Reference range

Reference ranges are laboratory- and methodology-specific. CD14 is expressed primarily on monocytes and macrophages; typical relative expression may be reported as percentage of total leukocytes or absolute count. Consult individual laboratory reference intervals.N/A

Specimen: serum

No special patient preparation required. Fasting is not necessary. Patients should be well-hydrated, and recent immunosuppressive therapy, chemotherapy, or corticosteroid use should be documented as these may affect monocyte counts.
