This report mentions various factors that are causative of fast-paced expansion of the
Immunoassays in R&Dmarket.
A / IN ADULTS TREATED with opioids for chronic pain, point-of-care (POC) urine drug screens (
immunoassays) for detecting opioids show a false-negative rate of 1.9%, a sensitivity of 92%, and a specificity of 93% compared with the gold-standard liquid chromatography tandem mass spectrometry (LC-MS).
(5) Healthy study participants who consumed 15 mg to 30 mg of biotin daily were shown to have biotin concentrations of over 30 ng/mL; these levels could interfere with biotin-based
immunoassays. (6)
The stepwise miRNA assay protocol is much slower than routine simultaneous incubation sandwich
immunoassays (e.g., sandwich
immunoassays performed on the Advia Centaur[R] analyzer used in this work only require 7.5-min incubations).
B, Comparison of 125 PSA serum measurements made with Roche cobas
immunoassay (Roche Diagnostics, Indianapolis, Indiana) versus the MS PSA assay.
The other, published April 20 in Analytical Chemistry, demonstrates the effect in
immunoassays. In addition to Chou, the authors include post-doctoral researchers Weihua Zhang, Liangcheng Zhou and Jonathan Hu and graduate students Fei Ding, Wei Ding, Wen-Di Li and Yuxuan Wang.
Protein microarray glass slides utilizing the PATH technology are also available from leading life science consumable suppliers to enable researchers to perform ultra sensitive assays including sandwich
immunoassays, capture
immunoassays, protein profiling, and protein characterization.
Because pregnancy increases levels of thyroid binding proteins, a free [T.sub.4]
immunoassay to confirm an abnormal TSH level in pregnancy "is not as reliable because of these biological changes," he said.
Free [T.sub.4]
immunoassays aren't reliable in subgroups of patients with disturbances in binding proteins, Dr.
Each was detected in a bacteria-specific lateral flow
immunoassay strip to evaluate the ability of SEL to facilitate the detection of several foodborne pathogens simultaneously.
The authors indicated that technologic advances have improved the specificity of detecting SV40 antibodies and used an enzyme
immunoassay based on viruslike particles (VLPs) to perform the analysis (1).
today announced their conclusion of a joint research agreement for development of a new KL-6 test kit consisting of an in-vitro, supplementary diagnostic marker for interstitial pneumonia compatible with LUMIPULSE (automatic chemiluminescent enzyme
immunoassay) systems.
