Calloway’s Pain Care and Workers Comp protocols include a unique split chamber prescreening cup for preliminary results in less than five minutes. Although this prescreening tool needs to be confirmed by a laboratory test before taking definitive action, the Calloway Cup is excellent for early identification of possible problems with patients undergoing pain management treatment.

Most instant-result devices on the market have the problem that their drug detection chemicals can leech into the specimen and contaminate the entire sample - making it undependable for subsequent testing by a laboratory (including Calloway’s GC/MS and LC/MS-MS). Calloway's Cup isolates the portion of the urine specimen used for the pre-screen, eliminating this contamination while readying the sample for express shipment.

Calloway’s Cup also has a unique snap top to safely seal the specimen for collection and shipping without leaking or contamination.
