Algorithms that incorporate genetic information, such as one for measuring doses of warfarin, a blood-thinner, are often inappropriately calibrated for Africans.

包含遗传信息的算法往往不适合非洲人，比如用于测量血液稀释剂华法林剂量的算法。

Long-term treatment to prevent future thrombi from forming can include anticoagulant medications like warfarin or heparin, which inhibit the clotting cascade and prevent clot formation.

预防DVT的长期疗法包括华法林、肝素等抗凝药物的使用，可以阻断凝血反应。

This is a risk for people taking warfarin, especially in large doses, without an overlapping rapid-onset blood thinner such as heparin or low molecular weight heparin.

这在服用华法林的患者中存在风险，尤其是当大剂量使用且没有叠加使用如肝素或低分子量肝素等速效血液稀释剂时。

There are also acquired forms of protein C or S deficiency, like impaired production as seen in patients with liver disease or in patients taking warfarin, also called coumadin.

也有获得性蛋白C和S缺乏症，一种病因是蛋白产出受损，比如在肝病患者或服用华法林（也叫香豆素）的病人体内。

Finally, with protein C or S deficiency, there can be warfarin induced skin necrosis, which means tiny thrombi can form in the blood vessels of the skin, causing skin necrosis.

此外，患者身上还可能出现华法林导致的皮肤坏死，也就是说在皮肤血管中形成小血栓，导致皮肤坏死。

Since warfarin can lower the levels of protein C and protein S, it is very important that a patient does not take warfarin for at least 2-4 weeks prior to being tested for protein C or protein S deficiency.

由于华法林能够降低蛋白C和S的水平，所以在进行蛋白C和S缺乏症检查之前一定要确保患者至少在2-4周内没有服用过华法林。

Ibuprofen should also be avoided in patients who have a heart condition such as atrial fibrillation who are on blood-thinning agents such as warfarin, rivaroxaban, or apixaban, as ibuprofen or NSAIDs in general increase the risk of bleeding.

布洛芬也应避免用于患有心脏疾病（如房颤）并正在服用血液稀释剂（如华法林、利伐沙班或阿哌沙班）的患者，因为布洛芬或非甾体抗炎药通常会增加出血的风险。
