What a cutoff describes
A cutoff is a stated threshold associated with a particular screening test and analyte. It is part of the test configuration—not a universal value shared by every brand, specimen type, or method. A result at or above a screening threshold is interpreted according to that product’s instructions; it is not, by itself, a complete clinical or workplace determination.
A product page may list cutoff text in the format supplied by its source record. Compare the label and units exactly as shown. Do not convert, rank, or interpret a number when the product documentation does not establish what it means.
Compare like with like
Before choosing a product, identify the analytes your organization requires and the specimen format the intended workflow supports. Then compare the specific product’s analyte list, cutoff configuration, package quantity, and manufacturer instructions. Similar product names do not guarantee the same targets or thresholds.
When a cutoff is absent, abbreviated, or inconsistent across records, pause the comparison and ask the supplier to confirm it. A purchasing page is not a substitute for the package insert or the organization’s written procedures.
Build a documented workflow
Organizations can document the selected test, source of its specifications, staff training, handling steps, and the process for responding to a presumptive result. Use the instructions supplied for that exact product and keep them with the local procedure. Do not generalize a cutoff into a detection window or a conclusion about an individual.
For federally regulated workplace programs, consult current agency guidance and the requirements that apply to that program. Those requirements are not interchangeable with every treatment, recovery, or private workplace workflow.
