Abstract:
The invention relates to an improved assay for detecting antibodies in a tissue sample from individuals who test seronegative by conventional assay techniques, thus aiding in the diagnosis of possible pathogenic infections. Specifically, the invention relates to improved assay methods and kits that enable efficient detection of antibodies against a viral infection.
Abstract:
The present invention provides a method for determining the time of infection, and a method for determining if a microbial infection is in the early stages comprising the step of determining the ratio of in vitro stimulated anti-microbial immunoreactivity and un-stimulated anti-microbial immunoreactivity in blood samples from said subject and related kits.
Abstract:
The present invention provides a method for determining the incidence of human immunodeficiency virus (HIV) infections in a population comprising comparing the anti-HIV antibody levels of in vitro stimulated tissue samples to those of un-stimulated tissue samples from individual members of said population and related kits. The present invention also provides a method of determining the distribution of recent, non-recent, and late stage human immunodeficiency virus (HIV) infections in a population comprising comparing the in vitro stimulated anti-HIV immunoreactivity and un-stimulated anti-HIV immunoreactivity in tissue samples from individual members of said population and related kits.
Abstract:
This invention relates to methods that enable the detection of antibodies against a latent infection, a chronic infection, a re-infection, and/or a breakthrough infection; enable the diagnosis of a latent infection, a chronic infection, a re-infection, and/or a breakthrough infection; and increase low anti-viral antibody levels, and a kit for the detection of virus-specific antibodies expressed at low levels.
Abstract:
The present invention relates to an improved method for detecting antibodies to a hepatitis virus in a tissue sample from individuals, which can reliably detect antibodies in recently infected individuals and which provides much lower false positive results in individuals that have cleared their hepatitis infections. More particularly, the present invention relates to an improved method and kit which utilizes an activator of (i) hepatitis virus-primed lymphocytes, (ii) memory cells specific for said hepatitis virus, (iii) hepatitis virus-specific antibody production, or (iv) a combination thereof in a tissue sample to stimulate the production of antibodies from newly primed B cells, if present.

Abstract:
Esta invención se refiere a métodos que permiten la detección de anticuerpos contra una infección latente, una infección crónica, una re-infección, y/o infección de afloramiento; que permiten el diagnóstico de una infección latente, una infección crónica, una reinfección, y/o infección de afloramiento; y que aumenten los bajos niveles de anticuerpo antivirales, y a un equipo para la detección de anticuerpos de virus específico expresados a bajos niveles.
Abstract:
La presente invención proporciona un método para determinar la incidencia de infecciones por virus de inmunodeficiencia humana (VIH) en una población, que comprende comparar los niveles de anticuerpo anti-VIH de muestras de tejido simulado in vitro con aquellos de muestras de tejido no estimulado de miembros individuales de dicha población y equipos relacionados. La presente invención también proporciona un método para determinar la distribución de infecciones por virus de inmunodeficiencia humana (VIH) de etapa reciente, no reciente, y tardía en una población que comprende comparar la inmunoreactividad anti-VIH estimulada in vitro y la inmunoreactividad anti-VIH no estimulada en muestras de tejido de miembros individuales de dicha población y equipos relacionados.
