Why Does A Doctor Order A CBC With Differential?

Can CBC detect viral infection?

A CBC test usually includes: White blood cell (WBC, leukocyte) count.

White blood cells protect the body against infection.

If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it..

What does a CBC with differential test for?

The amount of hemoglobin (substance in the blood that carries oxygen) and the hematocrit (the amount of whole blood that is made up of red blood cells) are also measured. A CBC with differential is used to help diagnose and monitor many different conditions, including anemia and infection.

How can you tell the difference between a viral and bacterial infection on a CBC?

For example, if you have a bacterial infection, you will have an increase of neutrophils and a decrease in lymphocytes. Conversely, if you have a viral infection, you will have a decrease in neutrophils and an increase in lymphocytes.

What is a normal differential count?

Reference ranges for differential white blood cell counts are as follows : Neutrophils – 2500-8000 per mm3 (55-70%) Lymphocytes – 1000-4000 per mm3 (20–40%) Monocytes – 100-700 per mm3 (2–8%) Eosinophils – 50-500 per mm3 (1–4%)

Is WBC count elevated in viral infection?

Neutrophils, which account for about 70% of white blood cells, can increase in response to bacterial infections as well as to physical or emotional stress. A high lymphocyte count may occur when there is a viral or bacterial infection. Increased monocytes can indicate chronic inflammation.

How long does a CBC with differential take?

This occurs mostly during the WBC Differential phase of the analysis and can prolong the time it takes to receive the results. In most cases, emergency CBCs are reported back in less than an hour. Results of routine CBCs for hospital in-patients are made available in three to six hours.

How do you read a CBC with differential?

When the white count is abnormal, the differential segment can measure the percentage of the various types of white cells present. Differential counts add up to 100 percent. The differential usually includes neutrophils, bands, eosinophils, monocytes and lymphocytes.

Do lymphocytes increase with viral infection?

The number of virus-infectible lymphocytes was increased in patients with bacterial infections but not in patients with viral infections. These studies suggest that subpopulations of human peripheral blood lymphocytes vary in response to different types of infectious agents.
