Results for all other serologic tests
were negative, leading to a modification of the diagnosis to confirmed CSG viral encephalitis.
Of the patients, 610 (25%) had abnormal serologic tests
, and 240 (39%) underwent endoscopy with biopsy.
According to the wide variation in the prevalence of celiac disease exists between different setting with different characteristics of patients and various serological tests, now it is the time to decide about considering celiac serologic tests
in suspected IBS patients, keeping in mind these controversies.
Both the AGA and the North American Pediatric Society for Pediatric Gastroenterology state that tissue transglutaminase and endomysial antibodies are the most useful serologic tests
. Antigliadin antibody tests are considered inferior in terms of diagnostic accuracy.
results might be used by public health officials to determine whether a given illness meets the surveillance case definition, but the methods themselves were not developed for this purpose.
Patients with suspected anaplasmosis or ehrlichiosis should be treated promptly with doxycycline, without regard to initial serologic test
results, because antibodies in the first week of illness frequently are not detected.
But serologic tests
conducted on large, random populations such as blood donors have shown that celiac disease affects about 0.5% to 1% of the U.S.
The laboratory criteria consistent with a diagnosis of LGV include a positive result (i.e., titer [greater than or equal to]1:64) on a complement fixation test for chlamydiae or a high titer (i.e., typically >1:128, but can vary by laboratory) on a microimmunofluorescence serologic test
Furthermore, we were cautious with our interpretation of the serologic test
results and, therefore, claimed only 2 confirmed cases (4), 1 on the basis of egg detection and the other on positive serologic test
results by using 2 different methods.
Among the many serologic tests
available, the RPR test and FTA-ABS test are the most widely employed.
The HCW with positive serologic test
results was a radiology technician who assisted in the procedure.
Conference recommendations were grouped into four categories: 1) serologic test
performance and interpretation, 2) quality-assurance practices, 3) new test evaluation and clearance, and 4) communication of developments in Lyme disease (LD) testing.
