Measuring antibodies to Bordetella pertussis antigens is mostly done by enzyme-linked immunosorbent assays (ELISAs). We compared the performance of five commercially available ELISA kits with the help of 65 serum specimens which were repetitively tested for evaluation of the kits. The specimens contained 20 paired serum samples from patients with clinical pertussis, 15 samples were from childre...

We evaluated six commercial radioassay kits in which tritium or iodine tracers are used to measure serum folate. We assessed the adequacy of the literature supplied with the kits, within-run precision, reagent stability, analytical recovery of added pteroylglutamic acid and N-methyltetrahydrofolic acid, results of analysis of patients' samples, and minimum detection limits. There were serious d...

In this study, food samples were intentionally contaminated with Escherichia coli O157:H7, and then DNA was isolated by using four commercial kits. The isolated DNA samples were compared by using real-time PCR detection of the Shiga toxin genes. The four kits tested worked similarly.

Optimal care for breast cancer patients undergoing aromatase inhibitor (AI) treatment is ensured when estradiol (E2) levels are adequately suppressed. To assess treatment efficacy accurately, it is important to measure the serum E2 levels using a well validated assay method with high sensitivity and specificity. This translates into the urgent need to evaluate various E2 immunoassay kits, which...

Rapid immunochromatography test (RICT) kits are commonly used for the diagnosis of canine parvovirus (CPV) because their rapid turnaround time, simplicity, and ease use. However, potential cross-reactivity low sensitivity can yield false-positive or false-negative results. There 4 genotypes CPV. Therefore, evaluating performance reliability RICT CPV detection is essential to ensure accurate app...

OBJECTIVES The evaluation of Mutans streptococci (MS) is one of the index for caries risk. Dentocult(TM) and CRT(TM) are commercial kits to detect and evaluate MS, conveniently. However, the evaluation of MS has also been carried out simply using an instruction manual. But the instruction manual is not easy to use for evaluation of MS. The aim of this study was to examine the utility of modifie...
