Recently, a user submitted a question about the mandatory use of the 10_x rule on chemistry analytes as mandated by ISO 15189 through NABL:

"Specific criteria of accreditation of NABL India (for ISO 15189) say that 10x should be considered as a violation for clinical chemistry  and Immunoassay parameters. However we understand that Westgard rules consider it as a warning only. Please advise."

So, the central question is, does ISO 15189 mandate the use of the 10_x control rule?
