A 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 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 کاملPreparation of prostate specific antigen standards for immunoradiometric assay
Background: Immunoradiometric assay is one of the most common and precise methods for determination of prostate specific antigen (PSA) in clinical laboratories. Usual use of human serum in routine assays has many disadvantages such as easy contamination and precipitation, instability and unavailability. Thus in order to avoid these problems the artificial matrix was used which acts sim...
متن کاملPurification and iodination of antibody for use in an immunoradiometric assay for serum ferritin.
Antibodies were purified by affinity chromatography and radioiodinated by a conjugation method for use inthe immunoradiometric assay for serum ferritin. These procedures are simpler and more reproducible than those described earlier, and the radiolabeled preparations were usable for at least 13 weeks.
متن کاملImproved immunoradiometric assay for plasma renin.
BACKGROUND Our renin IRMA overestimated renin in plasmas with high prorenin-to-renin ratios. We suspected that the overestimation of renin was caused less by cross-reactivity of the renin-specific antibody with prorenin than by a conformational change of prorenin into an enzymatically active form during the assay. METHODS Because the inactive form of prorenin converts slowly into an active fo...
