Batch Release, Quarantine and Rejection
Receipt, quarantine, release and rejection describe different decisions about material. To establish a Knockout Labs lot’s status, request the applicable specification, available test reports and recorded disposition. A stock indication or payment confirmation does not answer that question.
Read the state with its supporting record
| State or event | Record that makes it meaningful | Question to resolve |
|---|---|---|
| Receipt | Product, lot, container and receipt details | What material actually arrived? |
| Quarantine or restricted use | Reason, affected material and the control applied | What prevents use while the question remains open? |
| Evidence review | Applicable specification and the results reviewed | Which requirements were assessed? |
| Release | Dated decision tied to the material and criteria | Who authorised the disposition and on what basis? |
| Rejection or other disposition | Decision, reason and affected quantity | What happened to material that was not accepted? |
These are useful document distinctions, not confirmation of a universal Knockout Labs workflow. A process diagram cannot demonstrate that a particular lot passed through each stage. The sourcing and release page identifies the questions to put to support about the actual supply record.
Compare like with like
Use the specification that applies to the material, including its identity, form and reporting basis. A result should be compared with the corresponding criterion, rather than with a threshold taken from another product or a general website statement. Acceptance criteria and out-of-specification results explains this comparison.
ICH Q6A describes specifications through tests, procedures and acceptance criteria. ICH Q7 discusses laboratory and release records within pharmaceutical manufacturing. These sources clarify the record logic; they do not establish a Knockout Labs certification or quality system. [1] [2]
Separate a failed result from missing evidence
“No identity result supplied” and “identity result does not match the specification” are different findings. Record the first as an unresolved evidence request and the second as the actual reported discrepancy. Neither should be rewritten as a reassuring general statement about the batch.
For example, a fictional report may contain a satisfactory purity result while the container label and report show different lot identifiers. The purity result does not resolve the mismatch. Retain both identifiers and ask for the documented relationship or correction. Do not edit the original report yourself.
The certificate red-flags guide helps frame questions about a generic or reused document without treating a warning sign as proof of failure.
Keep a retrievable decision trail
Retain the product and lot identifiers, document versions, review date, questions raised and the decision received. If a corrected report replaces an earlier one, preserve the relationship between versions. That allows a later reviewer to understand which evidence supported the decision at the time.
Use batch documentation for available records and technical support for a discrepancy or quality concern. Include the order reference, exact lot text and the specific issue. The quality hub and testing-methods guide provide interpretation routes; actual decisions still require actual records.
