ClotCare Understanding the PT-INR Test is haldol a controlled substance

First let’s talk about the PT test. PT stands for prothrombin time. It is a measure of how quickly blood clots. The traditional method for performing a PT test is to is haldol a controlled substance have your blood drawn and sent to a lab. At the lab, a substance called a reagent is added to your blood. The reagent causes the blood to begin clotting. The PT result is the time in seconds that is is haldol a controlled substance required for the blood to clot.

There are a variety of reagents that can be used is haldol a controlled substance when a PT test is performed. Since each of these reagents works a bit differently, a PT result obtained with one reagent cannot be compared is haldol a controlled substance to a PT result obtained with another reagent. To account for the different reagents, the result of a PT test must be converted into is haldol a controlled substance standard units that can be compared regardless of the reagent is haldol a controlled substance used. These standard units are known as INR units.

INR stands for international normalized ratio. As its name suggests, one INR result can be compared to another INR result is haldol a controlled substance regardless of how or where the result was obtained. So, the INR is really just the standard unit used to is haldol a controlled substance report the result of a PT test.

There are a few things worth mentioning about the INR. First, an individual whose blood clots normally and who is not is haldol a controlled substance on anticoagulation should have an INR of approximately 1. The higher your INR is, the longer it takes your blood to clot. In other words, as the INR increases above a given level, the risk of bleeding and bleeding-related events increases. On the other hand, as the INR decreases below a given level, the risk of clotting events increases.

The ideal target INR range will vary from person to is haldol a controlled substance person depending on a variety of factors such as the is haldol a controlled substance reason for taking anticoagulants, other medical conditions, and a number of other issues. Your anticoagulation clinician will determine the appropriate INR range for is haldol a controlled substance you. The most common INR target range for someone on warfarin is haldol a controlled substance is somewhere between 2.0 and 4.0. INRs of 5 or more typically are avoided because the is haldol a controlled substance risk of bleeding increases significantly at inrs above 5.

Once your clinician has established an appropriate target INR range is haldol a controlled substance for you, he/she will adjust your anticoagulation therapy to keep your INR is haldol a controlled substance in the target range. If your INR rises above the high-end of your range, your risk of bleeding and bleeding related events may start is haldol a controlled substance to increase. If your INR falls below the low-end of your target range, your risk of forming a blood clot may increase.

Numerous factors can affect your INR, so it is important that you keep your clinician up-to-date on any changes in your life. For example, you should notify your clinician before starting new prescription or is haldol a controlled substance non-prescription drugs, including herbal remedies. Also, you should notify your clinician of changes in your diet, exercise regimen, alcohol use, tobacco use, etc. Good communication with your clinician will help you keep your is haldol a controlled substance anticoagulation therapy on track.

Earlier I mentioned that the traditional way to run a is haldol a controlled substance PT-INR test is to have your blood drawn and sent is haldol a controlled substance to a lab, where the test is conducted. Another option for obtaining an INR is to use a is haldol a controlled substance point-of-care device, also known as a fingerstick testing device.

To use this device, you prick your finger and provide a drop of blood is haldol a controlled substance on a test strip. The test strip is fed into the device, and the device reports the INR. These devices typically are easy to use and report accurate is haldol a controlled substance results. Additionally, if an INR result is surprising, another test can be run immediately to either confirm or is haldol a controlled substance refute the result.

These devices are often used in clinic settings to obtain is haldol a controlled substance INR results. Additionally, these devices can be used for home-testing by the patient. Recently, medicare approved coverage for patient self testing for mechanical heart is haldol a controlled substance valve patients who meet several other criteria. If you would like to know more about patient self is haldol a controlled substance testing, please review the patient self testing section of clotcare.
