Complete evaluation of cerebrospinal fluid proteinogram represents a routine request of the clinician in the analysis of CSF in the Czech Republic. It comprises the measurement of concentrations of acute phase proteins (CRP, orosomucoid, haptoglobin, transferrin, prealbumin), immunoglobulins (IgG, IgA, IgM), compressive markers (albumin, fibrinogen), markers of CNS tissue destruction (apolipoproteins A-I, A-II, Apo B), complement components (C3, C4), alpha-1-microglobulin, beta-2-microglobulin, and proteinase inhibitors (alpha-1-antitrypsin, antithrombin III). Therefore, 19 CSF proteins of precisely verified clinical relevance are routine parameters for the assessment of the functional state of the blood-CSF barrier, presence of the intrathecal synthesis of immunoglobulins, inflammatory changes and verification of CNS tissue destruction. Evidence of these clinically relevant and independent parameters enabled the detection of the presence of autoimmune and neuroinfective diseases of CNS, even in clinical cases where the basic CSF parameters do not express relevant changes, or they are of a bordering or non-specific character. Clinically typical and the most significant abnormalities in the CSF proteinogram represent themselves a new access to a contemporary CSF analysis. Despite the fact that assessment of CSF proteins and their analysis is quite a difficult field in laboratory medicine, it is now routinely requested and routinely performed in the Czech Republic.
