Brief Answer:
There's accuracy and then there's accuracy

Detailed Answer:
Ok... first... let us deal with it's ACCURACY. It detects stress hormones. Any nasal decongestant, asthma drug, quite possibly herbal energy thing will light up a urine test because they contain things that are similar to amphetamine.
methalphenadate is an amphetamine

Frankly, I would be more worried about a patient who is prescribed it and whose urine does NOT have it detectable (sign she is selling it!)

Hair tests 1) more accurate and 2) are the only way you can get data that really ought to be accepted everywhere about what you were doing in the past (about 1/2 to 1 inch of hair = 1 month...so... if female with 6 inches of hair that's definitely 6 months back you can clear.

But frankly I am unclear on the question:
" blood test for methamphetamine " in someone taking presumably prescribed
methalphenadate is what the test is supposed to do... show you are taking an amphetamine. You are. They should know that. They have you in a program presumably knowing you are on methalphenadate, it shows up in the urine.. why are they surprised?
Um....clear your name by showing them your medical records and pointing at the amphetamine drug you told them about ?

There are also cases in which the drug test messes up. Common on the check dipstick method quite uncommon on the more expensive CSI type (which is always used on hair testing).
