| Authority | hl7 |
| Description | Models a ratio of values, i.e. where the numerator and denominator are both pure numbers. The `_valid_proportion_kind_` property of the `PROPORTION_KIND` class is used to control the type attribute to be one of a defined set. Used for recording titers (e.g. 1:128), concentration ratios, e.g. Na:K (unitary denominator), albumin:creatinine ratio, and percentages, e.g. red cell distirbution width (RDW). Misuse: Should not be used to represent things like blood pressure which are often written using a '/' character, giving the misleading impression that the item is a ratio, when in fact it is a structured value. Similarly, visual acuity, often written as (e.g.) "6/24" in clinical notes is not a ratio but an ordinal (which includes non-numeric symbols like CF = count fingers etc). Should not be used for formulations. |

"definition": "Models a ratio of values, i.e. where the numerator and denominator are both pure numbers. The `_valid_proportion_kind_` property of the `PROPORTION_KIND` class is used to control the type attribute to be one of a defined set.\n\nUsed for recording titers (e.g. 1:128), concentration ratios, e.g. Na:K (unitary denominator), albumin:creatinine ratio, and percentages, e.g. red cell distirbution width (RDW). \n \nMisuse: Should not be used to represent things like blood pressure which are often written using a '/' character, giving the misleading impression that the item is a ratio, when in fact it is a structured value. Similarly, visual acuity, often written as (e.g.) \"6/24\" in clinical notes is not a ratio but an ordinal (which includes non-numeric symbols like CF = count fingers etc). Should not be used for formulations.",
