Reference Range Study for the Quantra QStat System

The objective is to determine the reference range intervals for the parameters reported by the Quantra System with the QStat Cartridge.

Study Overview

• Status: Completed
• Conditions: Coagulation Disorder
• Intervention / Treatment: Diagnostic test: Quantra System

Detailed Description

This is a multicenter, prospective, observational study of a healthy adult population with normal coagulation function to determine the reference range intervals for the parameters reported by the Quantra System with the QStat Cartridge. The threshold for the Clot Stability to Lysis (CSL) parameter will be determined from the CSL reference range.

• Study Type: Observational

Study Population

Adult volunteers with normal coagulation function, approximately equal numbers of males and females across three age group categories (18-30, 31-50 and >50 years). The racial and ethnic profiles will be representative of the populations at each site.
