以血凝实验微量法测定其滴度和活性。
还可以抑制血小板活性因子从而减少血凝，稀释血管及微血管，并阻碍巨噬细胞释放趋化及致炎介质。
They also inhibit platelet activation factor and thereby reduce thrombosis, dilate arteries and capillaries, and block the release of chemotactic and inflammatory mediators from phagocytes.
结果：血凝滴度实验表明，在对甲型流感病毒的直接作用、治疗作用和预防作用3方面大多数板蓝根和大青叶有效，但各种质药材样品抗病毒活性的有无及强度有明显差异。
Results: According to hemagglutination titer, it was proved that most of Radix Isatidis and Folium Isatidis were effective to influenza a virus in 3 aspects: direct, therapeutic and preventive action.
