2021年8月10日 · In this review, we conclude that the 20WBCT is capable of detecting coagulopathy following snakebite with high specificity and acceptable sensitivity. Diagnostic test accuracy of the 20WBCT is improved when assessing for the presence of severe coagulopathy.

The 20-minute whole blood clotting test (20WBCT) has been used to detect coagulopathy following snakebite for almost 50 years. A systematic review and meta-analysis of the 20WBCT was conducted to evaluate the accuracy of the 20WBCT to detect coagulopathy, indicative of systemic envenoming.

In this review, we conclude that the 20WBCT is capable of detecting coagulopathy following snakebite with high specificity and acceptable sensitivity. Diagnostic test accuracy of the 20WBCT is improved when assessing for the presence of severe coagulopathy.

2019年3月27日 · The 20 min whole blood clotting test (WBCT20) is a simple bedside test recommended by World Health Organization (WHO) to assess hemotoxic envenomation and guide administration of polyvalent anti-snake venom (ASV). However, reliability and validity of this test has not been well documented in literature.

The 20-minute Whole Blood Clotting Test (20WBCT, also WBCT20) is a simple bedside procedure to assess coagulopathy following snakebite. However, it is not without its limitations.

The whole blood clotting test is a blood test used to check the coagulation mechanism in the blood following a snake bite. [1] . If the test is positive after a bite in South East Asia it indicates the snake was a viper rather than an elapid. [1] . It can also be used to assess the effectiveness of antivenin therapy. [2]

2023年6月26日 · Our findings show that the 20WBCT is a simple, cheap, and easily accessible bedside test with a high sensitivity for the detection of patients with VICC following carpet viper envenoming in North-eastern Nigeria.

2019年3月22日 · 世界卫生组织指南推荐的20分钟全血凝血试验（20'wbct）可能是国内最常用的床边筛查工具。 改良的 Lee 和 White (MLW) 方法给出了一个值，该值在连续执行时给出了凝血时间的...。

2025年3月6日 · TL;DR: The 20-minute whole blood clotting test is a simple bedside test to screen for and monitor coagulopathy in resource-limited settings and assess vital parameters and initiate resuscitation measures if the patient is clinically unstable with signs of bleeding, shock, paralysis, or respiratory distress.

2020年10月15日 · Twenty minute whole blood clotting test (20WBCT) is a useful and informative bedside test recommended by WHO for diagnosis of significant coagulopathy following snakebite envenoming since it to some extent predicts the need for anti-venom therapy.
