1. Introduction The Coag-Sense® Prothrombin Time (PT)/INR Monitoring System Intended Use The Coag-Sense Prothrombin Time (PT)/INR Monitoring System is an in vitro diagnostic device that provides quantitative prothrombin time (PT) results, expressed in seconds and International Normalized Ratio (INR) units. It uses fresh capillary whole blood. It is intended for use by health care professionals at the point of care to monitor patients who are on warfarin-type (coumarin) anticoagulation therapy.
Anticoagulation Medication: Oral anticoagulation medications, are typically prescribed to patients to avoid unwanted clots. The patient’s blood clotting time must be monitored to ensure that their dosage is correct.
2. System Description The Coag-Sense Prothrombin Time (PT)/INR System is used for quantitative measurement of INR (International Normalized Ratio) based on a Prothrombin Time (PT) response to monitor the effect of therapy with vitamin K antagonists like Coumadin® (warfarin). The system uses fresh, capillary whole blood.
Meter: The meter has a TFT color LCD Touch screen that shows results, information, icons and results recalled from memory. To select an option, gently click on display button. There are three touch buttons, Cancel or Previous Screen Button, Home Screen Button and View Button Screen for the Guided User Interface (GUI) operation. The Power ON/OFF button is located on the right side of the meter.
PT result that adjusts for sensitivity differences among different PT/INR systems. Control Strips and Control Activation Solution Quality control is an important part of PT testing to verify the integrity of the performance characteristics of the testing system. The Coag-Sense Meter has been designed with multiple internal systems to ensure proper system function.

4. Performance Characteristics Expected Values: Results are reported in INR units equivalent to the plasma reference method. For PT testing, variations in the source of thromboplastin may cause some differences in results between methods. It is recommended that the same method be used to monitor the anticoagulation therapy over time. Measuring Range: INR 0.8 to 8.0 Normal Range: The following example represents a common normal range for the Coag-Sense PT/INR system. INR: 0.7 to 1.2 PT: 8.0 to 15.
5. Warnings and Precautions This test system is not recommended for patients who have recently taken or are currently taking any type of Heparin anticoagulants. The system should also not be used to monitor patients on direct oral anticoagulants (DOACs) including Factor Xa and Direct Thrombin inhibitors. Test Site and Blood Sample • The Coag-Sense PT/INR system is for in vitro diagnostic use only. • The Coag-Sense meter will not produce a result if the test strip is past its expiration date.
If any alcohol remains (or is re-introduced) on the finger, it may cause unreliable results. • Do not use wipes containing chlorhexidine gluconate, as it may produce unreliable results. • The quality of fingerstick and the sample delivery technique are important to the test results. If there is a question about the sample or sample collection, obtain a new strip, repeat the fingerstick on a different finger, and test again.
• Do not pull the strip out while the wheel is spinning. STOP the test, meter will display “Test Cancelled, Remove Strip’ The strip should be removed at this time only. • Store and use the Coag-Sense PT/INR system following the instructions in this manual. • This equipment is tested to meet the limits for medical devices, which are designed to provide a reasonable protection against harmful interference when the equipment is operated in a clinical or home environment.

The CoagSense meter can be connected to a Local Area Network (LAN) via either a direct Ethernet connection or wirelessly using Wi-Fi. If this meter is connected to a local area network, the network must be protected against unauthorized access. It must not be linked directly to any other network or the Internet.
15. Meter Software Update When connected to the Internet, the Coag-Sense meter can check for the availability of meter software updates which can be downloaded. If the meter is not continuously connected to the Internet, you should make it a practice to periodically connect the meter to the Internet to check for software updates. If a critical update is available, the meter may require the installation of an update prior to proceeding with testing.
16. Battery The Coag- Sense meter has a factory installed Rechargeable Lithium Polymer Battery, that charges when the power adapter (provided with the meter) is plugged into the wall socket. A charged battery (6 hours to fully charge) can run approximately 200 tests. Please be aware that battery life may be affected by many factors such as operating conditions (e.g. ambient temperature), frequency of use, and test duration. Note: The Battery is not User replaceable.
17. Cleaning and Disinfecting the Meter No maintenance is required other than routine cleaning and/or disinfecting. When the power is off and the USB cable is not connected, the meter housing can be cleaned and disinfected. Wipe all exposed surfaces with Healthcare Bleach Germicidal Wipes containing Sodium Hypochlorite (EPA No. 67619-12) for a contact time of 1 minute to pre-clean blood and other body fluids.
WARNING: Do not put the meter in liquid. Do not allow liquids to get inside the meter or into any of the connectors or plugs on the meter. If you suspect any physical damage or deterioration of the meter (such as cracking or gross distortion), or if the meter does not turn on after cleaning, call Technical Support. Always refer to local, state and federal disinfecting guidelines.
18. Troubleshooting The Coag-Sense Meter continually checks its systems for unexpected conditions. These may arise because of defective components or consumables, environmental factors or due to user handling and procedure errors. This section details how to resolve most problems that you might encounter. If you have any questions or problems during the troubleshooting process, note the display wording and contact Technical Support at 866-903-0890 or email techsupport@coagusense.com.
