What is the appropriate code for a soldier who was not present for the urinalysis?

When a soldier is not present for a urinalysis, the appropriate code to apply is Inspection Other (IO). This code is designated specifically for cases where a soldier is unavailable during a scheduled urinalysis or inspection, which might occur due to various valid reasons such as being on leave, in a medical treatment facility, or other circumstances that prevent their participation.

The use of the IO code helps maintain accurate records regarding the soldier's compliance with drug testing procedures without implying wrongdoing or misconduct. It ensures that the absence is properly documented and classified, allowing for appropriate administrative follow-up if necessary.

In contrast, the other codes pertain to different contexts. Probable Cause (PO) refers to situations where there is reasonable suspicion of drug use, requiring a urinalysis outside of the normal testing schedule. Mishap or Safety Inspection (AO) pertains to tests conducted due to incidents or accidents, and Rehabilitation (RO) is used when a soldier is undergoing treatment for substance abuse. Each of these codes serves specific situations and does not apply to cases of absence from the urinalysis.
