Defective antigen tubes generate false-positive QuantiFERON tuberculosis test results.
TO THE EDITOR—In recent years a significant shift in testing has occurred for diagnosing latent tuberculosis (LTB). The adoption of interferon gamma release assays (IGRA) has largely supplanted tuberculin skin test (TST) for both patient testing and employee screening. IGRA have advantages over TST in that they are unaffected by prior vaccination with bacillus Calmette–Guérin (BCG) vaccine and ...
متن کاملHelicobacter Pylori Diagnosis by Stool Antigen ELISA and Rapid Test
An evaluation of a rapid test for the presence of Helicobacter pylori from stool specimens looking for antigen proceeded for a period of 8 months from March to November 2011. A total of 212 stool samples were collected from 2 different hospitals in Holy Makkah City. Twenty six patients were positive for H. pylori by the ELISA test which was used as the gold standard. The rapid test when compare...
متن کاملDetermination of Helicobacter pylori Antigen in Stool Samples and Comparison with Rapid Urease Test in Patients Suspected of Helicobacter Infection
Background and Aims: Helicobacter pylori (H. Pylori) is the microorganism that infects nearly half of word's population. There are several invasive and non-invasive methods for diagnosis of infection. The main objective of this study was to evaluate antigen of H. Pylori in feces with H. pylori stool antigen (HpSA) test and comparison with rapid urease test (RUT) in the patients suspected to be ...
متن کاملNew cause for false-positive results with the Pastorex Aspergillus antigen latex agglutination test.
The Pastorex Aspergillus antigen test for detection of Aspergillus galactomannan antigen in the sera of patients with invasive aspergillosis is used in many clinical laboratories. A serum sample contaminated with Penicillium chrysogenum gave a strongly positive reaction (1:128) which was heat stable, was not eliminated by pronase treatment, and was not detected by a normal rabbit globulin contr...
متن کاملNew cause for false-positive results with the cryptococcal antigen test by latex agglutination.
The highly specific and sensitive latex agglutination test for cryptococcal antigen detection in cerebrospinal fluid is routine in many hospitals. Contamination of cerebrospinal fluid by a minute amount of syneresis fluid (surface condensation) from agar gave a strongly positive reaction which was heat stable, was not eliminated by pronase treatment, and was not detected by the normal rabbit gl...
