Interpreting the Complete Blood Count and Differential 0. By Diane Pyle, RNC on May 14, 2016 Coagulation, Hematology. What Does the CBC Test Analyze? The CBC tests for the amount of RBCs, hemoglobin, hematocrit, reticulocytes, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration.
polymerase chain reaction (PCR) test, which measures biomarkers in bone marrow or blood cells, especially blood cancer cells; Other tests might be necessary based on the results of the differential test and followup tests. High white blood cell counts may be due to inflammation, an immune response, or blood diseases such as leukemia. It is important to realize that an abnormal increase in one type of white blood cell can cause a decrease in the percentage of other types of white blood cells.
A complete blood count and hence blood counts are among the most commonly performed blood tests in medicine, However, certain abnormal cells in the blood may not be identified correctly, requiring manual review of the instrument's results and identification by other means (such as microscopy) of any abnormal cells the instrument could The manual differential quantifies the number of each specific WBC type as a percentage of the total white blood cell count calculated in a complete blood count (CBC).
Manual blood cell analysis is performed by a highly skilled lab technician whereas automated analysis is performed by a machine. Jan 14, 2015 Manual differential blood count: This is performed by visual examination of peripheral blood smear (blood films) by trained personnel.
[ 3 The automated differential blood count is less timeconsuming and less expensive than routine examination of blood smear. The blood smear is primarily ordered to evaluate blood cells when a CBC with differential, performed with an automated blood cell counter, indicates the presence of abnormal or immature cells.
A blood smear is often used as a followup test to abnormal results on a complete blood count (CBC) Make sure to follow all instructions completely to make Manual differential blood test results the test results are as accurate as possible.
Was a Full Differential Test Ordered? The Segs blood test is generally ordered when a complete blood count comes pack with a positive result for higher than normal white blood cells.
