  • enzyme immunoassays
  • To systematically study the influence of temperature deviations on assay parameters like signal variation coefficients, limit of detection and measurement range, direct competitive enzyme immunoassays for the determination of two anthropogenic markers, caffeine and carbamazepine, were run at different temperatures above and below room temperature during individual assay steps. (kobv.de)
  • concentration
  • The potential exists that high fosphenytoin concentrations in plasma after IV and IM administration (rarely exceeding 200 and 40 mg/L, respectively) might lead to aberrantly high phenytoin concentration determinations when immunoassays are used. (thefreelibrary.com)
  • methods
  • When the competitive HSA immunoassay was validated against an independent test both methods gave almost the same results. (uni-regensburg.de)
  • Methods, articles, and kits for obtaining elevated concentrations of a substance from a sample that has become bound, for example by providing a positive test result in an immunoassay or other binding assay. (google.com)
  • invention
  • This fluorescence polarization invention can be practiced on a variety of fluorescence instruments, including prior-art equipment such as microscopes and multi-well plate readers. (google.com)
  • An apparatus and method according to the invention combine more than one optical modality (spectroscopic method), including but not limited to fluorescence, absorption, reflectance, polarization anisotropy, and phase modulation, to decouple morphological and biochemical changes associated with tissue.

  • An acetaminophen test system is a device intended to measure acetaminophen, an analgestic and fever reducing drug, in serum. (medicregister.com)
  • method
  • Linkage to proteins was achieved by the N-hydroxysuccinimide ester method, which was demonstrated for the systems HSA-anti-HSA and myoglobin-anti-myoglobin. (uni-regensburg.de)
  • complications
  • 1 AAS are known to affect the haemostatic system, 2, 3 and systemic emboli and thrombotic complications have been reported in several androgen using athletes. (bmj.com)
  • clinical
  • A high pressure liquid chromatography system for clinical use is a device intended to separate one or more drugs or compounds from a solution by processing the mixture of compounds (solutes) through a column packed with materials of uniform size (stationary phase) under the influence of a high pressure liquid (mobile phase).

  • A clinical toxicology control material is a device intended to provide an estimation of the precision of a device test system and to detect and monitor systematic deviations from accuracy resulting from reagent or instrument defects. (medicregister.com)
  • plasma
  • Thus, ECE-1a has two equally relevant activities in this recombinant system for CHO cells: (1) an intracellular, probably intravesicular activity, corresponding to the ECE-1a-mediated step of ET-1 biosynthesis and (2) an extracellular activity at the plasma membrane. (ahajournals.org)
  • Cross-reactivity of fosphenytoin in two human plasma phenytoin immunoassays. (thefreelibrary.com)
  • test
  • A cholinesterase test system is a device intended to measure cholinesterase (an enzyme that catalyzes the hydrolysis of acetylcholine to choline) in human specimens. (medicregister.com)
  • A breath-alcohol test system is a device intened to measure alcohol in the human breath. (medicregister.com)
  • A low cost optical system which incorporates a low ultraviolet output tungsten halogen light source and solid state photodetectors and circuitry in such a way as to provide reliable fluorometric test results. (google.com)
  • means
  • a mirror located between the sample region and the objective for directing light from the excitation means to the sample region, the mirror being small relative to the objective such that a substantial portion of the fluorescence emitted by the sample region towards the objective reaches the objective without impinging on the mirror.
