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
Similar to EIA, the second-tier immunoblot is a serologic test
that detects antibodies produced against B.
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.
1] Serologic tests
require venipuncture, followed by a delay as the serum is either sent to a reference laboratory or the sample is prepared for an in-office test.
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.
Eighty-five patients were excluded because: the wrong serologic test
had been requested (one patient); the patient had refused screening (three patients); the patient's blood specimen was not received in the laboratory (six patients); the patient was treated with spectinomycin (three patients); or no blood was drawn for serologic screening owing to an oversight (72 patients).
Under the enhanced definition, however, 16 patients who had negative DFM results were considered to have syphilis, and Tp-PCR provided higher specificity and positive predictive value when compared with this definition than when compared to either DFM or serologic test
results alone (Table 1).
