When a test is labeled for Professional Use, it means:

• The test is designed to be used by trained personnel such as healthcare professionals, laboratory technicians, or authorized workplace testers.

• It often requires interpretation by someone with expertise, as results may be more complex or require confirmation.

• These tests usually meet stricter regulatory standards and offer higher accuracy and sensitivity than home-use kits.

• They may not be sold for direct consumer use or at-home testing due to the need for proper handling and interpretation.

• Professional Use tests are commonly used in clinical settings, medical labs, rehabilitation centers, or workplaces with formal drug testing programs.

In short, Professional Use indicates the test is intended for controlled environments with trained operators to ensure accurate and reliable results.
