The CPRT four-layer framework (reagents, labor, equipment, overhead) built on CLSI GP11-A. How to use it for budget, capital, and contract negotiations.
Frequently Asked Questions
What is cost per reportable test (CPRT)?
The fully-considered cost of producing one reportable laboratory result, built up in four layers under the CLSI GP11-A framework.
What are the four CPRT layers?
Layer 1 is reagents and supplies; Layer 2 adds direct labor; Layer 3 adds equipment depreciation and maintenance; Layer 4 adds overhead. Each answers a different financial question.
Which layer for an insource vs send-out decision?
Usually Layer 2, reagents and supplies plus direct labor, when the analyzer is already on the floor.
Which layer justifies a new analyzer?
Layer 3, which adds equipment depreciation and maintenance across projected volume.
Which layer sets a charge-master price?
Layer 4, the fully loaded cost including overhead.
Does CLIA require CPRT?
No, but 42 CFR §493.1407 and §493.1445 make the laboratory director responsible for defending the laboratory's resource decisions.
