Abstract

A specific and sensitive radioimmunoassay for adrenomedullin has been developed. Half‐maximal inhibition of binding of radioiodinated adrenomedullin was observed at 4 tool/tube. The radioimmunoassay recognized the entire adrenomedullin molecule and has little crossreactivity with adrenomedullin fragment peptides. Adrenomedullin‐like immunoreactivity was found to circulate in human plasma at considerable concentration (3.3 ± 0.39 ). The immunoreactivity of adrenomedullin was eluted at almost the same position as synthetic adrenomedullin on gel‐filtration chromatography and reverse‐phase high‐performance liquid chromatography, suggesting that circulating adrenomedullin recognized by the present radioimmunoassay is identical or very similar to authentic adrenomedullin. Plasma immunoreactive adrenomedullin significantly increased in patients with hypertension, with a progressive rise proportionate to disease severity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
