# What is absolute differential?

## What is absolute differential?

Results of a differential are usually reported as absolute values of the five types of WBCs and/or may be reported as a percent of the total number of WBCs. Absolute values are calculated by multiplying the total number of WBCs by the percentage of each type of white cell.

## What does a differential blood count tell you?

A differential blood count gives the relative percentage of each type of white blood cell and also helps to reveal abnormal white blood cell populations (eg, blasts, immature granulocytes, and circulating lymphoma cells in the peripheral blood).

What is absolute and differential count?

The white blood cell differential count determines the number of each type of white blood cell, present in the blood. It can be expressed as a percentage (relative numbers of each type of WBC in relationship to the total WBC) or as an absolute value (percentage x total WBC).

How do you interpret absolute neutrophil count?

A healthy person has an ANC between 2,500 and 6,000. The ANC is found by multiplying the WBC count by the percent of neutrophils in the blood. For instance, if the WBC count is 8,000 and 50% of the WBCs are neutrophils, the ANC is 4,000 (8,000 × 0.50 = 4,000). When the ANC drops below 1,000 it is called neutropenia .

### What is a normal differential count for WBC?

Normal Results The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens. Talk to your provider about your test results.

### What is a normal differential count?

definition. In blood count. A differential blood count is the percentage of each type of white blood cell per 100 white cells counted; the white cells of a normal adult are about 55 percent neutrophils, 30 percent lymphocytes, and small percentages of eosinophils, basophils, and monocytes.

How high is too high for basophils?

A basophil count is considered high (basophilia) if the absolute basophil count is above 200 microliters or the percentage is greater than 2%. The absolute count range considered normal may vary to some extent in laboratories in different places, based on the local population.

How high is too high for monocytes?

Monocytosis or a monocyte count higher than 800/µL in adults indicates that the body is fighting an infection. Monocytosis or a monocyte count higher than 800/µL in adults indicates that the body is fighting an infection.

#### What if absolute neutrophil count is high?

If your neutrophil counts are high, it can mean you have an infection or are under a lot of stress. It can also be a symptom of more serious conditions. Neutropenia, or a low neutrophil count, can last for a few weeks or it can be chronic.

#### What is considered a high absolute neutrophil count?

A normal neutrophil level is between 1,500 and 8,000 neutrophils per microliter. A high neutrophil level is over 8,000 neutrophils per microliter.

How do you interpret absolute differential counts?

To interpret absolute differential counts, follow these steps. As a quality check, add up the absolute counts of the subtypes of cells and it should equal the total WBC.

How do you interpret absolute WBC counts?

Interpreting absolute WBC counts. The absolute count for a particular type of blood cell is the total white blood cell count multiplied by the differential percentage for that cell type. Neutrophilia is caused by increased marrow proliferation, redistribution among body neutrophil pools, stress and corticosteroids.

## How do you interpret a differential blood count?

Interpretation. Differential blood count is not a part of complete blood count (CBC) but is interpreted together with CBC to help support or exclude a suspected diagnosis. For example, the presence of anemia along with thrombocytopenia with a low or high white blood cell count may suggest bone marrow involvement by leukemia.

## What is an automated differential blood count?

The automated differential blood count is less time-consuming and less expensive than routine examination of blood smear. With the automated technique, thousands of white blood cells can be examined, whereas typically 100-200 white blood cells are examined by visual examination. Indications/Applications.
