Does adderall show up in blood tests?
The amphetamine concentration in blood can be analyzed to tell whether they are within therapeutic limits as well, meaning if you have a prescription, it can be determined if you take more then what is prescribed. The dextro and levo isomers can also be disinguished from one another, meaning that if you are prescribed Adderall and only test positive for Dextroamphetamine (I.E. if you took Vyvanse or Dexedrine instead), that would alsoshow up.
