Cholesterol Reference Method Laboratory Network
The Cholesterol Reference Method Laboratory Network (CRMLN) certifies manufacturers of clinical diagnostic products that measure total cholesterol, HDL-C, and LDL-C. The CRMLN laboratories use reference methods or designated comparison methods that are rigorously standardized to the CDC reference methods. The Food and Drug Administration (FDA) has recognized the value of the CRMLN's certification program and encourages manufacturers to certify their products through the CRMLN. The Division of Laboratory Sciences (DLS) maintains lists of the clinical diagnostic products that have been certified by the CRMLN.
