Litigation-Ready Documentation from Day One.
When a drug test result is disputed, the credibility of the documentation determines the outcome. TestLedger™ replaces fragile paper trails with cryptographically sealed records that can be independently verified by auditors, attorneys, and regulators.
Employers face litigation, regulatory audits, and employee disputes. When a positive test is challenged, the question isn't just what the result was , it's whether you can prove the record was never touched after the fact. Paper and spreadsheets can't answer that question.
When a terminated employee challenges a positive drug test, employers must produce documentation proving unbroken chain of custody. Paper forms often contain unverified signatures, missing timestamps, or inconsistent collector notes that create openings for wrongful termination claims.
Spreadsheets and basic HRIS modules store test results, but offer no cryptographic evidence that data has not been modified after the fact. In an audit or deposition, there is no mechanism to prove a record was not backdated, edited, or selectively deleted.
Cannabis legalization across 24+ states has created a patchwork of employer obligations. Organizations operating in multiple jurisdictions need documentation that captures policy-specific test panels, thresholds, and consent workflows to remain compliant in every state.
Companies with distributed workforces rely on different collectors, clinics, and internal procedures across locations. Without a standardized digital workflow, documentation quality varies site to site, creating compliance gaps that surface during audits or legal discovery.
Many state drug-free workplace programs offer workers' compensation premium reductions for employers with compliant testing programs. Inadequate documentation can jeopardize these benefits, and incomplete records weaken post-accident claim defenses.
Medical Review Officers need clear, complete specimen documentation to process non-negative results efficiently. Missing collector information, unclear specimen IDs, or delayed paperwork extends the review cycle, creating liability windows and delayed hiring decisions.
Not lab errors. Not false positives. Procedural and documentation deficiencies give attorneys the leverage to challenge otherwise valid results, turning a $50 drug test into a six-figure legal exposure.
Turn every workplace drug testing event into a tamper-evident, independently verifiable record. TestLedger replaces fragile paper trails with structured records verified by auditors, attorneys, and regulators.
Authorized personnel record the test authorization, donor identification, consent, and collection details using a structured digital form. Standardized fields ensure consistent capture and establish the foundation of the evidentiary record.
Test results, MRO reviews, photographs, and supporting documents are attached before sealing. Each file receives an individual SHA-256 hash and is included in the evidence manifest, creating a complete, auditable evidentiary package.
The CryptoSeal™ engine generates a SHA-256 cryptographic fingerprint over the canonicalized evidentiary record, including all structured fields, chain-of-custody data, and attached evidence files. Each attachment is individually hashed and included in the evidence manifest. The record hash, operator identity, and timestamp are permanently sealed. Any modification to the record or associated evidence files results in a cryptographic hash mismatch, invalidating the seal.
Authorized parties, including attorneys, auditors, and regulators, can independently verify record integrity with the TestLedger Verification engine. The verification engine compares the current file hash against the original CryptoSeal™ SHA-256 fingerprint, confirming the record remains byte-for-byte identical to the version sealed at the moment of collection.
Customer records remain private and under the custody of the originating organization. TestLedger does not store or access the underlying files and operates solely as a cryptographic verification layer.
Two situations every drug testing program faces. The difference between a defensible record and an exposed one is whether the documentation was structured, timestamped, and cryptographically sealed at the time of the event.
Candidate's offer was rescinded after a positive result. Three months later, an EEOC charge alleged discriminatory testing practices. During discovery, the employer was ordered to produce all documentation related to the test , including proof that records were created at the time of testing, not assembled after the charge was filed.
An insurance carrier audited the company's drug-free workplace program across four locations to determine eligibility for a workers' comp premium discount. The auditor requested 12 months of records from all sites. Inconsistent formats, missing fields, or unverifiable timestamps would disqualify the program entirely.
The difference between a defensible record and a liability is whether the documentation was structured, timestamped, and cryptographically locked at the time of the event.
Purpose-built for workforce drug testing programs. One avoided dispute covers years of protection.
Essential documentation for employers running straightforward testing programs with standard record-keeping needs.
SHA-256 cryptographic sealing, chain-of-custody audit trails, and WORM evidence storage for organizations that need dispute-ready records.
Both plans include a free trial period. No credit card required to start.
Every record sealed with TestLedger carries a cryptographic timestamp and tamper-evident hash at the moment of collection. When documentation is demanded, it is already structured, signed, and verifiable.
