Determination of prostate-specific antigen in serum by immunoradiometric assay.
A better understanding is needed of the role of pre-analytical factors if prostate-specific antigen (PSA) is to be reliably used as a tumor marker. Reports on the analytical performance of TANDEM-R PSA (Hybritech, Inc., San Diego, CA) differ considerably with respect to detection limit and imprecision, differences that might be due (e.g.) to the use of different control matrices, to between-bat...
متن کاملHighly sensitive immunoradiometric assay for serum thyroglobulin with minimal interference from autoantibodies.
Five monoclonal antibodies (MAbs) directed against antigenic domains on thyroglobulin (Tg) not recognized by most anti-Tg human autoantibodies (aAbs) have been used to develop an improved IRMA for serum Tg with a limit of detection of 0.2 micrograms/L. Samples are incubated for 3 h in tubes coated with four anti-Tg MAbs. After washing, the tubes are incubated with the tracer MAb for 20 h at roo...
متن کاملA sensitive immunoradiometric assay for serum thyroid stimulating hormone.
The value as a thyroid function test of a new, rapid, and highly sensitive immunoradiometric assay for thyroid stimulating hormone (TSH) was assessed in 188 consecutive new patients with suspected hyperthyroidism. The diagnosis was made on clinical grounds and on the basis of serum total triiodothyronine and thyroxine concentrations and the response of TSH to thyrotrophin releasing hormone (TRH...
متن کاملDetermination of intact parathyrin by immunoradiometric assay evaluated in normal children and in patients with various disorders of calcium metabolism.
We report the reference values for intact parathyrin (PTH) measured by a two-site immunoradiometric assay (IRMA) during childhood. The study has been carried out in 215 healthy children and adolescents, ages 2.0 to 18.7 years. Some patients with altered mineral homeostasis were also studied to assess the sensitivity of the method in a clinical setting. Mean intact PTH concentrations were 30.8 (...
متن کاملElectrochemical Behavior and Highly Sensitive Voltammetric Determination of Doxepin in Pharmaceutical Preparations and Blood Serum Using Carbon Ionic Liquid Electrode
In this manuscript, the electrocatalytic oxidation of doxepin (DOX) was studied at a carbon ionic liquid electrode, fabricated using graphite, and the ionic liquid 1-octylpyridinium hexaflourophosphate (OPFP). The surface of the proposed electrode was characterized by scanning electron microscopy. Differential pulse voltammetry was applied as an analytical technique for quantification of sub-mi...
