Possibly but this is extra testing and will cost ALLOT,
generally laboratory initial and rapid home tests use min cutoff level for detection (nano gams of drug/ drug metabolites /substance per milliliter urine) so if the concentration is above this cutoff you fail positive, under you pass. Now , laboratory standard requires each "False positive" samples from the screening test to be confirmed usually by GC/MS test (Gas Chromatography / Mass Spectrometry). GC/MS test have low cutoff level ,can tell the difference between chemically
similar drugs, or difference between drugs and medications, and can tell are you light, moderate or heavy user. For Ritalin (Methylphenidate) can be tested for in urine, though it is not part of the standard drug testing but have short detection time - 2-5 days .Also may show false positives for amphetamine/ methamphetamine in standard drug test (home tests , initial lab test).
