| description | Mean cerebellar diameter for gestational age predicted from a regression formula derived from a standard population. | |
| status | ACTIVE | |
Fully-Specified Name | ||
| component | Diameter.transverse.mean | |
| property | Len = Length | |
| 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 | |
| method | Estimated from gestational age | |
