How Often You Run Quality Control?

It is widely accepted that laboratories should perform QC at least every day of patient testing. However, is this the right QC frequency for every assay and for every laboratory? Is running QC once per day really sufficient? What is the "right" frequency for running QC samples in your laboratory?

There are various factors that you need to consider when deciding an appropriate QC frequency. A good place to start is by asking the right questions:

• Which assays are more stable compared to others? Which tests are higher risk and have a higher impact if results are erroneous?
• How many patient samples are you running in between QC evaluations?
• What is the time between QC evaluations?

If you ask the "right" questions, you'll get the "right" answers.
