Leukocytes come in different types: Lymphocytes, Neutrophils (which can be segmented or banded), Monocytes, Basophils and Eosinophils. A differential leukocyte count means they count the ammount of each type of leukocyte, this can be expressed in percentage or absolut values.
This has a great value for medical diagnosis, since variations in different leukocytes can be indicative of certain diseases. For example, in HIV infection, the number of lymphocytes diminish progressively. Eosinophils can be high during allergic reactions or SOME parasitic infections. Large ammounts of neutrophils (with bands over 7%, which is called "left shift") can be found in bacterial infections. Any of the types could be increased in cases of leukemia or lymphoma. Although these changes are no definitive proof for any disease, they help the medic to arrive to a proper diagnosis.

CPT Code 85025- complete (CBC), automated (Hgb, Hct, RBC, WBC and platelet count) and automated differential WBC count.
85045 is a CPT Pathology and Laboratory / Hematology and Coagulation test procedure code for: Blood count; automated differential WBC count; reticulocyte, automated.
When the leukocyte count is high, the physician should suspect either an infection or cancer, as these are the two most common reasons for an elevated leukocyte count. Depending upon the rest of the physical examination and the results of the rest of the blood tests, your physician may already know which of the two it is.
A white blood cell count is the same as a total leukocyte count. In cows, the expected range in the white blood cell count is 4 to 12 x 10 to the power of 9 per liter. Depending on the lab doing the testing, a white blood cell count can range from 3.5 to 9 or 4.5 to 11 for adult humans.
Leukocytes are white blood cells. There are different kinds of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. During a differential leukocyte count, 100 white blood cells are counted on a Wright stained blood smear using a microscope and assigned to one type. The percent of leukocytes that fall into each type can be used to indicate what disease or condition a patient has. An increased number of neutrophils may indicate a bacterial infection. The presence of cancerous cells can also be determined.
Complete blood count with differential. Total leukocyte count gives the total number of white blood cells per microliter of blood. The differential count gives the percentage of the various types of white blood cells like neutrophils, lymphocyts and eosinophils.A CBC is a complete blood count.It contains:RBC - number of red blood cellsMCV - average volume of individual red blood cellsMCHC - average amount of hemoglobin per red blood cellRDW - the average size of the red blood cellHemoglobinHematocritWBC - number of white blood cells.If it is ordered with a differential, then they want the lab to break down the different types of white blood cells, such as neutrophils, lymphocytes, monocytes, eosinophils, as monocytes.Different types of diseases cause a rise in the different types of WBCs, so a differential can often be useful in narrowing down a diagnosis.
