Does Adderall show up on a drug test? Yes. Adderall is an amphetamine, and Vyvanse becomes one in the body, so both read on the AMP (amphetamine) panel of a urine drug test. Having a valid prescription does not change what the screen reads. Below: what the AMP line reports, why a specimen can still read presumptive positive on the on-site screen when the prescription is valid, and what a laboratory report adds.
This post is about how the test reads. It is not medical advice, and it does not recommend, time or rule out any medicine. Questions about a specific prescription belong with the prescriber.
Adderall and Vyvanse are both amphetamines
Adderall is a mix of amphetamine salts: its FDA labeling lists salts of dextroamphetamine and amphetamine. Vyvanse is one step removed. Its active ingredient, lisdexamfetamine, is described on its FDA label as a prodrug of dextroamphetamine: the body converts it into dextroamphetamine. Either way, the active drug is an amphetamine.
Amphetamines are stimulants that include some prescription ADHD medicines like Adderall and Dexedrine, as well as illicit forms. Most urine test cups print the class as AMP, and a Testr report prints it as AMP (Amphetamine), one of 14 drug panels. If other codes on a cup are unfamiliar, every drug test abbreviation is decoded here.
What the AMP panel reads
A certified collector reads the 14-panel rapid urine screen on site. A specimen reads presumptive positive on the AMP strip at or above the 500 ng/mL cutoff. The read gives no measured level, and the line says nothing about which product the amphetamine came from.
The panel's published window: usually detectable in urine for 2-4 days after use, at a 500 ng/mL screening cutoff. That range is typical rather than a guarantee. How much was taken, how often, body weight and hydration all move it. The panel page sets out how long amphetamines stay in urine next to the AMP cutoff.
A negative AMP line means the specimen did not read presumptive positive at the 500 ng/mL cutoff when it was collected. It is not proof that no amphetamine was ever taken.
With a valid prescription, a specimen can still read presumptive positive
The AMP panel's own note is direct: "A valid ADHD prescription can cause a positive." That is not an error by the strip. The strip responds to the amphetamine class, and amphetamine from Adderall or Vyvanse taken exactly as prescribed is still in that class.
The on-site read cannot tell a prescribed medicine from any other source. The person tested can tell the collector about a prescription at the visit, and the laboratory step below is where a valid prescription is accounted for.
An At-Home Rapid Test that is not upgraded stops there: the result is the on-site read alone, with no laboratory report behind it.
Where the prescription is accounted for: laboratory confirmation
Under the Rapid Test with Laboratory Confirmation, the specimen is sealed, travels with its chain of custody intact to a CAP-accredited laboratory, and is tested by LC-MS/MS, a method that identifies each compound and measures its level. Instead of one class line, the laboratory menu's amphetamines class lists two compounds, each with its own cutoff:
Amphetamine, 100 ng/mL
Methamphetamine, 100 ng/mL
Amphetamine from Adderall, Vyvanse, Dexedrine or an illicit source is measured as one compound, amphetamine, so the report names amphetamine, not the brand that supplied it. The laboratory measures amphetamine and methamphetamine separately, each against its own 100 ng/mL cutoff, so the report shows whether amphetamine, methamphetamine or both are at or above that cutoff, and at what level, in about 72 hours. The two sets of numbers are not comparable: 500 ng/mL applies to the AMP class read as one, and each laboratory cutoff applies to a single named compound. The full menu covers 81 substances in 31 drug classes.
Every laboratory report then goes to a Medical Review Officer (MRO), a physician who reviews laboratory-confirmed results and accounts for valid prescriptions before the report is released. That review is the step where a valid Adderall or Vyvanse prescription is taken into account.
If the visit was booked as the At-Home Rapid Test, the app allows an upgrade to laboratory confirmation for 2 hours after collection, a limit set by specimen viability. The 2-hour upgrade window walks through that timing.
AMP is not MET
Methamphetamine has a panel of its own, printed as MET or mAMP. It is most often illicit (crystal meth) but occasionally prescribed as Desoxyn. The MET screen uses the same 500 ng/mL cutoff, and its published window is worded the same way: usually detectable in urine for 2-4 days after use, at a 500 ng/mL screening cutoff. Its note adds that certain prescriptions and some cold-medicine ingredients can trigger a screen. See how long methamphetamine stays in urine.
Adderall's FDA labeling lists salts of amphetamine and dextroamphetamine, and methamphetamine is not among them. A specimen that carries methamphetamine often carries amphetamine too, so it can read presumptive positive on AMP as well as on MET, each at or above its 500 ng/mL cutoff. When the two need telling apart, the laboratory does it: it measures amphetamine and methamphetamine as separate compounds, each against its own 100 ng/mL cutoff, and the report shows whether amphetamine, methamphetamine or both are at or above that cutoff, and at what level.
