What is the difference between a hemogram and a cbc

More than one needle stick may be needed. Attach a tube to the needle to fill it with blood. Remove the band from your arm when enough blood is collected. Put a gauze pad or cotton ball over the needle site as the needle is removed. Put pressure to the site and then a bandage. How It Feels The blood sample is taken from a vein in your arm. Risks There is very little chance of a problem from having a blood sample taken from a vein.

You may get a small bruise at the site. You can lower the chance of bruising by keeping pressure on the site for several minutes. In rare cases, the vein may become swollen after the blood sample is taken. This problem is called phlebitis. A warm compress can be used several times a day to treat this.

Results A complete blood count CBC gives important information about the kinds and numbers of cells in the blood, especially red blood cells , white blood cells , and platelets. Normal The normal values listed here—called a reference range—are just a guide. High values Red blood cell RBC Conditions that cause high RBC values include smoking, exposure to carbon monoxide, long-term lung disease, kidney disease, some cancers, certain forms of heart disease, alcohol use disorder , liver disease, a rare disorder of the bone marrow polycythemia vera , or a rare disorder of hemoglobin that binds oxygen tightly.

Conditions that affect the body's water content can also cause high RBC values. These conditions include dehydration , diarrhea or vomiting, excessive sweating, and the use of diuretics. The lack of fluid in the body makes the RBC volume look high; this is sometimes called spurious polycythemia. White blood cell WBC, leukocyte Conditions that cause high WBC values include infection, inflammation, damage to body tissues such as a heart attack , severe physical or emotional stress such as a fever, injury, or surgery , kidney failure, lupus , tuberculosis TB , rheumatoid arthritis , malnutrition, leukemia , and diseases such as cancer.

The use of corticosteroids , underactive adrenal glands , thyroid gland problems, certain medicines, or removal of the spleen can also cause high WBC values. Platelets High platelet values may be seen with bleeding, iron deficiency, some diseases like cancer, or problems with the bone marrow. Anemia can be caused by heavy menstrual bleeding, stomach ulcers , colon cancer , inflammatory bowel disease , some tumours, Addison's disease , thalassemia , lead poisoning , sickle cell disease , or reactions to some chemicals and medicines.

A low RBC value may also be seen if the spleen has been taken out. A lack of folic acid or vitamin B12 can also cause anemia, such as pernicious anemia , which is a problem with absorbing vitamin B The RBC indices value and a blood smear may help find the cause of anemia. White blood cell WBC, leukocyte Conditions that can lower WBC values include chemotherapy and reactions to other medicines, aplastic anemia , viral infections, malaria , alcoholism, AIDS , lupus , or Cushing's syndrome.

A large spleen can lower the WBC count. Platelets Low platelet values can occur in pregnancy or immune thrombocytopenic purpura ITP and other conditions that affect how platelets are made or that destroy platelets. A large spleen can lower the platelet count. What Affects the Test Reasons you may not be able to have the test or why the results may not be helpful include: If the elastic band was on your arm a long time while the blood sample was taken. Taking medicines that can cause low platelet levels.

Some examples of the many medicines that cause low platelet levels include steroids, some antibiotics , thiazide diuretics, chemotherapy medicines, quinidine, and meprobamate. A very high white blood cell count or high levels of a type of fat triglycerides. These can cause falsely high hemoglobin values. Having an enlarged spleen , which may cause a low platelet count thrombocytopenia or a low white blood cell count. It measures several components of the blood that includes red blood cells RBC which carry oxygen, white blood cells WBC which fight infection, hemoglobin Hb which is the oxygen-carrying protein in red blood cells, hematocrit which is the proportion of red blood cells to the fluid component, or plasma, in the blood and platelets that help with blood clotting.
