CSF levels of HVA (homovanillic acid), MHPG (3-methoxy-4-hydroxyphenylglycol), and 5-HIAA (5-hydroxyindolacetic acid). Fibroblast assays: Neopterin (FB): synthesis of neopterin in cytokine stimulated fibroblasts; Biopterin (FB): synthesis of biopterin in cytokine stimulated fibroblasts; GTP-CH (FB): GTP cyclohydrolase enzyme activity in fibroblasts. NA, not available. Control values for monoamines are age adjusted.
