Newborn screening specimens are now tested for exposure to HIV using a new first-tier HIV screening immunoassay and a new second-tier HIV-1 / HIV-2 supplemental immunoassay.
This new assay has several benefits including the ability to identify newborns exposed to HIV-2.
More information is available in the letter to health care providers and on the Screened Disorders page under Human Immunodeficiency Virus.
