Common questions about manuals, registration, and support for this brand.
For the Express Results Integrated Multi-Drug Screen Cup, a negative result is typically indicated by the presence of a colored line in the test region (T). The absence of a line next to a specific drug name suggests a preliminary positive result. Always refer to the specific package insert for cut-off concentrations and reading times, as results must be interpreted within a specific window (usually 5-10 minutes).
The CIC app is a digital tool integrated with Electronic Health Records (EHR) systems like eClinicalWorks. It provides healthcare providers with a time-sequenced view of a patient's diagnostic history to support clinical decision-making.
For technical issues regarding the CIC app or other Quest digital connectivity solutions, you can contact the Quest Technical Help Desk at 1-800-697-9302.
Tests billed with specified CPT codes may require a Z-Code Identifier to provide clarity to payers. These codes are managed via the Palmetto GBA DEX Diagnostics Exchange and help identify the specific molecular diagnostic test performed.
