IDS-iSYS Insulin-like Growth Factor-I (IGF-I)
Disease Areas: Growth Factors
Format: CLIA
Description
A fully automated assay for the measurement of IGF-I in human serum or plasma on the IDS-iSYS system. The assay is intended for in vitro diagnostic use in the diagnosis and management of growth-hormone related disorders.
Features
- Exceptional lot to lot consistency – guarantees consistent and reproducible results required for long term therapy monitoring.
- Calibrated to new WHO IS (02/254) – conforms to the call for improved standardisation of IGF-I measurements from the Growth Hormone Research Society and the International IGF Research Society.
- Extensive global reference range – age and gender specific values provided in over 9000 samples.
- Low sample volume – suitable for paediatric samples.
- Excellent assay precision and accuracy – automated sample pre-treatment and IGF-II displacement method eliminates interference of binding proteins.
Physiology
- The IDS-iSYS IGF-I assay represents a new generation of assay which is calibrated to the 1st WHO International Standard for Insulin-like Growth Factor-I, NIBSC code: 02/254. An extensive normative data study has been completed of over 9000 samples. The assay also conforms to the 2011 Consensus Statement on GH and IGF-I assays1.
