To the Editor.— Definitive diagnosis of typhoid fever rests upon isolation of Salmonella typhosa. Pending results of isolation procedures, preliminary serology tests are widely used; the Widal reaction being the preferred test. 1,2,3 Despite difficulty with the interpretation of the Widal reaction, it is generally thought that a significant O antigen ...

Massive transfusion of low‐titer cold‐stored O‐positive whole blood in a civilian trauma setting
Transfusion, 2018Based on the improved outcomes achieved with fresh whole blood in cases of military trauma as well as with 1:1:1 transfusion strategies for massive traumatic hemorrhage in civilian settings, there has been resurgent interest in using whole blood for ...

Antibody titers in rabbits immunized with glucagon conjugated to albumin using difluorodinitrobenzene rose rapidly. Under conditions of immunoassay, less than 2 nl of serum from two of four animals and approximately 4 nl from the other two was required to bind 50% of the 10 pg of [125I]iodoglucagon 100 days after immunization.

Determination of the Specific Antibody Titer
Current Protocols in Molecular Biology, 2000AbstractThe amount of specific antibody present in polyclonal antiserum, ascites fluid, or hybridoma supernatant can be quantitated by either solid‐phase radioimmunoassay (RIA) or by direct ELISA. In the solid‐phase assay described here, serially diluted antiserum is incubated in microtiter wells previously coated with the relevant antigen.

Regulation of the Juvenile Hormone Titer
Annual Review of Entomology, 1981Juvenile hormone (JH) is produced by the corpora allata (CA) of insects. It regulates development and reproduction and also plays a crucial role in polymorphism. These functions have been amply reviewed (13, 21, 23, 29, 30, 112, 141). However, little information is available on the mechanisms of these effects, mainly because of the difficulty in ...

Rubella antibody titer. The significance of low-titered rubella antibodies.
Obstetrics and gynecology, 1978The hemagglutination inhibition (HAI) test is not mathematically precise and reproducible. Thus, it is critical to know whether or not the threshold titer (1 : 10) of detectable rubella antibody is indicative of true immunity. Three patients with a 1 : 10 HAI titer presented with subsequent rubella during gestation.

Estimation of hemagglutination-inhibition titers
Archives of Virology, 1975In the hemagglutination-inhibition test, simple relationships exist between units of hemagglutinating virus and hemagglutination-inhibition antibody titers. Equations have worked out which allow estimating antibody titers for different virus doses, provided all other parameters are kept constant.
