The blood differential is a part of a complete blood count (CBC) test, which provides important information about the different types of cells in the blood. It helps healthcare professionals diagnose certain diseases and monitor overall health.
During a blood differential test, a small sample of blood is taken from the body and analyzed in a laboratory. The sample is examined under a microscope, and the different types of white blood cells are counted and identified. These white blood cells play a crucial role in the body’s immune system, and abnormalities in their numbers or functions can indicate various health conditions.
There are several types of white blood cells, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each type has a specific function and is responsible for different aspects of the immune response. By analyzing the percentage of each type of white blood cell, healthcare professionals can determine if there is an imbalance or abnormality that may indicate an underlying health issue.
A blood differential test is especially helpful in diagnosing and monitoring certain diseases, such as infections, autoimmune disorders, and leukemia. Certain diseases may cause an increase or decrease in specific types of white blood cells, and by examining the blood differential, healthcare professionals can get important clues about the presence and progression of these diseases.
What is it used for
The blood differential is a test that is used to analyze the different types of cells in the body’s blood. It is commonly performed as part of a complete blood count (CBC). The test helps diagnose and monitor various health conditions and diseases.
Diagnose and monitor diseases
By examining the different types of cells present in the blood, the blood differential can provide valuable information about a person’s health. For example, higher levels of certain white blood cells may indicate an infection or inflammation in the body. On the other hand, lower levels of certain cells may be indicative of conditions such as anemia.
The blood differential test can also help identify certain blood disorders, such as leukemia or lymphoma. These disorders involve abnormal cell growth in the blood and can be detected through changes in the blood cell counts and ratios.
Assess overall health
In addition to diagnosing specific diseases, the blood differential can also provide an overall assessment of a person’s health. By analyzing the different cell types and their ratios, doctors can get insights into the functioning of various body systems.
For example, a high number of red blood cells may indicate a condition called polycythemia, which can put a strain on the heart and circulatory system. Similarly, abnormalities in the ratio of different white blood cells may indicate immune system disorders or certain types of cancer.
Overall, the blood differential test provides valuable information about the health of an individual and helps doctors make informed decisions regarding their treatment and care.

What happens during a blood differential test
A blood differential test is a part of a complete blood count (CBC) that provides information about the types and numbers of cells in your blood. This test helps healthcare professionals assess your overall health and diagnose certain conditions or diseases.
During a blood differential test, a small sample of your blood will be taken. The sample is usually collected from a vein in your arm using a needle. There may be some discomfort or a slight prick when the needle is inserted, but it is generally a quick and relatively painless procedure.
Once the blood sample is collected, it is sent to a laboratory for analysis. In the laboratory, the blood sample is examined under a microscope to count and classify the different types of cells present in your blood.
Types of cells examined in a blood differential test
- Red blood cells (erythrocytes): These cells carry oxygen throughout the body. Abnormalities in the number or quality of red blood cells can indicate various conditions, such as anemia or sickle cell disease.
- White blood cells (leukocytes): These cells play a crucial role in the body’s immune response, fighting off infections and diseases. An abnormal increase or decrease in the number of white blood cells can indicate an infection or other medical conditions.
- Neutrophils: Neutrophils are a type of white blood cell that helps the body fight off bacterial infections. An increased or decreased neutrophil count can be a sign of an infection or inflammation.
- Lymphocytes: Lymphocytes are another type of white blood cell involved in the immune response. An increased or decreased lymphocyte count can indicate various conditions, including viral infections, autoimmune disorders, or certain cancers.
- Monocytes: Monocytes are white blood cells that help eliminate dead or damaged cells and fight off infections. Abnormal monocyte levels can be associated with chronic infections or inflammatory conditions.
- Eosinophils: Eosinophils are white blood cells involved in the body’s response to allergic reactions and parasitic infections. High eosinophil counts may suggest allergies or certain diseases.
- Basophils: Basophils are the least common type of white blood cell. They are involved in allergic reactions and the release of histamine. An increased basophil count may suggest allergies or certain types of leukemia.
By analyzing these different types of cells, a blood differential test can help healthcare professionals identify any abnormalities or imbalances in the blood that may indicate underlying health issues.

Australian National Genomic Information Service (ANGIS), including the database of BioManager, has been maintained for a long time by Peter Reeves, a professor at the University of Sydney.
Professor Reeves is internationally renowned for his genetic analysis of enteric bacteria. He determined the genetic basis of the enormous variation in O antigens. There can be more than an I00 form within a species and little overlap between related species. This variation is due to the reassortment of genes between O antigen genes and other gene clusters and the transfer of gene clusters between species. He showed that the 7th pandemic clone of Vibrio cholerae did not arise directly from the 6th pandemic clone, suggesting it arose from an environmental strain, with implications for the origins of this significant human pathogen.
