ELISA or immunoblot. In ANA detection IFA and immunoassays complement each other: one test is used for screening, the other for confirmation of positive or ambiguous test results.For further differential diagnosis single ANA subspecies may be analysed individually by enzyme-linked immunosorbant assay ...
The objective is to replace ANA-IFA by ANA-EIA as a screening test. Comparison studies between ANA-IFA and ANA-EIA have been performed with discordant results [8], [9]. Recently, some studies that evaluate COBAS Core HEp-2 ANA-EIA have been published [10], [11], [12], with ...
The indirect fluorescent antibody (IFA) test is sensitive, screens for a wide variety of known and unknown autoantibodies, and through pattern recognition offers insights into the probable identity of the antigen and associated autoimmune disorder. The AESKU.BION ANA (Anti-Nuclear Antibody) Test Syste...
The assessment of antinuclear antibodies (ANA) by indirect immunofluorescence (IFA) allows detection of >50 characteristic autoantibodies, making it a highly sensitive method and screening test. The semiquantitative method is based on the identification of patterns at different dilutions, and each ...

and an IFA test was performed for 375 patients. Of these, 18 patients had positive results in PCR tests targeting two or more genes forA. phagocytophilum. An IFA test for anaplasmosis was performed in 154 of the patients, and 15 patients showed a four-fold increase in antibody titer betwee...
IFA test, fluorescence in situ hybridization, PCR) were used. Since these methods allow only certain enteropathogens to be detected, other species of protozoan parasites, potentially accumulated by the mussels, could be overlooked. Therefore, the present study employed four different dyes allowing the...
As reviewed by Von Mühlen et al. the ICAP experts did not yet reach consensus on the terminology to be used [18]. At the subsequent six ICAP workshops the classification system was elaborated upon by defining a few new patterns (HEp-2 IFA negative [AC-0], HEp-2 IFA undefined [AC-...
antibody titers have persisted as long as 3 years.22In the United States, a silicon disc-based ELISA assay is available commercially for detection of antibodies toA. phagocytophilum(Accuplex 4, Antech Diagnostics, Irvine, CA). The performance of this assay when compared with IFA...
