# Calculation formula

Life Sciences Quality Control & Assurance enables the definition of a calculation formula for test group lines (that is, a mathematical formula used to [calculate the test results](/life-sciences/docs/calculated-results) based on operations and other test outcomes). The **Calculation formula** field is available in the **Test** tab of the test group lines. A default formula is assigned and inherited from the selected **Test method**.

For tests that have a **Calculation formula** defined, it is possible to click the **Check formula** button. The **Check formula** form allows the simulation of the formula calculation using the test **Standard** values and checks for syntax errors (for example, incomplete formulas like “@Potency@/10*”.).

#### Example

A test group is available with the following tests:

- Test “Potency”. The **Standard** value in the specifications is “250”.
- Test “Potency%” with **Calculation formula** set as “@Potency@/10*4”.

The user can open the **Check formula** form for test “Potency%” and click the **Validate** button. The system returns “100” as a result (calculated using “250” from the “Potency” test).
