WebObjective: Measurement of human chorionic gonadotropin (hCG) and α-fetoprotein (AFP) in cerebrospinal fluid (CSF) can aid in the diagnosis of germ cell tumors (GCTs). Matrix effects can influence test results when alternative sample types are used, therefore, alternative sample types should always be validated before clinical use.

WebApr 9, 2024 · Alpha-Fetoprotein (AFP) is a glycoprotein with a molecular weight of 70 kDa. It has a single polypeptide chain and around 5% of carbohydrates. Alpha-Fetoprotein (AFP) is synthesized in large quantities by the fetal yolk sac and liver during embryonic development. It is the major protein in fetal circulation. WebAbstract We report a retrospective study on serum and cerebrospinal fluid (CSF) alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (betahCG) determination in a series of 30 patients bearing intracranial germ cell tumors. At diagnosis five patients had high serum and CSF AFP levels.
Webb. CSF should ideally be collected 3-8 days after onset. CSF obtained less than 3 days after onset of symptoms will be accepted, however, if non-reactive, the test does not rule out WNV infection and a serum specimen obtained 8 days after onset will be requested. 2. Specimens should be refrigerated and transported cold (on regular ice packs). Avoid WebCSF AFP in infants who did not have malignancy in order to determine its reference intervals. Methods AFP was measured in the CSF and/or plasma in 128 infants. Of these, 91 infants had CSF AFP measurements, 94 infants had plasma AFP measurements and in 60 infants AFP concentrations were determined in paired CSF and plasma samples.
