The above CBC report indicates that the platelet count for this patient is normal.īlood Chemistry Panel: The blood chemistry panel measures the levels of chemicals, enzymes, and organic waste products that are normally found in the blood. Platelets: Platelets are the cells that form blood clots that stop bleeding. This means that the patient has mild anemia and may be starting to notice symptoms. The hematocrit (HCT), another way of measuring the amount of Hb, is also low. The above CBC report indicates that the patient’s Hb count is 10.8, which is below the normal range of 14.0-18.0. Hemoglobin (Hb or Hgb): Hemoglobin is a protein in the red cell that carries oxygen. The above CBC report indicates that the patient has a red cell count of 3.5, which is lower than the normal range of 4.70-6.10, and therefore, shown in the flag column. Red blood cells: Red blood cells carry oxygen from the lungs to the rest of the body. For example, this patient’s ANC is 0.34, which equals (WBC) 1.5 x 23%. The ANC can be calculated by multiplying the total WBC by the percent of polymorphonuclear cells. When the ANC is less than 1,000, the risk of infection increases. The absolute neutrophil count (ANC) is a measure of the total number of neutrophils present in the blood. In the CBC report, neutrophils may be referred to as polymorphonuclear cells (polys or PMNs) or neutrophils. The low white cell count increases the risk of infection.Ībsolute neutrophil count: Neutrophils are the main white blood cell for fighting or preventing bacterial or fungal infections. The above CBC report shows that the patient’s total white cell count is 1.5, which is lower than the normal range of 4.0-10.5. White blood cells: White blood cells help protect individuals from infections. Different labs may use different reference intervals. Reference interval (or reference range) column: The reference interval shows the normal range for each measurement for the lab performing the test. Result column: The result column shows counts that fall within the normal range.įlag column: The flag column shows counts that are lower (“L”) or higher (“H”) than the normal range. Table 1: CBC with results and reference interval CBC You will want to pay careful attention to the results column, which shows any results that are normal and the flag column, which shows any results that are abnormal. It is important to understand not only which blood counts are being tested, but also how those results are reported. In the United States, the CBC is typically reported in the format shown in Table 1 below. The CBC measures the levels of the three basic blood cells: red blood cells, white blood cells, and platelets. There are two types of blood tests typically performed during cancer treatment: the complete blood count (CBC) and a blood chemistry panel. Also, the levels of some chemicals normally found in the blood may be either too high or too low as a result of the cancer or its treatment. The levels of blood cells, such as red blood cells, white blood cells and platelets, may be low in patients receiving treatment for cancer. Blood tests are used to measure the number of blood cells in circulation and the levels of chemicals, enzymes, proteins, and organic waste products that are normally found in the blood.
