If they test for amphetamines, phentermine could come up as a positive.

 

A false positive.

 

If they confirm the test for GCMS (a special confirmatory test), it will show that phentermine is the positive and not amphetamine

 

Blood alcohol will not show phentermine.

 

If you have follow up questions, please ask prior to accepting.

How long will Phentermine stay in system and show up on blood test?

Hello
This is not exactly an amphetamine but can show up as an amphetamine
This can be usually 2 to 5 days, even a little longer depending on use.
Phentermine has a somewhat longer half life so 5 days is more the norm rather than 2.

In fact is also depends on the type of screen being used..in some the drug will not cross react well as amphetamine [which it is not , it is a related compound] and some will...the "polyspecific" test will tend to show it well.

5 days would be a good estimate of how long it would show in urine.

If it shows up positive it will then be sent to confirmatory testing which will identify the exact drug.

Let me know if you have further questions, details or need clarification, just use reply.......
