Is there a need for a property qualifier value for 'Index' results? If not, what is the property? This is a calculation from quantitations that turns them into a numeric dimensionless result value in relation to the integer ordinal value '1.0' with this number representing equality, range being any decimal fraction number. e.g. Antibody index, Free androgen index, Haemolysis index, Lipaemia index, Icterus index. This is not a percent but a decimal fraction less than or greater than 1.0 without UoM.
