由医学专业人士埃琳·达维茨基及其联合创始人开发的LymeAlert——首款家用蜱虫莱姆病检测工具，将于8月上市，售价约50美元。[1]该工具能够检测蜱虫体内引起莱姆病的病原体伯氏疏螺旋体，使用者只需用镊子移除蜱虫后放入检测套件，约15分钟即可获得结果，操作方式类似于妊娠试纸或新冠检测，测试结果以两条线表示阳性、一条线表示阴性。[1]
这一工具的推出旨在解决传统邮寄蜱虫检测方式的延迟问题。[1]美国疾病控制中心建议在蜱虫叮咬后72小时内单次服用200毫克强力霉素作为预防性用药，但传统检测结果往往因邮寄耗时而错过这一预防窗口。[1]另一方面，早期血液检测在蜱虫叮咬后30天内的漏诊率达64%-78%，因为蜱虫需要附着36至48小时才能传播疾病。[1]
莱姆病在美国具有较高发病率。[1]每年约有476,000名患者因莱姆病接受治疗，超过3100万美国人（约十分之一）每年被蜱虫叮咬。[1]值得注意的是，疾病控制中心不建议对从人或动物身上移除的蜱虫进行检测，因为可能出现假阴性和假阳性。[1]
LymeAlert, a home-based diagnostic tool for detecting Lyme disease in ticks, will become available in August at approximately $50 per test [1]. Developed by medical professional Erin Davitzky and her co-founders, the kit enables users to check ticks for Borrelia burgdorferi, the bacterium responsible for Lyme disease, within about 15 minutes of removal—similar to how pregnancy or COVID-19 tests function [1]. The test displays two lines for a positive result and one line for a negative result [1].
The innovation addresses a critical gap in disease prevention. Approximately 476,000 Americans seek treatment for Lyme disease annually, and more than 31 million people in the United States—roughly one in ten—experience tick bites each year [1]. The CDC recommends taking a single 200-milligram dose of doxycycline within 72 hours as preventive treatment [1]. However, mail-in tick testing delays often cause patients to miss this critical window, while early blood tests still miss 64 to 78 percent of early-stage cases within 30 days of a tick bite [1]. Since ticks require 36 to 48 hours of attachment to transmit disease, immediate testing of removed ticks provides a practical opportunity for rapid decision-making [1].
The CDC does not recommend testing ticks removed from people or animals due to the risk of false negatives and false positives [1]. Nevertheless, LymeAlert's at-home approach offers patients a faster, more accessible option than existing diagnostic methods for determining whether prophylactic medication is warranted.
