Whether you work at a client organization submitting samples or a lab processing them, bLIS gives you the tools to track every step of the process. ## Key Capabilities Create and track batches of test orders linked to subjects and specimens. Order tests, enter results, and move them through validation and finalization. Monitor samples from collection through processing with full chain-of-custody tracking. Manage patient and donor records with demographics and identifiers. Generate and distribute finalized test result reports. How billing works, when charges are invoiced, and how pricing is determined. ## Who is this documentation for?
