==Overview==
==Overview==
[[Laboratory]] findings consistent with the diagnosis of chronic neutrophilic leukemia (CNL) include [[chronic]] [[neutrophilia]]. Mild [[anemia]], [[thrombocytopenia]], elevation of [[lactate dehydrogenase]] and [[vitamin B12]].
A chronic elevated [[concentration]] of [[blood]] mature [[Neutrophil|neutrophils]] is [[diagnostic]] for chronic neutrophilic leukemia (CNL). There are other [[blood]], [[bone marrow]] and [[genetic]] [[test]]<nowiki/>s which help the [[diagnosis]] of CNL.

*Increased creatinine in some cases.
*Elevation of [[lactate dehydrogenase]] (LDH).
*Increased liver enzymes in some cases.
 
==== Conventional cytogenetics and karyotyping: ====
* This test looks at chromosomes under a microscope.
* The chromosomes can best be seen when the cell is dividing, so a sample of [[blood]] or [[bone marrow]] must be grown ''in vitro'' so that the cells start to divide.
* The leukemia cells in all [[CML]] patients contain an abnormal [[chromosome]] called the [[Philadelphia (Ph) chromosome]], which looks like a shortened version of chromosome 22.
 
==== Fluorescent in situ hybridization (FISH): ====
* FISH is another way to look at chromosomes and is more precise than conventional cytogenetics because it uses fluorescent dyes that only attach to specific genes or parts of [[chromosomes]].
* In [[CML]], FISH can be used to look for specific pieces of the BCR-ABL [[gene]] on chromosomes.  


==== Polymerase chain reaction (PCR): ====
==== Blood vitamin analysis: ====
* This is a highly sensitive test that can be used to look for the BCR-ABL product in [[leukemia]] cells. PCR is useful for quantitation.
*Elevation of [[vitamin B12]]  
* It can be done on blood or bone marrow samples and can detect very small amounts of BCR-ABL, even when Philadelphia chromosome can not be detected with cytogenetic testing.
* It can be used after treatment to see if copies of the BCR-ABL gene are still present.
* If copies of this gene are found it means that the [[leukemia]] is still present.

* Mutations which may seen:
** [[CSF3R]]

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][8][9][10][11][12][13][14][15][16]

Blood tests:
