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8月1日 · Background: 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.

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.

Background: The 20-min whole blood clotting test (WBCT20) is widely used for the identification of coagulopathy in snake envenoming, but its performance in practice has not been evaluated. Aim: We aimed to investigate the diagnostic utility of the WBCT20 for coagulopathy in Russell's viper envenoming.

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 results of 2ml 20min WBCT was compared with the special Blood Coagulation Profile Test to assess the validity of WBCT20 in early detection of coagulopathy for consideration of ASV in vasculotoxic

2023年6月26日 · We conducted analysis of 20-minute whole blood clotting tests (20WBCT) performed on snakebite patients in Kaltungo General Hospital, Nigeria who presented within 24 hours of the bite and who brought a dead snake along for snake identification, and we assessed its ability to detect venom induced consumptive coagulopathy (VICC) (defined as an INR ...

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趋势，研究人员假设与 20'WBCT 相比，它是连续评估受害者的更好工具。

2021年8月10日 · Background: 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.

aim is to compare WBCT at 20 and 30 minutes as a better predictor of venom-induced coagulopathy and to determine its sensitivity and specificity. Methods: In this study, for each patient before giving ASV 2ml venous blood was drawn for 20 minutes WBCT and 30 minutes
