Evaluation of HSGC procedure with 20% TEa (CLIA2019)

Concentration	u_trg	s_r	s_r/√(n^al) (A)	u_trg/3 (B)	Conclusion
Low	5.60	0.87	0.02	1.87	Good precision¹
Medium	13.4	0.61	0.02	4.47
High	26.8	1.31	0.03	8.93

¹ criterion (A) < (B) conclusion indicates ‘good precision’

Abbreviations: u_trg represents the target uncertainty; s_r is the standard deviation; and n_al denotes the unit for measurement.
