PreciMind Analytical Performance Intelligence System
PM-APIS · Multi-framework TEa resolution · Sigma · QC decision
Analytical Parameters
Enter method performance data. TEa is resolved automatically from the analyte database.
Between-run long-term imprecision. CLSI EP5-A3.
From EQA peer group or CRM. Signed percentage.
About PM-APIS
PM-APIS resolves TEa ambiguity by computing sigma across multiple frameworks simultaneously — CLIA (regulatory), and EFLM Biological Variation (minimum, desirable, optimal).
This answers: "Which TEa should I use?" and "How does TEa choice affect my analytical performance conclusion?"
