What is the difference between CMV IgG and IgM tests? When screening for CMV, there are two test types: The CMV IgG test indicates previous exposure to CMV The CMV IgM test indicates a recent or current CMV infection If the CMV IgM comes back positive, all semen vials are destroyed. W...
Positive predictive valuePregnancyUltrasound abnormalitiesClinical signsBackground Diagnosis of Cytomegalovirus (CMV) primary infection during pregnancy or in immunocompetent patients relies on serology with detection of specific CMV-IgG and IgM. In case of positive CMV-IgM in pregnant women, CMV-IgG ...
Results The positive detection rates of urine HCMN‐DNA and serum HCMV‐IgM were respectively 30 . 72% and 34 .93% (P>0 .05);suspected infection rate had no gender difference (P>0 .05) ,there was age differences in urine HCMN‐DNA and serum HCMV‐IgM detection (P<0...
其中40例CMV IgM抗体为阴性,40例CMV IgM抗体为阳性。CMV IgM阴性与阳性者AI值与CMV IgG抗体亲和力比较,差异均有统计学意义(P<0.05)。结论:在对CMV原发性感染诊断过程中,大部分CMV IgM抗體阳性者并非近期原发性感染,不能根据单一的血清学检测进行诊断,CMV IgM抗体检测联合IgG抗体亲和力分析有助于对CMV原发性感染...
Positive IgM results to) Cytomegalovirus (CMV) are indicated of a primitive or repeated infection. Study of Prevalence and Some Immunological Characteristics of Cytomegalovirus Infections among Pregnant Women (11) found no difference in CMV seropositivity rate between patients with atherosclerotic aorta ane...

CMV IgM positive sera should be tested with supplementary assays to dif-ferentiate primary from non-primary infection 2 . A new, promising microparticle enzyme immunoassay was recently developed using recombinant CMV antigens derived from portions of four structural and nonstructural proteins of CMV. ...
Reactivation of the virus is not uncommon, sometimes occurring with viremia and a positive IgM result in the presence of IgG antibody. This usually is observed during intercurrent infections or at times of patient stress. The clinical significance, time course, and natural history of reactivation ...
