1.Some of these activated B-cells mature directly into plasma cells and produce IgM antibodies.

其中一些被激活的B细胞直接成熟分化为浆细胞并产生IgM抗体。

2.Immunoassays may detect IgG antibodies, the most abundant class, and IgM antibodies, the type that's first produced in response to a new infection.

免疫测定可以检测 IgG 抗体（最丰富的一类）和 IgM 抗体（应对新感染而首先产生的抗体）。机翻

3.And on immunofluorescence, there might be nonspecific focal deposits of IgM and complement proteins, and these get trapped in the areas of hyalinosis, but these isn't always seen.

在免疫荧光电镜下，可能有非病灶IgM和补体蛋白积；这些积局限样变区域，但不总是出现。

4.These centroblasts have a rearrangement of their immunoglobulin genes, and some of them undergo a class switch where they change from producing IgM antibodies to producing IgG or IgA antibodies.

这部分中心母细胞的免疫球蛋白基因发生了重排，其中的一些会经历Ig类别转换，从产生IgM变成产生IgG或IgA。

5.The diagnosis of west nile virus is made by detecting about four times the normal amount of IgM in the serum or CSF using an immunoassay test that's specific to the virus.

西尼罗河病毒的诊断基血清或脑脊液免疫检测抗体升高为正常水平4倍以上。

6.The presence of IgM antibodies suggests a recent infection, but since it can take the body over a week to produce a detectable amount, they're unreliable in diagnosing current infections.

IgM 抗体的存在表明近期感染，但由身体需要一周以上的时间才能产生可​​检测的量，因此它们在诊断当前感染方面并不可靠。机翻

7.So combining IgG or IgM, a positive on either and looking at just 20 days or more of having illness you can see that only one test actually captured everybody, that was the test from BioPerfectus.

因此结合IgG或IgM，任何一个呈现阳并且只看20天及以上的患病情况，你会发现只有一个测试真正检测出了每个病例，那就是来自BioPerfectus（江苏硕世）的测试。
