The normal range for WBC is 5 to 10 K/uL.
A WBC count is a test that measures the number of white blood cells in your body. This test is often included with a complete blood count (CBC). Your blood contains a percentage of each type of white blood cell. Sometimes, however, your white blood cell count can fall or rise out of the healthy range. If your white blood cell count remains high or low, this can indicate that your condition has worsened and your doctor may adjust your treatment. If your WBC count shows a normal range, this indicates that the treatment is working. 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. A CBC helps your doctor check any symptoms, such as weakness, fatigue, or bruising, you may have. Normal values for the complete blood count (CBC) tests depend on age, sex, how high above sea level you live, and the type of blood sample. Your doctor may use all the CBC values to check for a condition Normal platelet counts are in the range of 150,000 to 400,000 per microliter (or 150 - 400 x 109 per liter), but the normal rangefor the platelet count varies slightly among different laboratories.  1 WBC (white blood cell) count signifies the number of white blood cells in the blood and usually ranges between 4,300 and 10,800 cells per cubic millimeter (cmm). 1 Red cell distribution width (RDW) measures the variability in the red blood cells' size and shape and usually ranges between 11 to 15. 2  Platelet count measures the number of platelets in a volume of blood and usually ranges between 150,000 to 400,000 per cmm. Red blood cell count, hemoglobin and hematocrit. 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. A complete blood count is typically not a definitive diagnostic test. Depending on the reason your doctor recommended this test, results outside the normal range may or may not require follow-up. Each time you have a CBC, you’ll find numbers for each part in your results. Keep in mind that normal ranges may be slightly different for men and women. The 5 parts of a CBC are:  White blood cell (WBC) count White blood cells help your body fight off infections. The normal range for WBC is 5 to 10 K/uL. Your CBC will also measure what’s called the ANC (absolute neutrophil count) That’s the specific number of white blood cells in your blood that fight infection. The normal range for HGB is 12 to 17.4 g/dL. Patient Education 2 Understanding your complete blood count  Hematocrit (HCT) value The hematocrit value measures how much of your total blood count is made up of red blood cells. The normal range for HCT is 36 to 52% An average normal range for white blood cells is between 4,500 and 10,000 mcl. Abnormal test results are classified by numbers that are higher or lower than this range. It’s important to note that age can also affect the number of white blood cells, with infants having a higher count than adults. If your white blood cell count remains high or low, this can indicate that your condition has worsened and your doctor may adjust your treatment. If your WBC count shows a normal range, this indicates that the treatment is working. 1 Platelet count measures the number of platelets in a volume of blood and usually ranges between 150,000 to 400,000 per cmm. 2  Mean platelet volume (MPV) measures the average size of platelets in a volume of blood. 3  The normal range is between 6 to 12 femtoliters (a very small fraction of a liter). 1 Red cell distribution width (RDW) measures the variability in the red blood cells' size and shape and usually ranges between 11 to 15. 2
