# Call rate

The Call rate field displays the percentage of loci on the array for which a genotype call was successfully made.

Call rate is one of the key metrics used to determine array sample [quality](https://help.connected.illumina.com/emedgene/emedgene-analyze-manual/reviewing_a_case/lab_tab/sample-quality-section/array-sample-quality-metrics/array-sample-quality), alongside [log R deviation](https://help.connected.illumina.com/emedgene/emedgene-analyze-manual/reviewing_a_case/lab_tab/sample-quality-section/array-sample-quality-metrics/log-r-deviation).

A high call rate indicates a high-quality sample and successful genotyping. Low call rates can signify problems with the DNA sample (poor quality or quantity) or issues during the array processing.
