 Unlike ELISA testing for HIV-antibodies in the blood, which may be transmitted to infants in pregnancy independently of the virus itself, dried blood spot testing can be used to detect genetic material of the actual virus, thereby avoiding the likelihood of a false positive result.Dried blood spot testing for HIV is not considered sensitive enough for diagnostic testing, but may be useful in estimating prevalence of HIV through surveillance.DBS specimens also pose less of a biohazard risk to handlers, and are easier to transport or store than liquid blood specimens.
