What Your CBC Blood Test Results Say About Your Health

Feb 03, †∑ This test tells how much of your blood is made up of red blood cells. A low score may be a sign that you donít have enough iron, the mineral that helps your body make red blood cells. A high. Feb 11, †∑ The complete blood count, or CBC, lists a number of many important values. Typically, it includes the following: White blood cell count (WBC or leukocyte count) WBC differential count; Red blood cell count (RBC or erythrocyte count) Hematocrit ; Hemoglobin (Hbg) Mean corpuscular volume (MCV) Mean corpuscular hemoglobin (MCH).

To determine your general health status; to screen for, diagnose, or monitor any one of a variety of diseases and conditions that affect blood cells, such as how to prepare for gre and toeflinfectioninflammationbleeding disorder or cancer. As part of a routine medical exam; when you have signs and symptoms that may be related to a condition that affects blood cells; at regular how to save a google map as a pdf to monitor treatment or disease status or when you are receiving treatment known to affect blood cells.

The CBC can how to use morrowind mods your overall health and detect a variety of diseases and conditions, such as infectionsanemia and leukemia. Blood cells are produced and mature primarily in the bone marrow and, under normal circumstances, are released into the bloodstream as needed.

The three types of cells evaluated by the CBC include:. Red blood cells, also called erythrocytes, are produced in the bone marrow and released into the bloodstream when they mature. They contain hemoglobin, a protein that transports oxygen throughout the body. The typical lifespan of an RBC is days.

Thus, the bone marrow must continually produce new RBCs to replace those that age and degrade or are lost through bleeding. RBCs normally are uniform in size and shape, but their appearance can be affected by a variety of conditions, such as vitamin B12 and folate deficiencies and iron deficiency. An example of a common condition affecting RBCs is anemia, which results from low red blood cell counts and low hemoglobin.

Various diseases can lead to anemia, so additional cbc values and what they mean are often needed to determine the cause. White blood cells, also called leukocytes, are cells that exist in the blood, the lymphatic systemand tissues and are an important part of the body's natural defense immune system.

They help protect against infections and also have a role in inflammationand allergic reactions. There are five different types of WBCs and each has a different function.

They include neutrophilslymphocytesbasophilseosinophilsand monocytes. WBCs are present in the blood at relatively stable numbers. However, these numbers may temporarily shift higher or lower depending on what is going on in the body.

For instance, an infection can stimulate your how to uninstall mcafee family protection marrow to produce a higher number of neutrophils to fight off a bacterial infection.

With allergies, there may be an increased number of eosinophils. An increased number of lymphocytes may be produced with a viral infection. In certain diseases, such as leukemia, abnormal immature or mature white cells may rapidly multiply. Platelets, also called thrombocytes, are actually tiny cell fragments that circulate in blood and are essential for normal blood clotting.

When there is an injury and bleeding begins, platelets help stop bleeding by cbc values and what they mean to the injury site and clumping together to form a temporary plug. They also release chemical signals that attract and promote clumping of additional platelets and eventually become part of a stable blood clot at the site of the injury that remains in place until the injury heals.

If you have a disease or condition that causes low platelets thrombocytopenia or dysfunction of platelets, you may be at an increased risk of excessive bleeding and bruising. An excess of platelets thrombocytosis can cause excessive clotting. For more information, see the article Platelet Count. A CBC is typically performed using an automated instrument how to treat itchy eyes measures various parameters, including cell counts and the physical features of some of the cells.

A standard CBC includes:. CBC results that are outside the established reference intervals may indicate the presence of one or more diseases or conditions. Typically, other tests are performed to help determine the cause of abnormal results.

Often, a blood smear will be examined using a microscope. A trained laboratory professional will evaluate the appearance and physical features of the blood cells, such as size, shape and color, noting any abnormalities that may be present. This information gives the healthcare practitioner additional clues as to the cause of abnormal CBC results.

The complete blood count CBC is often used as a broad screening test to determine your general health status. A CBC may be used to:. The CBC is a very common test. You may have a CBC performed when you have a routine health examination. The test may be ordered when you have fatigue or weakness, how to use a medela hand breast pump easy bruising or bleeding, or when you have signs and symptoms suggesting an infection or inflammationto name a few examples.

Likewise, if you are being treated for a blood-related disorder, then a CBC may be performed frequently to determine if the treatment is effective. Some therapies, such as chemotherapyhow to pick a domain name affect bone marrow production of cells. Some medications can decrease WBC counts overall. A CBC may be ordered on a regular basis to monitor these drug treatments.

A healthcare practitioner typically evaluates and interprets results from the components of the CBC together. Depending on the purpose of the test, a number of additional or follow-up tests may be ordered for further investigation.

For additional how to clean vomit from wool carpet, see the tables in the section Details on CBC Results below that briefly and generally explain what the result for each component of the CBC may mean.

To see an example of a CBC lab report, see this sample report. Some automated hematology analyzers report the total number of immature granulocytes IG present in your blood sample.

Immature granulocytes are white blood cells that have not fully developed before being released from the bone marrow into the blood.

They may include metamyelocytes, myelocytes, and promyelocytes. These cells are normally only present in the bone marrow because they are precursors of neutrophils, the predominant type of white cells in blood.

The presence of immature granulocytes in the blood may occur in various diseases, such as infection or a blood cancer, and thus will often prompt further investigation, which may include additional how to make short ribs testing.

