A pilot study of dried blood spot testing for HIV antibody in neonates

An unlinked anonymous HIV antibody study of neonates, using surplus dried blood spots on Guthrie cards, was introduced as a means of estimating the prevalence of HIV infection in childbearing women. From March 1990 to February 1992, blood spots from 14,520 infants were tested for anti-HIV, using an HIV IgG antibody capture particle-adherence test; only one sample gave a confirmed positive reaction. This type of study involves no interference in routine care and can be operated without difficulty in a district general hospital setting where neonatal metabolic screening is performed.
