# Array sample quality

The Quality status provides a quick assessment of array data reliability for each sample:

* High

  Call rate ≥ 0.99 and Log R dev ≤ 0.2
* Low\
  If either condition is not met
* N/A

  If the QC file not available

Use the Quality status to quickly screen whether a sample meets minimal QC thresholds before starting detailed interpretation.
