INR value
(International normalized ratio, Quick’s value, Quick’s test)
| Material: | 1 ml citrate plasma (Stability in citrate plasma at room temperature: 24 hours, this means that the blood sample can be taken in the evening and sent to the laboratory for testing the next day). Please do not store at 4°C (danger of factor VII-cryo activation, which in turn leads to false-normal Quick’s values/INR-values) |
| Methods: | Koagulometrie → Koagulometrie | Reference range | 70 – 120 % (INR 0,9 – 1,26) Therapeutic range in case of oral anticoagulation with vitamin K antagonists (Marcumar®, Warfarin®, Sintrom®)
Secondary prophylaxis after thromboembolic event: INR 2,0 – 3,0 Atrial fibrillation: INR 2,0 – 3,0 Mechanical heart valve: INR 2,0 – 3,0, if applicable 2,5 – 3,5 (i.e. mechanical double valve) |
| Indication |
|
| Please note | The INR-value can only be assessed in the stable phase of oral anticoagulation. During the introduction phase of anticoagulation treatment, the INR-value is not meaningful.
Antibiotics may influence the INR-value.
According to the Deutsche Gesellschaft für Ernährung e. V. (DGE- German society for nutrition), patients under anticoagulation treatment are not required to adhere to a specific diet. There is no need to relinquish vitamin K rich foods. Recommendations for a constant, varied and wholesome nutrition apply.
When taking DOACs (Dabigatran, Rivaroxaban, Apixaban and Edoxaban), there may be a decreased Quick’s value, there is no dose-effect-relation. It is not possible to rule out relevant remaining DOAC-concentrations by establishing the Quick’s value.
Should you have any further questions regarding the introduction of oral anticoagulation, our clotting consultation can be contacted every Tuesday between 1100 and 1200 hours under the telephone number 05222 8076-201. |
