Serum copper is decreased in premature newborns and increased in newborns with hemolytic jaundice.

with the individual protein testing capacity of the WB. The assay can be tailored to the requirements of screening or confirmatory testing as well as to the needs of specific vaccine studies. Vaccine trials could benefit greatly from a PBA that differentiates protected from infected individuals. Because large-scale vaccine studies are likely to be conducted in settings where conditions may not permit easy handling of fresh blood specimens, the DBS technology constitutes an attractive alternative for specimen collection and the PBA appears to be well suited for this purpose. The HIV PBA offers substantial advantages over conventional immunoassays, but standardization , validation, and performance testing remain to be done before the assay can be used for clinical testing.
