com·plete blood count (CBC),

a combination of the following determinations: red blood cell count, white blood cell count, erythrocyte indices, hematocrit, differential blood count, and sometimes platelet count.

complete blood count

n. Abbr. CBC
The determination of the quantity of each type of blood cell in a given sample of blood, often including the amount of hemoglobin, the hematocrit, and the proportions of various white cells.

complete blood count (CBC)

a determination of the number of red and white blood cells per cubic millimeter of blood. A CBC is one of the most routinely performed tests in a clinical laboratory and one of the most valuable screening and diagnostic techniques. Most laboratories use an electronic counter for reporting numbers of red and white blood cells and platelets. Examining a stained slide of blood yields useful information about red cell morphological characteristics and types of white blood cells (WBCs). The normal red blood cell (RBC) count in adult males is 4.7 to 6.1 million/mm3. In adult females the normal RBC is 4.2 to 5.4 million/mm3. Each type of white blood cell can be represented as a percentage of the total number of white cells observed. This is called a differential count. The normal adult WBC count is 5000 to 10,000/cm3. Electronic blood counters also automatically determine hemoglobin or hematocrit and include this value in the CBC. See also differential white blood cell count, erythrocyte, hematocrit, hemoglobin, leukocyte.

(CBC) (kŏm-plēt' blŭd kownt)
A combination of the following determinations: red blood cell indices and count, white blood cell count, hematocrit, hemoglobin, platelets, and differential blood count.

Complete blood count (CBC)

A routine analysis performed on a sample of blood taken from the patient's vein with a needle and vacuum tube. The measurements taken in a CBC include a white blood cell count, a red blood cell count, the red cell distribution width, the hematocrit (ratio of the volume of the red blood cells to the blood volume), and the amount of hemoglobin (the blood protein that carries oxygen). CBCs are a routine blood test used for many medical reasons, not only for AIDS patients. They can help the doctor determine if a patient is in advanced stages of the disease.

com·plete blood count

(kŏm-plēt' blŭd kownt)
Laboratory-based combination of: red blood cell count, white blood cell count, erythrocyte indices, hematocrit, differential blood count, and often a platelet count.

The study samples were routine patient specimens that had a differential WBC count ordered by the clinician and a microscopic slide reviewed because one or more of the 5 flags of interest was triggered at the factory default settings.
The numeric value of each of the 5 differential WBC count-specific flag variables was extracted from the automated cell counter and incorporated into an Excel spreadsheet.
To increase the number of cases with actual leukemic blasts in the differential WBC count tests, we collected additional samples, flagged at factory-set criteria, which were ultimately confirmed by manual differential tests to harbor more than 1% blasts.
The breakdown of abnormalities observed in the manual differential WBC counts of the validation set (n = 378) was 4 samples (1.
Fourteen additional cases flagged at factory-default settings and proven, by manual differential WBC count, to harbor blast cells were analyzed.
In this study, we have described a method for optimizing flagging thresholds on an automated cell counter that allows laboratories to safely reduce the number of differential WBC counts that require preparation of a slide (review rate).
Overall, the optimized thresholds resulted in an improved PPV of each flag for either its particular abnormality or for any abnormality in the differential WBC count.
With these limitations, the efficiency rates of the differential WBC count flags in our study are very similar to those reported by Lacombe and colleagues (16) for the Cobas Argos 5 Diff (ABX/Roche Hematology Division, Montpellier, France) and the Technicon H2 (Technicon Instruments, Tarrytown, New York), and by Ruzicka and coworkers (17) for Sysmex XE-2100 instruments.
