A CSF IgG index measures the levels of IgG in your cerebrospinal fluid. Normally you have a tiny amount of IgG in your cerebrospinal fluid. High levels of IgG may mean you have an infection or an inflammatory or autoimmune disease that involves your central nervous system.

Cerebrospinal fluid (CSF) is a clear fluid circulating in the intracranial and spinal compartments. Under normal conditions, the composition of CSF remains constant. However, in various neurological disease especially in acute conditions, the ...

Cerebrospinal fluid (CSF) IgG synthesis rate indicates the rate of increase in the daily CSF production of IgG in milligrams per day. A result greater than 12 mg/24 hours is elevated. A CSF index greater than 0.85 is elevated and indicative of increased synthesis of IgG.

Elevation of IgG levels in the cerebrospinal fluid (CSF) of patients with inflammatory diseases of the central nervous system (CNS) (multiple sclerosis [MS], neurosyphilis, acute inflammatory polyradiculoneuropathy, subacute sclerosing panencephalitis) is due to …

Cerebrospinal fluid (CSF) IgG synthesis rate indicates the rate of increase in the daily CSF production of IgG in milligrams per day. A result greater than 12 mg/24 h is elevated. A CSF IgG index greater than 0.70 is elevated and indicative of increased synthesis of IgG.

2024年5月15日 · The Cerebrospinal Fluid (CSF) Immunoglobulin G (IgG) Index is an essential diagnostic test used predominantly in neurology. It plays a crucial role in assessing the immune response within the central nervous system (CNS), particularly in diagnosing diseases like multiple sclerosis (MS).

正常情况下中枢神经系统每天可产生3mg 左右的IgG， 脑脊液IgG 指数是反映鞘内IgG产生速度的指标。 在某些疾病脑脊液单克隆IgG 的合成量与病情变化密切相关。 1. IgG 升高见于急性脑血管病、 脑血栓、 缺血性脑血管病、 90 ％急性感染性多发性神经根神经炎、 重症肌无力、 吉兰-巴雷综合征、 多发性硬化症、 神经性梅毒、 精神分裂症等；IgG 减少见于癫痫、 X线照射、 服用类固醇药物等。 2. IgA 升高见于脑血管病、 各种类型脑膜炎、 多发性硬化症急性期、 30％急性感染 …

髓鞘少突胶质细胞糖蛋白（mog-igg）的免疫球蛋白γ自身抗体与特定的神经系统综合征相关，最常见的是急性播散性脑脊髓炎、视神经炎和纵向广泛性横纹肌炎。

The level of CSF albumin is used as a reference to indicate whether an increase of the IgG is due to local secretion or to increased permeability of the blood capillaries. CSF IgG is frequently elevated in multiple sclerosis; elevations occur also in CNS syphilis, postvaccinial encephalitis, subacute sclerosing leukoencephalitis, and other ...

2024年12月4日 · The CSF Immunoglobulin G (IgG) Index is a specialized test that evaluates the levels of immunoglobulin G (IgG) in cerebrospinal fluid (CSF) relative to those in blood. This test provides critical insights into central nervous system (CNS) disorders, especially those involving inflammation or autoimmune activity, such as multiple sclerosis (MS).
