List of reasons why integrity validation failed

Test	Reason for not passing	Solution
HPV genotyping	There was no comprehensive analysis of the combined thin-layer cytology results	Analyze the results associated with thin-layer cytology
Urea	The limit range was too wide	Reduce the limit range
Albumin	Review of the detection system produces an error	Specify the detection system
CBC	Test results were checked only on the same day as the barcode	Extend the backdating of the historical results
HBsAg HBsAb HBeAg HBeAb HBcAb	Not all composite mode scenarios were covered	Add a joint audit of the portfolio project results
Cortisol	There was no warning of abnormal rhythms	Add a rule about checking sampling time
