Product features: CoaguChek XS PT Test Test strips Intended use: Test strips for the quantitative in vitro determination of the prothrombin time of capillary whole blood or non-anticoagulated venous whole blood using a CoaguChek XS/XS Plus/XS Pro device. Suitable for self-testing. Also known as a Quick test or Quick value, or by the abbreviation PT. Test principle: Electrochemical measurement of prothrombin time after activation of blood coagulation with recombinant human thromboplastin. Each test strip contains a test pad with a prothrombin reagent. Once the blood is applied, the reagent dissolves and an electrochemical reaction takes place, which is converted into a coagulation time value. This value is displayed on the device screen in INR units.^1-2 Measuring range and therapeutic range: The measurement results on the CoaguChek XS/XS Plus/XS Pro device can be displayed in the following units: INR (International Normalized Ratio), % Quick, and seconds. The measurement ranges are as follows: 0.8–8.0 INR (5–120 % Quick). Your individual therapeutic range will be determined by your doctor. The mapping between INR and % Quick may vary slightly depending on the batch of CoaguChek XS PT test strips. Procedure for measurement results outside the therapeutic range: If the measurement results are unusually low or high, the test should be repeated. If the measurement result is still outside the therapeutic range specified by the doctor, the treating physician should be notified immediately and further (anticoagulation) measures discussed to prevent risks from excessive anticoagulation (risk of bleeding) or insufficient anticoagulation (risk of thrombosis). Guidelines for self-determination regarding physical therapy: If, in addition to treatment by a physician, the patient performs self-monitoring of PT (percutaneous glucose tolerance test), the following should be noted: Self-monitoring supports medical monitoring but cannot replace it. Self-monitoring provides the anticoagulated patient with greater confidence in their daily life. The measured results should be recorded in a diary (patient record) and regularly presented to the physician. This facilitates the physicians assessment of the effectiveness of the therapy. Sample material: Use only fresh capillary blood or venous whole blood without anticoagulants (heparin, EDTA, citrate, oxalate, or other substances). If using capillaries, please use only the special CoaguChek capillary tubes ([ref] 11621173). Storage and shelf life: Store between 2-30°C. If stored at room temperature or in a refrigerator, the test strips can be kept until the expiry date printed on the packaging or test strip container. Do not use test strips after the expiry date. Immediately and tightly close the tube after removing a test strip. This is necessary to prevent the remaining test strips from becoming unusable due to external factors such as humidity. Materials supplied: Test strips and 1 code chip Additional materials required: CoaguChek XS Plus device or CoaguChek XS Pro device or CoaguChek XS device CoaguChek XS PT Controls Lancing device, e.g. CoaguChek XS Softclix Lancets (CoaguChek Softclix Lancet or Accu-Chek Safe-T-Pro Plus) The CoaguChek XS Softclix lancing device was specifically designed for self-testing by the patient. It is not suitable for clinical use or for testing multiple individuals due to the risk of infection. Healthcare professionals performing tests on multiple patients must be aware of the potential risk of infection. Any object that comes into contact with human blood represents a potential source of infection. Source: Information from the package insert As of July 2018
