Detection of HIV-specific antibodies forms the corner stone for laboratory diagnosis of HIV infections. Serologic methods are routinely used to determine whether a host is infected with HIV, to evaluate the status of infections, and to assist monitoring antiretroviral therapy. Primary diagnosis of HIV infection is commonly accomplished by serology via detection of HIV antibody using a screening...

BACKGROUND Although it is known that first degree relatives of celiac patients have an increased risk for celiac disease few studies are available on its incidence. We investigated the incidence of serologic conversion and of new cases of celiac disease among first degree relatives with negative results at a first screening. METHODS From a total of 634 first degree relatives of 186 biopsy-pro...

Syphilis is a notifiable and preventable disease, congenital syphilis more so. Consequently, attention has been recently focused on prenatal diagnosis of foetal syphilis by the use of ultrasonography apart from the conventional serologic screening. Congenital syphilis has not been reported from the Kingdom of Lesotho. We report the case of a 3.0 kg male neonate with florid joint and bone lesion...

background: celiac disease is one of the malabsorption syndromes leads to growth and development retardation in children. there is no test lonely can definitely diagnose celiac; however, the collection of clinical findings, serologic tests, intestinal biopsy, and response to treatment may diagnose it. although diagnostic value is variable in different studies, they are used a non-invasive and a...

The epidemiology and pathogenesis of CMV infections among pregnant women have been intensely studied over the last three decades. This paper highlights recent developments that make either universal or limited serologic screening for CMV during pregnancy potentially attractive. The developments include an understanding of the pathogenesis of CMV infections, a knowledge of high-risk women, the a...

A panel of 114 blood samples from chronic chagasic patients and nonchagasic patients was screened for Trypanosoma cruzi by xenodiagnostic, serologic, and polymerase chain reaction (PCR) amplification tests. Blood samples were preserved in a guanidine-EDTA buffer, and total blood DNA was isolated after chemical nuclease cleavage with 1,10-phenanthroline-copper ion and used as a template for PCR ...

Objective To review the evidence on benefits and harms of screening for celiac disease in asymptomatic adults, adolescents, and children 3 years and older for the US Preventive Services Task Force. Data Sources Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Coc...

OBJECTIVE The objective of this study was to compare the cost-effectiveness of 3 strategies of serologic enzyme-linked immunosorbent assay (ELISA) testing and post-exposure varicella zoster immune globulin (VZIG) prophylaxis for the prevention of maternal varicella pneumonia during pregnancy in patients with negative or uncertain histories of varicella infection. METHODS A decision tree was c...
