New attributes that are added to the SNOMED CT concept model (or to a SNOMED CT extension) may require their value to be concrete. Concrete values include integers (e.g. 500), decimals (e.g. 2.75) and , strings (e.g. "PANADOL"), and booleans (e.g. TRUE

.

The expression shown below uses both concept values and concrete values to represent a capsule that contains 500 mg of amoxicillin

. In represent a product containing precisely 500 milligram amoxicillin per oral tablet. In this case, the dose form, the active ingredient, the basis of strength substance, and the strength unit all use a concept as their value, while the strength magnitude is numerator and denominator are represented using a numeric value. The numeric value is Furthermore, the |Count of base of active ingredient| also uses a numeric value, and represents the number of substances that is the part of the ingredient that the strength of a given product is based upon. The numeric values are indicated in the expression by the preceding '#' symbol (e.g. #500).
