Key facts

Internal control result

This term is used to report the result for a lab test's internal control, which is also known as a built-in or procedural control, along with the primary patient result. Internal controls are used to evaluate various aspects of the test procedure, such as whether enough specimen was added or whether the specimen migrated through the test strip. They are built in to each individual testing device (e.g., card or test strip) and provide a pass/fail result when that device is used. Internal controls are different from external controls in that external controls are not built in to the test itself but rather are included with the test kit or sold separately, usually come as both positive and negative, and are used in place of a patient specimen to run the test in order to monitor whether it is working properly.
