Overview

A chronic elevated concentration of blood mature neutrophils is diagnostic for chronic neutrophilic leukemia (CNL). There are other blood, bone marrow and genetic tests which help the diagnosis of CNL

Laboratory Findings

A chronic elevated concentration of blood mature neutrophils is diagnostic for CNL.^[1]

Some patients with CNL may have:^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[1]^[8]^[9]^[10]

Blood tests:

Peripheral blood White blood cells (WBC) ≥25 ×10⁹/L
Segmented neutrophils plus band forms ≥80% of WBC
Myeloblasts rarely observed
Monocyte count <1 ×10⁹/L
Mild anemia
Thrombocytopenia

Bone marrow test:

Hypercellularity of bone marrow.
Neutrophil granulocytes increased in percentage and number
Normal neutrophil maturation
Myeloblasts <5% of nucleated cells

Blood chemistry tests:

Elevation of lactate dehydrogenase (LDH).

Blood vitamin analysis:

Elevation of vitamin B12

Genetic tests:

Mutations which may seen:
- CSF3R
- SETBP1
- ASXL1
- TET2
- EZH2
- KDM6A

Cytogenetic abnormalities which may seen:
- Trisomy 8
- Trisomy 21
- Deletion 11q
- Deletion 20q6
- Deletion Y
- Trisomy 7
- Trisomy 9
- Detection of JAK2V617F
