Quality Standards and Financial Traceability

Achieving National Accreditation Board for Testing and Calibration Laboratories (NABL / ISO 15189) and NABH accreditation demands complete traceability across pre-analytical, analytical, and post-analytical workflows. Auditors scrutinize how specimen barcodes correlate with billing records, consent forms, and final diagnostic sign-offs.

Audit Trail Requirements

  • Timestamped logs of who created, edited, and approved billing invoices.
  • Verification that test pricing matches authorized tariff lists without unauthorized manual overrides.
  • Immutable records linking each billed test line item to the performing lab technician and reporting pathologist.

By leveraging Relaso Lab Routing & Invoicing, laboratories maintain tamper-proof audit trails that satisfy accreditation inspectors effortlessly.
