Hypertrophic Cardiomyopathy: The Time-Synchronized Relationship between Ischemia and Left Ventricular Dysfunction Assessed by Highly Sensitive Troponin I and NT-proBNP

Table 1

TNHS test repeatability and intralaboratory precision.

High-sensitivity troponin; (pg/ml; ng/l)	Assay output requirements
	Repeatability (within the same series) (CV (%))	Intralaboratory precision (total) (CV (%))
9-20	≤10%	≤12%
>20	≤10%	≤10%

Precision was assessed in accordance with the EP05-A3 protocol of the Clinical and Laboratory Standards Institute (CLSI): “Evaluation of Precision of Quantitative Measurement Procedures; Approved Guidelines—Third Edition” (CLSI Document EP05-A3).
