| description | The Simplified Disease Activity Index (SDAI) is a useful clinical composite score for measuring a patient's rheumatoid arthritis activity in a clinical setting. It is scored by simply adding the numerical values within each of a set of predetermined areas: a twenty eight joint assessment is used to measure tender and swollen joint count; a patient and physician global assessment of disease activity is measured using a visual analogue scale, and finally, levels of the protein C-reactive are measured (mgudl, normal <1 mgudl). | ||

| 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. | ||

| 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 | ||
