EB病毒衣壳抗原(igG)、抗EBV核抗原(EBVNA一igG)呈阳性，即提示存在既往有EB病毒感染，但要明确目前的身体的情况，需要配合,igM等其他的结果分析，以明确后续的方向。

2024年4月10日 · Epstein-Barr virus (EBV), also known as human herpesvirus 4, is a gamma herpes virus that occurs only in humans. Laboratory testing can help distinguish whether someone is susceptible to EBV infection or has a recent or past infection. EBV antibody tests are not usually needed to diagnose infectious mononucleosis.

2019年6月11日 · The EBV (Epstein Barr) Nuclear Antigen Antibodies, IgG test looks for a type of antibody which the body typically develops in response to Epstein-Barr Virus. EBNA antibodies usually appear 2-4 months after infection and persist for the life of the person. This test is usually performed to establish a past infection with EBV.

EBV-NA-IgG，是EB病毒核心IgG抗体，这个抗体一般在急性感染出现症状后6-12周开始出现，并可以持续终身。 但如果出现阳性，则可有助于排除急性感染。 简单小结，如果是IgM抗体阳性，则代表近期感染，而如果是IgA阳性，则反映近一年有过感染，但IgA长期阳性，则可能与鼻咽癌发展相关；而IgG阳性则反映既往感染过，其阳性可持续终身。 目前临床上EB病毒抗体5项检测（VCA-IgA、EA-IgA、NA-IgA、Zta-IgA、Rta-IgG）用于鼻咽癌筛查，首次发现抗体阳性时，一般建 …

The study investigated the distribution of Epstein-Barr virus (EBV) EA-IgA, VCA-IgA, and EBVNA-IgG antibodies in a local population of Wuhan, China. Chemiluminescence immunoassay (CLIA) was used to detect EBV EA-IgA, VCA-IgA, and EBVNA-IgG antibodies in 972 subjects undergoing physical examination i …

Epstein–Barr nuclear antigen 1 (EBNA1) is a multifunctional, dimeric viral protein associated with Epstein–Barr virus (EBV). [1] . It is the only EBV protein found in all EBV-related malignancies. [2][3] It is important in establishing and maintaining …

EBV nuclear antigen (EBNA) IgG antibodies do not appear during the acute phase of infection but appear around 2-4 months after initial clinical presentation and typically persist for life. The presence of EBNA IgG antibodies in healthy individuals typically indicates past immunological exposure to EBV; however, false positive results can occur.

2024年10月10日 · EB病毒是一种广泛存在于人群中的病毒，EB病毒核心抗原IgG大于600U/mL，意味着体内针对EB病毒核心抗原的IgG抗体水平显著升高，结果可能表明个体存在既往感染、当前感染、疾病状态等问题。 1、个体差异与检测误差： 不同个体对EB病毒的免疫反应存在差异，可能导致IgG抗体水平升高。 此外，检测方法、试剂等因素也可能影响检测结果，此时可以定期复查此指标，一般能够恢复正常。 2、既往感染： EB病毒感染后，即使病毒被清除，IgG …

2024年5月31日 · EB病毒EBNA-IgG主要是针对EB病毒核心抗原（NA）所产生的抗体，大于600U/mL表示可能存在既往感染、正在感染、疾病状态、个体差异、检测误差等，如有疑虑或 …

A positive EBVNA IgG result indicates infection more than six weeks previously A positive EBV VCA IgG result indicates infection at some time An EBV IgM is performed on all children under 16 years
