Will s 4 diet pills show on my blood work results?

Hi Guest.  If I knew exactly what s 4 diet pills was, I could answer your question better.  I would not think the pills themselves would show up on blood work but it depends on if your pills are prescribed by a doctor or just over the counter.  Most all diet pills are stimulants derived from caffeine more commonly.  Are you having a drug test done or is it a blood test that checks your blood panel (sodium and potassium levels, etc.)  If you can explain what diet pill this is, I can do some research on it and see exactly what its ingredients are and can tell you if it will show up in some way.
