一种针对犬心丝虫（犬恶丝虫）的诊断测试。

Vet Hum Toxicol. 1982 Feb;24(1):1-7.

Studies with a HI test for the detection of circulating antibody to the dog heartworm (D. immitis) are described. Natural as well as experimentally infected animals demonstrated the capability of detecting infestations before circulating microfilaria would be found and as early as 23 days after experimental infection with larvae.

本文描述了用血凝抑制（HI）试验检测犬心丝虫（犬恶丝虫）循环抗体的研究。自然感染和实验感染的动物均显示，该试验能够在循环微丝蚴出现之前，甚至早在幼虫实验感染后23天就检测到感染情况。
