Detailed Answer:
Hi,
Usually, quick cups (rapid screening tests) are designed to help detect traces or presence of methadone only (qualitative screening). They have their own level of detecting (usually lower).
With regards to lab tests, they have the reference range as they quantify, i.e. show the exact level of methadone, determining if they fall until the normal range or not.
So, when you do a rapid test, they show the presence of methadone only without explaining if it could be derived from opiate using or other medicines.
Hope it replied to your inquiry!
