Checking a CBC is helpful in making the diagnosis of a large number of medical conditions ranging from infections to the causes of bleeding.

Why do doctors check CBC?

With cancer, a complete blood count (CBC) is often checked at the time of diagnosis, and to follow the levels of blood cells during treatment. Chemotherapy interferes with cell division in rapidly dividing cells such as cancer cells but also affects rapidly dividing cells in the bone marrow.

What is it called when you have low red blood cells?

A low level of red blood cells during cancer treatment is called chemotherapy-induced anemia and can occur due to blood loss from surgery as well as the effect of chemotherapy on the production of red blood cells in the bone marrow.

Can CBC tell you how active your platelets are?

Unfortunately, a CBC can look at numbers, but cannot tell us how "active" the platelets are - someone may still be predisposed to bleeding with a normal platelet count. Platelet count 150,000-400,000/dL 1 .

A red blood cell count that's higher than normal (erythrocytosis), or high hemoglobin or hematocrit levels, could point to an underlying medical condition , such as polycythemia vera or heart disease.

How are hemoglobin and hematocrit related?

The results of your red blood cell count, hemoglobin and hematocrit are related because they each measure aspects of your red blood cells. If the measures in these three areas are lower than normal, you have anemia. Anemia causes fatigue and weakness.

Each of the cells in the WBC differential also has specific functions that are important to note when analyzing the results of a complete blood count. For example, eosinophils may be involved in allergic reactions.

What is the function of red blood cells?

Red blood cells are a vital part of the oxygen transport system in the body . The hemoglobin molecule is a complex protein structure that exists within the red blood cells and is the physical carrier of oxygen from the lungs to all other parts of the body.

What is the differential of WBC?

The white blood cell (WBC) differential refers to the number of the different types of white blood cells seen in the blood.

How to count white blood cells?

To count white blood cells, the sample is diluted using a fluid containing a compound that lyses red blood cells, such as ammonium oxalate, acetic acid, or hydrochloric acid. Sometimes a stain is added to the diluent that highlights the nuclei of white blood cells, making them easier to identify.

Why is a complete blood count performed before surgery?

The complete blood count has specific applications in many medical specialties. It is often performed before a person undergoes surgery to detect anemia, ensure that platelet levels are sufficient, and screen for infection, as well as after surgery, so that blood loss can be monitored.

How is blood collected?

The sample is collected by drawing blood into a tube containing an anticoagulant —typically EDTA —to stop its natural clotting. The blood is usually taken from a vein, but when this is difficult it may be collected from capillaries by a fingerstick, or by a heelprick in babies. Testing is typically performed on an automated analyzer, but manual techniques such as a blood smear examination or manual hematocrit test can be used to investigate abnormal results. Cell counts and hemoglobin measurements are performed manually in laboratories lacking access to automated instruments.

What does the red blood cell indices indicate?

The red blood cell indices, which indicate the average size and hemoglobin content of red blood cells, are also reported, and a white blood cell differential, which counts the different types of white blood cells, may be included.

What is manual blood smear?

Approximately 10–25% of samples require a manual blood smear review, in which the blood is stained and viewed under a microscope to verify that the analyzer results are consistent with the appearance of the cells and to look for abnormalities.

What is the purpose of the red blood cell differential?

The red blood cell indices can provide information about the cause of a person's anemia such as iron deficiency and vitamin B12 deficiency, and the results of the white blood cell differential can help to diagnose viral, bacterial and parasitic infections and blood disorders like leukemia.

Why are blood samples inaccurate?

If the sample is visibly clotted, which can be caused by poor phlebotomy technique , it is unsuitable for testing, because the platelet count will be falsely decreased and other results may be abnormal. Samples stored at room temperature for several hours may give falsely high readings for MCV, because red blood cells swell as they absorb water from the plasma; and platelet and white blood cell differential results may be inaccurate in aged specimens, as the cells degrade over time.

What is the normal hemoglobin level?

Normal is 25 to 35 picograms. Mean corpuscular hemoglobin concentration (MCHC) measures the concentration of hemoglobin in red blood cells. Normal is 32% to 36%.

Where are blood cells made?

Most types of blood cells are made in the bone marrow. The bone marrow is the soft, spongy tissue found in the center of the large bones like the pelvic bones, the breast bone, and the long leg bones. All cells made in the bone marrow start out as a single kind of cell called a stem cell.

Why is my WBC low?

A low WBC count may be due to chemotherapy, a viral infection, a toxic reaction, or a process in the bone marrow that limits the body’s ability to make normal WBCs. A high WBC count may result from an infection or leukemia. A person is at an increased risk of infection if his/her WBC count drops below 1,000 cells per microliter.

When do platelets decrease?

Platelet counts decrease just before a woman menstruates. A count below 50,000 can result in bleeding; below 5,000, patients are at risk of dangerous bleeding.

What is the function of red blood cells?

Blood cells. Red blood cells, also called erythrocytes, contain hemoglobin that gives red blood cells their color and carries oxygen from the lungs to the tissues. If the number of red blood cells is low, a person may feel tired or short of breath. The white blood cells, or leukocytes, are part of the body's immune system.
