Complete Blood Count (CBC) with Differential and Platelets

Regular price $40.00

The complete blood count (CBC) with differential and platelets panel is a standard test routinely run during annual exams. The CBC test evaluates three categories of blood cells—red blood cells, white blood cells and platelets. These cells can help provide important information about immune function, whether there may be an infection, blood disorders, nutritional deficiencies, your body's ability to form blood clots, bone marrow health and more.

More about this test

White Blood Cells

White Blood Cells (WBCs). There are five types of WBCs. All are important for fighting infections. High WBCs, or elevated amounts of specific WBCs, may indicate you’re fighting an infection or have inflammation somewhere in your body. Low numbers of WBCs may increase your risk for infections.

Differential. The differential measures the percentages of the different types of WBCs. It also shows if there are any abnormal or immature cells.

Red Blood Cells and Indices

Hematocrit (Hct). This results shows how much of your whole blood is made up of red blood cells. A low Hct may indicate blood loss (eg, from bleeding). Or it could point to possible iron deficiency anemia or other disorders. Dehydration or other disorders can cause an elevated Hct.

Hemoglobin (Hgb) is the protein in red blood cells that carries oxygen from your lungs to the rest of your body. Among other possible reasons for this, low Hbg can be caused anemia, lead poisoning and blood loss.

Mean corpuscular hemoglobin (MCH) measures how much hemoglobin your red blood cells have. Low MCV can occur with anemia, lead poisoning and rheumatoid arthritis. A high MCV implies your red blood cells are larger than normal and can point to possible deficiencies in vitamin B12 and folic acid, liver disease or other potential underlying causes.

Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average concentration of hemoglobin inside a single red blood cell.

Mean corpuscular volume (MCV) is the average size of your red blood cells. MCV increases RBCs get bigger. This can occur when you have low vitamin B12 or folic acid. A low MCV can indicate other types of anemia, such as iron deficiency anemia.

Red blood cells (RBCs). RBCs play the vital role of delivering oxygen to tissues throughout your body and removing carbon dioxide from cells. Once the carbon dioxide is picked up the RBCs, they carry this toxin your lungs where the carbon dioxide is breathed out, thus removing it from your body. Too few RBCs can indicate you have anemia or other diseases and cause fatigue, depression and shortness of breath. Elevated RBCs can cause problems with blood flow and increase your risk for blood clots, heart attack, stroke, enlarged liver and spleen.

Red cell distribution width (RDW) indicates how much the size of your red blood cells vary. Red blood cells last for about 90 days. Young RBCs that have just been produced by your bone marrow are small and they get larger as they mature. An elevated RDW is one result doctors look at in determining if you have anemia and what type of anemia it might be.

Platelets are cell fragments that play a role in blood clotting. Too few platelets may mean you have a higher risk of bleeding. Too many platelets mean you have an increased risk for blood clots, heart attack and stroke.