IPF is the relative number of newly released young platelets also called reticulated platelets in the blood. Platelets are produced in the bone marrow and are normally not released into the bloodstream until they have matured.

When platelet numbers in the blood are low thrombocytopeniait stimulates the bone marrow to produce platelets faster. When the need is great and when production cannot keep up with "demand," then an increased number of young platelets will be present in the bloodstream.

This IPF test result would be one of the values reported when blood is evaluated using an automated hematology analyzer. The IPF may be used to help a healthcare provider determine the likely cause of your thrombocytopenia:. Lab test results including platelet count and IPF can also help determine if you need a platelet transfusion and help monitor bone marrow recovery, such as after a bone marrow transplant.

Other uses are being studied and the test's ultimate clinical utility has not yet been well determined. The hemoglobin inside of reticulocytes can be measured and reported as either a mean reticulocyte hemoglobin content CHr or a reticulocyte hemoglobin equivalent Ret-Hedepending upon the test method used.

This test result would be one of the values reported when blood is evaluated using an automated hematology analyzer. Reticulocytes are "young" red blood cells that are released by the bone marrow. They exist in blood for only days before becoming fully mature. The amount of hemoglobin inside of reticulocytes can help determine your body's iron status, particularly the availability of iron to be incorporated into hemoglobin in developing red blood cells in the bone marrow, within the past few days.

This makes the test useful in identifying functional iron deficiency in certain clinical conditions e. It depends on the results that are abnormal and the suspected disease or condition as well as your medical history and findings from your physical examination.

Your healthcare provider may request that a blood smear examination be done. Other general tests to check your health and to look for possible causes may include a comprehensive metabolic panel CMP.

A few other general examples include:. When a serious condition such as leukemialymphomamyelodysplasia or another bone marrow disorder is suspected, then a bone marrow aspiration and biopsy may be necessary. Talk to your healthcare provider about the results of your CBC, whether additional tests are necessary, and why. Many different conditions can result in increases or decreases in blood cell populations. Some of these conditions may require treatment, while others may resolve on their own.

A CBC, also known as a complete blood count, is a blood test commonly performed before and after surgery.

This test measures the types of blood cells that are in your blood and how many appear, allowing your provider to see if your blood is normal or if there are signs of a problem. The CBC is very useful because it can indicate many different common problems that occur in patients during surgery and during their recovery.

For this reason, a CBC may be drawn prior to surgery to "establish a baseline" for comparison with labs drawn after surgery. This way, it will be more obvious if there is a large change after surgery, or if something very serious like bleeding is happening during the hours and days after surgery.

This test may reveal signs of infection , dehydration, anemia , the need for a post-surgery transfusion and even chronic conditions, such as blood cancers. While these tests are often done before and after surgery, they are also done frequently as part of a routine physical when there is no apparent health problem. This is considered a screening and is done to catch problems in the early stages before they become serious.

A CBC is one of the most common blood tests done in health care and is almost always a part of routine blood work. Blood can be drawn from a vein, or if you have a special IV inserted for surgery, it may be drawn from that line. Blood is typically drawn from a blood vessel directly into a special type of test tube that prevents it from clotting. It is then sent to a lab for processing. Keep in mind that "normal" values can vary slightly based on simple changes such as the elevation at which you live.

Other factors which can affect values are hydration status and use of certain medications. Different labs also have slight differences in the "normal ranges. The information and potential diagnosis listed for high and low levels in the following paragraphs is just a list of possible causesóit doesn't mean you have any of these problems.

Do not assume anything about your blood tests without speaking to your provider as interpreting the results is both an art and a science and this article cannot replace the extensive education that providers receive.

Red blood cells carry oxygen to the body. Low results can indicate blood loss, problems with the bone marrow, leukemia, and malnutrition. High results can indicate heart problems, kidney disease, over transfusion and dehydration. These cells are the infection-fighting portion of the blood and play a role in inflammation. A low count can indicate bone marrow problems or other issues preventing the body from making enough of these blood cells, chemical exposure, autoimmune disease, and problems with the liver or spleen.

High levels can indicate the presence of tissue damage burns , leukemia and infectious diseases, or the use of certain medications such as steroids. This is the percentage of the blood that is composed of red blood cells. Low hematocrit levels can indicate anemia, blood loss, bone marrow problems, malnutrition and more. High levels can indicate dehydration, polycythemia vera, smoking, living at a high altitude and heart diseases that are present at birth.

Hemoglobin is a protein on red blood cells that carries oxygen. Too few red blood cells is called anemia. Low levels may indicate blood loss, caused by trauma, surgery, injury or possibly a long-term but small amount of bleeding in the body, such as an ulcer in the stomach. It can also indicate an inability to make enough blood, which is often caused by a deficiency in iron, B12 or folate.

Platelets are the part of the blood that makes the blood clot. Low levels may indicate the person is receiving chemotherapy, hemolytic anemia, the presence of a replacement heart valve , leukemia or a recent blood transfusion. High levels can be caused by anemia, specific types of cancer, polycythemia vera, a recent surgery to remove the spleen and other health issues. The CBC is a very useful test, but not as easy to interpret as you may believe, as there are many things to take into account when determining if there is a problem and what should be done about it.

For example, a lower hemoglobin after surgery than before may indicate blood loss, but it takes a full understanding of the procedure that was done to know how much blood loss likely occurred during surgery, and if the changes on the labs indicate a major problem or a routine recovery.
