The TRUE METRIX
®
PRO System was also tested by
healthcare professionals at a research center. The data
was compared to parallel results obtained on a Yellow
Springs Instrument (YSI). The table below shows how
often TRUE METRIX

PRO Blood Glucose System venous
values obtained by healthcare professionals achieve the
accuracy goals.
Venous samples drawn into sodium heparin anticoagu-
lant tubes.
Venous Blood < 75 mg/dL
Venous Blood ≥ 75 mg/dL
Within ±5 mg/dL 5/6 = 83.3%
Within ±10 mg/dL 6/6 = 100%
Within ±15 mg/dL 6/6 = 100%
Within ±5% 20/106 = 18.9%
Within ±10% 60/106 = 56.6%
Within ±15% 101/106 = 95.3%
Within ± 20% 106/106 = 100%
