We have developed a new Superagglutination test for serodiagnosis of infectious diseases. It differs from conventional plate/slide agglutination tests (PAT/SAT) by three additional steps: prior staining of serum antibody by adding a dye and addition of diluted biotinylated antiglobulin and avidin in sequence after mixing the antigen with the test serum. The new steps circumvent the problems of ...
Lung cancer is the leading cause of cancer death due, in part, to lack of early diagnostic tools. Bronchoscopy represents a relatively noninvasive initial diagnostic test in smokers with suspect disease, but it has low sensitivity. We have reported a gene expression profile in cytologically normal large airway epithelium obtained via bronchoscopic brushings, which is a sensitive and specific bi...
OBJECTIVE To determine the usefulness of the Clinical Risk Index for Babies II (CRIB II) and weight to predict mortality in preterm infants < 32 weeks treated with exogenous surfactant. MATERIAL AND METHODS Design: cohort for diagnostic test. Preterm babies < 32 weeks who received exogenous surfactant in a third level of care were included. The cutoff for CRIB II was evaluated and considered ...
conclusion it was concluded that elisa-based anti h. pylori igg test in saliva could be used as an alternative diagnostic test in the absence of other invasive procedures. background helicobacter pylori is known as an agent which may involve in the occurrence of peptic ulcer, gastric cancer and also other known and unknown diseases. treatment of the infection with antibiotics eradicates the dis...
Abstract Background and Objectives: one of the endemic foci for Cutaneous Leishmaniasis in Iran is Mashhad in which limited outbreak have recently been reported. The commonly used method for diagnosis is the clinical features confirmed by direct microspic examination and culture or biopsy. We compared these two tests to determine the level of their sensitivity, specificity and positive predicti...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
Background: The most common methods for screening of patients with probable ischemic heart disease are stress test and in special conditions are perfusion scan, so that their positive results was important indication of coronary angiography. Although, predictive value of perfusion scan has been considered, with regard to the impact of technical and specialized factors and according to the sprea...

OBJECTIVE To determine the sensitivity and specificity of the rapid diagnostic test OptiMAL for diagnosis of Plasmodium vivax malaria. MATERIAL AND METHODS We included all the patients who sought medical attention in the San Martin Pangoa Hospital, Junin, an area endemic for vivax malaria in Peru, between October and December 1998, who had fever during the previous 72 hours and who were older...
We compared the performance of four rapid diagnostic tests (RDTs) for imported malaria, and particularly Plasmodium falciparum infection, using thick and thin blood smears as the gold standard. All the tests are designed to detect at least one protein specific to P. falciparum (Plasmodium histidine-rich protein 2 (PfHRP2) or Plasmodium LDH (PfLDH)) and one pan-Plasmodium protein (aldolase or Pl...
