Cross reactivity of dihydrodigoxin with a commercial digoxin kit.
1086 CLINICAL CHEMISTRY, Vol. 24, No. 6, 1978 ally, the normal introduction time of 2 s leads to the good precision and recovery as found with the use of larger sample volumes, as discussed in the original letter. Corning has completed a rewording of their instruction manual to clarify the statement “slowly inject the sample until the ‘Sample in Place’ indicator lights,” so that it is obvious t...
متن کاملSome factors affecting a commercial kit for radioimmunoassay of digoxin using tritiated digoxin.
Some factors affecting results of digoxin determinations using one commercially available radioimmunoassay kit are described and discussed. Serum of pregnant women, cord blood, amniotic fluid and serum of patients taking spironolactone may show erroneously high digoxin activity due to lack of specificity of the antiserum. Cross-reaction with digitoxin was found to vary substantially with antibo...
متن کاملComparison of Thyroglobulin Measurements Using Three Different Immunoassay Kits: A BRAMHS Tg-Plus RIA Kit, a BRAMHS hTg Sensitive Kryptor Kit, and a Beckman Coulter ACCESS Immunoassay Kit
BACKGROUND Second-generation thyroglobulin immunometric assays (Tg-IMAs) have been developed with improved sensitivity. Our aim was to compare the diagnostic value of Tg-IMA measurements using a Kryptor (BRAHMS AG) kit (Tg-K) and an ACCESS (Beckman Coulter) kit (Tg-A) with that of the first-generation Tg measurement using a Tg-plus (BRAHMS AG) kit (Tg+). METHODS We enrolled 82 differentiated ...
متن کاملIntercomparison of seven radioimmunoassay kits and a fluorescence polarization immunoassay kit for digoxin.
Samples from 33 patients being treated with digoxin and three concentrations of control material were analyzed for this drug by use of seven radioimmunoassay (RIA) kits and an automated fluorescence polarization immunoassay (FPIA) system. CVs ranged from 2.4 to 6.4% for the FPIA system and from 4.6 to 7.4% for two RIA methods. In the analysis of between-method variability of RIA kits, CVs range...
متن کاملModification of a commercially available digoxin radioimmunoassay kit for higher precision.
The procedure prescribed for the Schwarz/Mann 125-l-digoxin kit was modified with regard to pipetting and counting procedure. Incubation time with dextran-coated charcoal was also investigated. The modifications resulted in a significantly higher precision wihout introduction of a systematic error and the analysis time per eight-tube batch was decreased by 20 min.
