# 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.
