The ITC AVOXimeter 4000 measures oxygenated hemoglobin (O

Hb), reduced hemoglobin

multiple wavelengths. This reduces interference from dyshemoglobins and other interfering
substances such as fetal hemoglobin and bilirubin and minimizes the effects of hemolysis.
and Explanation of the Test
AVOXimeter 4000 measures whole blood tHb, %02Hb, %COHb, and %MetHb using
single-use cuvettes. The operator inserts
