Reference Values
% Monocytes of WBC: 1.0-6.6%
MO1 (classical monocytes): <94.0%
Supportive Data
Clinical Sensitivity and Sensitivity:
Thirty-two patients with untreated chronic myelomonocytic leukemia (CMML) were tested. Twenty-five of these patients had a percent classical monocyte (%MO1) result of greater than or equal to 94% (abnormal result), which correlated to a sensitivity of 78%.
One hundred one patients with non-CMML hematologic malignancies were also tested. Ninety of these patients had a %MO1 result of less than 94% (normal result), which correlated to a specificity of 89%.
In addition, 30 healthy donors also had a %MO1 result of less than 94% (normal result).
