A considerable demand for convenient, rapid, inexpensive assays of ferritin in serum has been generated in recent years in hospital laboratories and blood banks. We describe a simple and rapid particle-enhanced turbidimetric immunoassay suitable for routine application in a Monarch 2000 centrifugal analyzer with commercially available reagents. This fully automated assay (y) requires no pretrea...

To select optimal cut-off values of tumor markers in cerebrospinal fluid for the diagnosis of meningeal carcinomatosis, the concentrations of CEA, CA125, CA153, CA199, CA724, CYFRA21-1, AFP and NSE were determined by means of double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) in 21 MC patients, 25 cancer patients without leptomeningeal disease (group one) and 45 meningitis patie...

OBJECTIVE We measured serum NT-proBNP levels in 2 groups of young patients (0-36 months) with congestive heart failure (CHF) secondary to congenital heart malformations (CHM). METHODS The first group included 23 patients prior to surgery for heart malformations. The second group included 12 patients with CHM within 24 hours post-operation. NT-proBNP levels were measured by an enzyme-linked im...

apolipoproteins, and obesity in children. Japanese school boys (36obese and lelnonobese) and girls (24 obese 111nonobese} aged from 10 to 14years were examined. Serum MDA-LDL Ievels were measured bv the double-antibody sandwich ELISA method. Serum LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglycerid (TC), apolipoprotein Al (Apo Al), apolipoprotein B (Apo B), and apolipoprutein E (Apo E...

In liver disorder, prothrombin time (PT) is elevated, and fibrinogen level decreased which are considered predictors of increased bleeding risk. We aimed at determining whether increased PT and fibrinogen value reflect the haemostatic potential and bleeding risk in patients with liver disorder. The study comprises a total of 135 subjects including patients with liver disorder (n=75) and healthy...

The automation offered by modern program proof tools goes hand in with the capability to interact tool when verification fails. SPARK tries help user providing right information, so that can complete proof. In this article, we present these mechanisms and how they work concretely on a simple running example.

BACKGROUND Small molecules classified as haptens are generally measured by competitive immunoassay, which is theoretically inferior to noncompetitive sandwich immunoassay in terms of sensitivity and specificity. We created a method for developing sandwich immunoassays to measure haptens on the basis of antimetatype antibodies. METHODS We generated antimetatype monoclonal antibodies against a ...

INTRODUCTION The objective of the present study was to compare QUANTA Flash dsDNA, a chemiluminescent immunoassay (CIA) on the BIO-FLASH, a rapid-response chemiluminescent analyzer, to three other anti-dsDNA antibody assays and to Crithidia luciliae indirect immunofluorescence test (CLIFT). METHODS In the first part of the study, 161 samples, 61 from patients suffering from systemic lupus ery...
