What are bands in a CBC?
Bands: These are occasionally referred to as “stabs” and are immature neutrophils which are released after injury or inflammation. The presence of bands indicates that an inflammatory process is occurring.
What is the normal range for bands?
Normal Blood Values
| Blood Counts | Per cu. Mm | Percent |
|---|---|---|
| Lymphocytes | 1,000-4,000 | 20-40% |
| Segmented neutrophils | 2,500-6,000 | 40-60% |
| Band neutrophils | 0-500 | 0-5% |
| Juvenile neutrophils | 0-100 | 0-1% |
What are SEGS and bands?
Polys (also known as segs, segmented neutrophils, neutrophils, granulocytes) are the most numerous of our white blood cells. These are the first line of defense against infection, killing invaders of the body. Bands (also known as stabs, segs or segmented bands) are immature polys.
Are band neutrophils bad?
Band neutrophil counts are unnecessary for the diagnosis of infection in patients with normal total leukocyte counts.
How are bands calculated?
To find out your ANC, multiply the percentage of neutrophils by the total number of WBCs ( in thousands). Neutrophils are sometimes called segs or polys, and young neutrophils may be called bands on your lab report. If bands are listed as a percentage of WBCs, add them to the neutrophils before multiplying.
What does a left shift mean on a CBC?
A “left shift” is a phrase used to note that there are young/immature white blood cells present. Most commonly, this means that there is an infection or inflammation present and the bone marrow is producing more WBCs and releasing them into the blood before they are fully mature.
What causes bands in the blood?
“Bandemia” is the term used to describe too many white blood cells being released by bone marrow into the bloodstream. When this occurs, it’s usually an indication that an infection or some inflammation is present.
What does it mean when your bands are high?
They are essential for fighting disease. That’s why your body produces them in excess during an infection. A normal band cell count is 10 percent or less. A high band count could provide an early suggestion that a serious infection is present.
What causes an increase of bands?
Elevation of the band count is not specific for infection, but may be secondary to inflammatory processes, tissue damage or necrosis, neoplasia, intoxication, metabolic abnormalities, hemorrhage, hemolysis or drugs.
What is normal band neutrophil count?
Band cells are an immature form of neutrophils, which are the most commonly produced white blood cell. They are essential for fighting disease. That’s why your body produces them in excess during an infection. A normal band cell count is 10 percent or less.

What does high bands indicate in blood?
An elevated concentration of band neutrophils in the blood is always the result of infection or inflammation. In the instance of infection, the source is likely bacterial.
What does increased bands in blood work mean?
High bands are due to presence of early forms of a type of white blood cells in the blood counts. This happens when there is a stress on the blood production due to infection, inflammation or sometimes due to blood cancers.
What do bands on white blood cell count mean?
A band cell, which is also called band neutrophil is a type of white blood cell. The test is used to confirm bacterial infection and sepsis. An increase in band cell count typically means that the bone marrow has been signalled to increase WBC production owing to an infection or inflammation in the body.
What are immature bands?
Immature cells: Bands are the immature white blood cells, their presence can mean many things, but we typically find them elevated in acute infection, in the sense that in an acute infection your bone marrow is pumping out so many white blood cells to fight infection that it start pumping out immature ones “bands”.
