is quantified with a synthetic chromogenic substrate. The paranitroaniline released is monitored kinetically at 405 nm and is inversely proportional to the apixaban level in the sample. Measurement of apixaban concentration is recommended by the International Society of Thrombosis and Hemostasis Subcommittee on Control of Anticoagulation in certain clinical scenarios including bleeding episodes, perioperative management, and suspicion of overdose.

The INNOVANCE® Heparin assay is a one stage chromogenic assay. The reagent kit consists of two components. One component (INNOVANCE Heparin Reagent) contains Coagulation Factor Xa (Xa), the other (INNOVANCE Heparin Substrate) a chromogenic substrate specific for Xa. Upon mixing of INNOVANCE Heparin Reagent and INNOVANCE Heparin Substrate, Xa converts the chromogenic substrate into two products, one of them is paranitroaniline. The formation of paranitroaniline can be quantified by the coaqulation analyzer employing light absorption at a specific wavelength (405 nm). In the presence of a heparin containing sample the formation of paranitroaniline will be reduced in a time dependent manner. This is due to inhibition of Xa by the heparin/antithrombin (AT) complex. This complex is formed in the patient's plasma and competes with the substrate conversion by Xa. The concentration of the complex is not only dependent on the concentration of heparin but also on the availability of the patient's endogenous antithrombin. By comparison to a reference curve the heparin activity of the sample can be quantified. To reduce the influence from heparin antagonists, such as platelet factor 4 (PF4), dextran sulfate is included in the reaction mixture. The INNOVANCE® Heparin Calibrator consists of 5 calibrator levels. INNOVANCE® Heparin Calibrator 1 represents plasma containing no heparin. INNOVANCE® Heparin Calibrator 2, 3, 4 and 5 contain defined activities of LMWH and are calibrated against the World Health Orqanization (WHO) International Standards for UFH and LMWH. The calibrator levels are used to establish a reference curve (calibration curve) which then can be employed to quantify the heparin activity of UFH and LMWH containing plasmas. The INNOVANCE® Heparin Controls consist of plasmas containing defined activities of either UFH or LMWH. Recovery of these controls within their assigned ranges indicates proper functionality of the assay system.

The STA® - Liquid Anti-Xa is a chromogenic assay technique used for determination of the level of UFH and LMWH that have high affinity for antithrombin by measuring their anti-Xa activity. The method is a one-step reaction based on a similar principle: as soon as factor Xa is added to the plasma-substrate mixture, two reactions take place simultaneously, namely, hydrolysis of the substrate by factor Xa and inhibition of factor Xa by the heparin-antithrombin complex. After the necessary period of time for the competitive reaction to reach equilibrium, the quantity of paranitroaniline that is released is inversely proportional to the concentration of heparin present in the test medium. The STA® - Multi Hep Calibrator reagents are lyophilized human plasmas at five different heparin concentrations.

The Rapidpoint™Coag Enoxaparin Test card (ENOX) is a qualitative test intended for exclusive use with the Rapidpoint Coag analyzer to detect the anticoagulant effects, ≥ 1.0 IU/ml, of the low molecular weight heparin (LMWH), Lovenox®/Clexane® (enoxaparin sodium)¹, in arterial citrated whole blood from patients with unstable angina (UA)/non-ST segment elevation myocardial infarction (NSTEMI) who may transition to percutaneous intervention (PCI). The ENOX test is intended for use at either the point of care or in the central laboratory. The device does not discriminate between values of enoxaparin below 1.0 IU/ml and the absence of drug. The test provides information on the patient's citrated arterial whole blood response to enoxaparin by measurement of the clotting time using a factor Xa activated clotting method and should be interpreted in conjunction with other clinical data available to the clinician

The RapidPoint Enoxaparin (ENOX) test is a one-step dry coagulation method performed on the RapidPoint Coag analyzer. All of the components necessary to perform the assay, with the exception of patient sample, are included in the reaction chamber of the test card. In the ENOX test, factor X is rapidly converted to factor Xa by a specific factor X activator initiating the clotting process. Enoxaparin, from the patient's blood, complexes with antithrombin (AT), to inhibit factor Xa and lengthen the clotting time. Reported clotting times in excess of the assay cut-off indicate an enoxaparin concentration greater than or equal to 1.0 International Units per milliliter. The results generated by the ENOX test are indicative of the anticoagulant effect produced by enoxaparin in citrated arterial whole blood. The test card formulation contains purified Factor Xa activator, calcium, phospholipid and stabilizers. Paramagnetic iron oxide particles (PIOP) are included to provide an optical detection mechanism in the presence of patient sample.
