Abnormal manual differential

 · Principle. When blood samples are evaluated by the use of automated hematology analyzers, this analysis includes automated differentials. Specific criteria pertaining to normal, abnormal, and critical values have been programmed into the analyzers by the institution, and if the differentials do not meet these criteria, verification is necessary. This is done by performing manual Estimated Reading Time: 5 mins.  · This test is also known as Complete blood count (CBC) with differential, Leukocyte differential count, Differential, and White blood cell differential count. What Is A Blood Differential Test? This test detects immature or abnormal cells. Besides, it can even diagnose inflammation, infection, immunity disorder, and leukemia. The White blood cell differential test is often part of a Estimated Reading Time: 3 mins. A smear review will revert to a manual differential if it is estimated that there is greater than 5% immature WBCs (bands,metas,myelos,blasts etc.) or greater than 5% nucleated RBCs. (Note: If greater than 5 % nRBCs the WBC count from the instrument will have to be corrected as follows: Corrected WBC = obtained nucleated cell count x ( ÷ [nRBC + ]).

Specific criteria pertaining to normal, abnormal, and critical values have been programmed into the analyzers by the institution, and if the differentials do not meet these criteria, verification is necessary. This is done by performing manual differentials and further evaluating the peripheral smear. The manual differential, in which white blood cells are counted on a stained microscope slide, is now performed to investigate abnormal results from the automated differential, or upon request by the healthcare provider. The manual differential can identify cell types that are not counted by automated methods and detect clinically significant changes in the appearance of white blood cells.

The white blood cell (WBC) differential refers to the number of the different types blood count need further review to confirm certain abnormal values. A CBC with differential is used to help diagnose and monitor many different conditions, including anemia and infection. Also called blood cell count with. Though some automated hematology analyzers provide a differential count as Abnormally large cells of potential diagnostic importance also tend to be.
