| description | IGF-1 is used by physicians as a screening test for growth hormone deficiency and excess in acromegaly and gigantism. Interpretation of IGF-1 levels is complicated by the wide normal ranges, and variations by age, sex, and pubertal stage. Clinically significant conditions and changes may be masked by the wide normal ranges. For this reason, it is useful to report by Z score, a statistical measure that is useful for comparing data points derived from populations with different means and/or standard deviations. | ||

| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser/Plas Ser = Serum Plas = Plasma | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
