Neuropathy refers to the injury or dysfunction of one or more nerves, which results in numbness, tingling, muscle weakness and discomfort in the nerves affected part. Neuropathies often arise from the hands and feet, sometimes other parts of the body also affected. Peripheral neuropathy refers the injury or dysfunction of the peripheral nerves.  Peripheral neuropathy might be acute or chronic, and sometimes it is reversible. Neuropathy induces a series of complications in the health and develop the symptoms of those issues. Biochemical markers are increasingly used for the early diagnosis of the neuropathy. In addition, such markers may provide additional information for understanding the pathology of disease. Several markers such as a tau protein (tau), Phospho-tau181 (p-tau181), Phospho-tau217 (p-tau217), neurofilament light chain (NFL) and so on have been identified to be associated with the neuropathy disorder. Detecting the quantity of these marker proteins from different samples may benefit from ELISA, Lateral flow immunoassay (LFIA), colloidal gold immunochromatographic assay, Chemiluminescent immunoassay (CLIA), turbidimetric inhibition immuno assay (TINIA), immunonephelometry and POCT.

Genemedi supplies antibodies and antigens for Neuropathy testing for a wide selection of choices (please see below).

GeneMedi's p-tau217/Tau and p-tau181/Tau antibody pairs show good performance in serological diagnosis of Alzheimer's Disease (AD) blood test



Established biomarkers for Alzheimer’s disease, including beta-amyloid (Aβ) and tau. Compared with CSF-based measurements, blood-based biomarkers have the potential to be deployed widely due to the lower costs and less invasiveness. Decreased beta-amyloid 42/beta-amyloid 40(Aβ42/Aβ40) ratio and increased p-tau217 and p-tau181 were associated with subsequent Alzheimer’s disease diagnosis1. Both p-tau217 and p-tau181 had an excellent diagnostic performance for differentiating patients with Alzheimer’s disease syndromes from other neurodegenerative disorders. Besides, P-tau217 was a stronger indicator than p-tau1812.

GeneMedi's p-tau217/Tau and p-tau181/Tau antibody pairs show good performance in diagnosis of Alzheimer's Disease blood test. Recently, Eli Lilly's P-tau217 Serological Test also showed high accuracy in diagnosis of Alzheimer's Disease, which was published in JAMA.
