The assay uses a high affinity polyclonal antibody which reacts with an isomerized form of an 8 amino acid sequence of the C-telopeptides of type I collagen (EKAHD-\u03b2-GGR). Cross-reactivity to a nonisomerized synthetic peptide form of the 8 amino acid sequence is less than 0.2%. Values obtained in a group of premenopausal women (age, 33.3 \u00b1 3.11 years) were 69 \u00b1 24 ng\/ml (n = 22). In a group of early postmenopausal women (age, 51.8 \u00b1 1.88 years) values obtained were 125 \u00b1 43 ng\/ml (n = 46), which represents an increase of 81% (p &amp;lt; 0.001). Values found in untreated patients with Paget's disease were 234 \u00b1 95 ng\/ml (n = 15), and for primary hyperparathyroidism we found 335 \u00b1 82 ng\/ml (n = 10). Interveneous administration of a bisphosphonate (Pamidronate) to Paget's disease patients for 3 days was reflected in the S-ELISA by a decrease in the values of 55% when compared with values before treatment (n = 15). Following treatment with another bisphosphonate (Alendronate) for 6 months, values were decreased to 48 \u00b1 19 ng\/ml (n = 12), which corresponds to a 62% decrease. Clinical results presented in this context support that the assay is a sensitive and specific index of bone resorption. It may, therefore, prove useful in the follow up of treatment of patients with metabolic bone diseases and in the clinical investigation of osteoporosis.<\/jats:p>","DOI":"10.1359\/jbmr.1997.12.7.1028","type":"journal-article","created":{"date-parts":[[2006,4,26]],"date-time":"2006-04-26T22:03:09Z","timestamp":1146088989000},"page":"1028-1034","source":"Crossref","is-referenced-by-count":104,"title":["Measurement
