Overall, the CBC is not diagnostic for MS but can help rule out other conditions.

What will show up on Breathalyzer a besides alcohol?

The short answer is many things. Some types of inhalers can show up for 30 to 60 minutes; strong mouthwash sometimes for 10 minutes; and to a lesser degree dental adhesives and cleaners, and some industrial solvents. In some cases diabetics can even mess with results slightly.

The longer answer: Most of these only show errors with exceptionally abnormal levels of the interfering substance, the tests have come a long ways and modern technology isn't easily fooled. And people who use the devices are aware of the limitations and how to adjust to them. For example, in the case of an inhaler they would simply wait or do any of a dozen other methods for testing levels. None of these would even slightly cause error in a blood test for example.

Twenty or thirty years ago the tests were a bit more supportable to errors due to odd situations (or intentional tampering).
