The normal ANA level is typically defined as a titer of 1:40 or lower, although specific reference ranges and cutoffs can vary among laboratories. A titer of 1:40 means that antibodies can be detected when the blood is diluted 40 times. Levels above this threshold are generally considered ...
A method for diagnostics of anaplasmosis infection by means of detection of the level (titer) of antianaplasmosis antibodies in reaction of indirect immunofluorescence (RIIF). The particulate antigen of the strain Anaplasma marginale BB1 is used as diagnostic preparation of anaplasmosis antibody ...
far, the quantity in absolute terms and in comparison to the host hemolymph volume is very small. Consequently, parasites would have to produce very large amounts of hormones in order to substantially alter the titer in the host. The possibility of release of hormone metabolites seems more ...
A correlation between titer, amount of lines on the Western-blotts and efficiency of ANA-specificity assessment was observed, what means, that in "high-titer" sera (possessing usually more lines on the blotts) the efficacy of ANA (+) specificity assessment was higher, but not more than in ...
