...To help clinch a diagnosis of MS, clinicians often test the spinal fluid for elevated levels of IgG. Since everyone makes IgG as a part of normal immune function, scientists have to assess cerebrospinal IgG levels using an index that also factors in the amount of IgG in the patient's blood and the integri...Europe struggles to meet the challenges posed by PGD patients travelling abroad
