# Array sex validation The Sex validation column indicates whether the biological sex inferred from genomic data matches the sex information provided during case creation.\ This helps identify potential sample mix-ups or metadata errors before interpretation begins. Sex validation results: * Pass Reported sex matches the estimated sex * Fail\ A mismatch was detected between reported and estimated sex. * N/A\ QC file not available; validation could not be performed. {% hint style="warning" %} If the sex was marked as unknown during case creation, the system will display the predicted sex instead of a validation status. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
