Which of the following CCF errors is classified as a 'fatal flaw' that cannot be corrected and requires test cancellation?
Answer: There is no specimen bottle sealed with a tamper-evident seal
An unsealed specimen — meaning no tamper-evident seal was applied — is a fatal flaw because specimen integrity cannot be confirmed.
How should a collector correct an error made while completing the CCF at the time of collection?
Answer: Draw a single line through the error, write the correction, and initial and date it
Errors on the CCF are corrected by drawing a single line through the mistake, writing the correct information, and initialing and dating the change.
A collector omits their signature from the CCF collector certification. This is considered what type of flaw?
Answer: A correctable flaw that can be remedied by a signed statement
A missing collector signature is a correctable flaw; the collector can submit a dated, signed corrective statement explaining the omission.
Who has authority to determine whether a CCF discrepancy is a fatal flaw vs. a correctable flaw?
Answer: The Medical Review Officer (MRO)
The MRO makes final determinations on whether CCF errors are fatal or correctable and whether a corrective statement resolves the discrepancy.
When an MRO identifies a correctable flaw in the CCF, what must the collector provide to resolve it?
Answer: A signed and dated written statement explaining what actually occurred during the collection
The collector must provide a signed, dated corrective statement describing what happened to explain or correct the identified flaw.
If the laboratory discovers a CCF specimen ID number that does not match the specimen bottle label upon accessioning, how is the test result reported?
Answer: As cancelled, and the MRO and employer are notified
A specimen ID mismatch is a fatal flaw; the lab must report the test as cancelled and notify the MRO.
An employer receives a CCF where the collection date is missing. The MRO classifies this as a correctable flaw. Who is responsible for submitting the corrective statement?
Answer: The collector or collection site
The collector or collection site must provide a corrective statement supplying the missing date based on their records.
