A normal count ranges from 4,000 11,000/mm3 in a healthy adult. A high count may mean that your body is ighting an infection. Low counts may result from taking certain drugs (AZT or ganciclovir), minor viral infec­ tions, stress or more serious opportunistic infections such as tuberculosis, histoplasmosis or other infection.

Interpreting the CBC

A high RDW indicates a large variation in size of RBCs If the MCV is normal and the RDW is high, there is a mixture of large and small RBCs If the RDW is normal and the MCV is high, the RBCs are likely all macrocytic If the MCV and RDW are both normal, the RBCs are likely all about the same normal size MCV = normal RDW = normal MCV = normal

A neutrophil count of between 1-5 - 2.0 x 109/l whilst below the normal range is unlikely to be of any clinical significance.

cell is referred to as hypochromic. MCHC results that fall in the normal range indicate that the cell is normal in color or normochromic. However, the MCHC can also be normal when both the MCV and MCH are either low or high. It is less common to have an MCHC that is greater than normal because cells have a limited capacity and

Since the MCV is derived from the entire populations of RBC with a life span of about 120 days, it takes some time to be altered by an acquired anemia (such as state of iron deficiency for example). *XB monitors instrument performance by tracking the MCV, MCH, and MCHC parameters of all patient samples.

The diluted count should match within 0.10 x 10 6/uL of the original count. For example, if the original RBC is 5 x 10 6/uL, the count on your dilution should be between 4.9 and 5.1 x 10 6 /uL. Take the original RBC and HCT results and the corrected Hgb and correct the mean corpuscular hemoglobin (MCH) and MCHC using the following formulas:

the mean corpuscular volume (MCV) is significantly larger than normal. However, an increased MCV does not automatically lead to a diag-nosis of macrocytosis. For example, cells with an increased MCV can be found in patients with folic acid or vitamin B12 deficiency (as in the case of megaloblastic anemia) or with chronic liver disease

The mean corpuscular volume (MCV) is a measure of the average size or volume of the individual red blood cells. The MCV can provide valuable clues to the possible causes of anemia. Failure to produce adequate hemoglobin results in smaller than normal cells and a low MCV. Iron deficiency anemia is an example of a condition with a lower than

A dissociation between MCV and MCH was recently described (13): high MCV and low MCH. This was the case of macrocytic hypochro-mic anemia, indicating the coexistence of both macrocytosis due to cobalamin/folate deficiency and

Mean corpuscular volume (MCV) is the average volume of a red blood cell and is calculated by dividing the hematocrit (Hct) by the concentration of red blood cell count. A normal range for MCV is between 80 and 96 femtoliters per cell. A low MCV indicates that the red blood cells are small, or microcytic.

Platelet Count Platelets are blood products critical for normal clotting. Abnormal values (either high or low) may be clues to an underlying blood disorder.

white blood cell count is simply the number of white blood cells in your blood. It is often reported in thousands. High WBC can be a sign of infection. WBC is also increased in certain types of leukemia. Low white counts can be a sign of bone marrow diseases or an enlarged spleen. Low WBC is also found in HIV infection in some cases.

The MCH value tends to be proportional to MCV. The size of a cell is largely determined by the haemoglobin content. Cells that have a normal MCH are referred to as normochromic whereas those with low values are termed hypochromic.

The mean corpuscular volume is the aver-age volume of red blood cells. Providers use it to classify anemia as either microcytic, normo-cytic, or macrocytic, each with its own differ-ential diagnosis. The differential white blood cell count provides absolute counts and relative percent-ages of each type of leukocyte. For example,
