You can find out if a pharmacy near you offers CPAMS (external link). Your GP is also informed of the INR result, as they have overall responsibility for your care. The pharmacist measures your INR levels using a finger prick test and can tell you the dose of warfarin to take. Some pharmacies in New Zealand have a warfarin service called the Community Pharmacy Anti-Coagulation Management Service (CPAMS). Your INR result will be passed onto your GP. This sample is then sent to a laboratory for analysis. Blood collection centreĪcross New Zealand there are blood collection centres where a phlebotomist (someone who is trained to take blood) collects a blood sample from your vein. If you are not on anticoagulant therapy, it may be an emergency where there is a liver failure and it may even require a liver transplant.In New Zealand you can get your INR test done at a blood collection centre (such as MedLab) and some community pharmacies. In addition, he may prescribe you vitamin K, clotting factor concentrate or fresh frozen plasma to avoid prolonged bleeding time. If you are taking anticoagulant medication, you should visit your doctor immediately to reduce the dose or suppress it completely. If you are not on anticoagulant therapy, values are very high and it may be due to a liver disease that requires immediate attention. There also many drugs (antibiotics for example) that may interfere the effect of anticoagulants. In addition, it may prescribe you small doses of vitamin K. If you are taking anticoagulant medication, you should reduce the dose or stop it according to your doctor prescription to avoid prolonged bleeding. Marked INR increase (4.5 - 7 in adults):.In people not on anticoagulant therapy, it may be due to a liver disease or disseminated intravascular coagulation ( DIC). If you are taking anticoagulant drugs (warfarin) you should visit your doctor to adjust (reduce) the dose and avoid an INR over 3 (or 3.5 if you have a mechanical heart valve). Moderate INR increase (3 - 4.5 in adults):.Therefore, these values are considered to in the appropriate range. In patients under anticoagulant treatment, those who are being treated with warfarin (Coumadin) or acenocoumarol, the INR should be 2 to 3. INR is only recommended for patients under anticoagulant therapy. Anyway, it is better to use prothrombin time (PT) for this matter. It may be due to a liver disease or vitamin K deficiency. These values in people not under anticoagulant treatment are over the normal range and a visit to your doctor is recommended. In people under anticoagulant therapy with warfarin (Coumadin) or acenocoumarol, values of INR over 3 mean that the dose of anticoagulants prescribed is excessive and should be reduced. In healthy people not under anticoagulant therapy, a high INR value may suggest a liver disease, vitamin K deficiency or disseminated intravascular coagulation ( DIC). The objective of anticoagulant therapy is to prevent cardiovascular disorders and thrombosis. INR is usually used to monitor the dose of patients under anticoagulant therapy. Usually, laboratory changes thromboplastin and/or equipments used to calculate PT with has a direct impact on prothrombin time, but the INR remains constant even with such changes. The major advantage of the INR system is that it helps alleviate confusion in the interpretation of prothrombin time (PT) results. PT is one of the most important parameters measured in the coagulation screen section of a blood test. INR is close related to the prothrombin time (PT). When there is a hemorrhage, the clotting process is activated to stop the bleeding. A high INR (International Normalized Ratio) value shows an increase in the time necessary to complete the clotting process.
