What is a complete blood count?
Complete blood count (CBC) is a blood test that doctors can use to diagnose certain health conditions, monitor the progression of the disease or determine the infection. CBC measures the various molecules that make up blood and compare them to a scale of normal values for each molecule. The test is performed either in a medical office, laboratory or hospital and requires a blood sample, often drawn from the arm using a needle. It takes very little time to run blood, but the results can take several days depending on the laboratory used to perform the analysis.
Blood consists of three types of cells: red blood cells, white blood cells and plates. CBC calculates the amount of each of these cell types. The machine uses light detectors to analyze a small blood sample and counting the number of cells. Cell types are determined by analysis of cell structure, components and size.
The complete blood number generally analyzes all blood components contained in red and white cells and plates. The number of white cells will include not only in totalThe number of white cells, but will also look at different types of white cells that can be divided into five subsets. Neutrophils are infections fighting white cells and should be about half of the number of white cells. Low neutrophil levels can cause people to be more susceptible to infections and may indicate the presence of autoimmune disease. Other types of white blood cells are lymphocytes, basophils, monkeytes and eosinophils.
In complete blood, lymphocytes may be higher in certain types of infections, including viral infections, or it may indicate leukemia. Monocytes are usually evaluated when bacterial infection is suspected. Increased eosinophils may indicate parasitic infection.
Red blood cells are calculated and evaluated for their hemoglobin (HGB) value that carries oxygen from the lungs to the rest of the body. Lower than normal hemoglobin levels may indicate anemia that may be due to low iron levels or other diseases. Hematocrit (hCv) is measured as a percentage in relation to the total blood volume and is evaluated in complete blood numbers to determine internal bleeding, for example, traumatic damage during an accident or suspicion of ectopic pregnancy. HCV levels are commonly checked after operations that led to blood loss.
Inserts are evaluated in terms of size and number. Low numbers of platelets, called thrombocytennia, can cause excessive bleeding in cutting, bruises and heavier menstrual periods. The high numbers, called thrombocytosis, indicate a higher risk of stroke due to blood formation. The use of anticoagulants often reduces the volume of plates and doctors often order a complete blood number to make sure that the number of plates is dangerously low without Beomiming.
Complete blood count is compared to normal range. This range is different in children and there is a certain degree of difference between the numbers of men and women. Corresponding normal ranges often appear on the messageCh CBC.
The laboratory and the doctor will analyze the complete blood number for anything out of the range. In fact, patients do not actually see the CBC Lab report. However, patients may ask for a message display and ask your doctor to explain any anomalies.