What about Ritalin?
Ritalin is methylphenidate, a different stimulant. The laboratory menu files it as its own class, separate from amphetamines, and lists two compounds: methylphenidate and ritalinic acid, each at 10 ng/mL. None of the 14 panels on the rapid screen is a methylphenidate panel, and Testr does not claim the AMP panel reads it, so methylphenidate is reported only when laboratory confirmation is ordered.
The other panels have their own documented causes of a presumptive positive, set out in what can cause a false positive, panel by panel.
AMP on other tests
AMP is one of the five base panels that 5-panel and 10-panel tests share. A standard 5-panel test covers amphetamines, cocaine, THC, opiates and PCP, so a standard 5-panel cup has an AMP line too. What a 5-panel drug test screens for covers the rest of that list.
AMP is a label, not a standard. Another cup can print the same three letters with a different cutoff. A Testr visit screens all 14 panels every time.
Testing a teen, a client or an employee
One booking covers one person, and a parent, a professional or an employer can book on someone else's behalf, with that person's consent taken at booking. When the person tested is a minor, a parent or legal guardian must be present for the whole visit and signs the consent in the minor's place. See Testr for parents.
Therapists, psychologists and family-law professionals who order for clients can read Testr for professionals. For a court matter, ask your attorney or the court what they accept. Employers can book non-DOT testing only, and whether a workplace policy accepts a prescription is a question for employment counsel. DOT vs non-DOT drug testing explains the difference.
Getting a 14-panel screen in Los Angeles
Book in the Testr iOS app or at testrla.com/book and choose a 30-minute arrival window from 7 AM to 7 PM, seven days a week, at an address within 20 miles of Century City. The booking screen checks the exact address against the live service area. The earliest window can start in as little as 3 hours from booking.
The collector arrives in plain clothes and an unmarked vehicle and confirms identity with the 4-digit PIN shown in the booker's app. The specimen's temperature is checked, and a tamper-evident seal is applied and photographed. Every order carries a chain-of-custody code. Testr tests urine only.
Only the account holder receives the result, in the app or as a PDF at testrla.com/account, unless they give written consent for it to go to a named third party. The difference between negative, presumptive positive and laboratory-confirmed is laid out in how to read a Testr drug test result.
Questions people ask
Does Adderall show up on a drug test?
Yes. Adderall is a mix of amphetamine salts, so it reads on the AMP panel. On a Testr screen, a specimen reads presumptive positive on AMP at or above the 500 ng/mL cutoff.
Does Vyvanse show up on a drug test?
Yes. The FDA label describes lisdexamfetamine, the active ingredient in Vyvanse, as a prodrug of dextroamphetamine, an amphetamine, so it reads on the same AMP panel as Adderall, where a specimen reads presumptive positive at or above the 500 ng/mL cutoff.
How long does Adderall stay in urine?
Adderall reads on the AMP panel. The panel's published window: usually detectable in urine for 2-4 days after use, at a 500 ng/mL screening cutoff. That range is typical rather than a guarantee, and how much was taken, how often, body weight and hydration all move it.
Does a prescription change what the screen reads?
No. The on-site screen reads the amphetamine class against its 500 ng/mL cutoff, whatever the source, so a specimen from someone taking a valid prescription can still read presumptive positive at or above that cutoff. The person tested can tell the collector about a prescription at the visit. When laboratory confirmation is added, the laboratory report goes to a Medical Review Officer (MRO), a physician who reviews laboratory-confirmed results and accounts for valid prescriptions before the report is released.
Will Adderall show up as meth?
Adderall is not a source of methamphetamine. Its FDA labeling lists amphetamine salts, not methamphetamine, and the metabolism it describes does not produce methamphetamine. Laboratory confirmation reports amphetamine and methamphetamine separately, each against its own 100 ng/mL cutoff, so the report shows whether amphetamine, methamphetamine or both are at or above that cutoff. On the rapid screen, methamphetamine has its own panel, MET, separate from AMP.
Does Ritalin show up on a drug test?
Ritalin contains methylphenidate, and the 14-panel screen has no methylphenidate panel. Testr does not claim the AMP panel reads it. The laboratory menu lists methylphenidate and its breakdown product, ritalinic acid, at 10 ng/mL each, so they are reported only when laboratory confirmation is ordered.
A certified collector can come to a home or workplace address within 20 miles of Century City in as little as 3 hours, 7 AM to 7 PM, seven days a week, and the booking screen checks the exact address. Book a visit when you are ready.
