Insulin-like Growth Factor-1 (IGF-1) With Z Score
Also known as: IGF-1
Use
The IDS-iSYS Insulin-like Growth Factor-I (IGF-I) assay is an in vitro diagnostic device intended for the quantitative determination of IGF-I in human serum or plasma on the IDS system. Results are to be used in conjunction with other clinical and laboratory data to assist the clinician in the assessment of growth disorders.
Special Instructions
Age and gender must be supplied for Z score to be calculated. This test may exhibit interference when a sample is collected from a person consuming a high dose of biotin. Patients should stop biotin consumption at least 72 hours prior to collection.
Limitations
Considerable differences exist between the currently available assays regarding the results of IGF-1 measurements. Patients consuming high doses of biotin might exhibit interference in this test.
