What is a healthy CD4 count?
A normal CD4 count ranges from 500–1,200 cells/mm3 in adults and teens. In general, a normal CD4 count means that your immune system is not yet significantly affected by HIV infection. A low CD4 count indicates that your immune system has been affected by HIV and/or the disease is progressing.
How is CD4 calculated?
A CD4:CD8 ratio is calculated by dividing the number of CD4+ T cells by the number of CD8+ T cells; this ratio is usually greater than 1 in immunocompetent individuals [4]. However, in HIV infection, the CD4:CD8 ratio is usually less than 1.
What does it mean when your blood count is low?
What is a low blood count? A low blood count means that you have fewer red or white blood cells or fewer platelets in your body than normal. A low blood count is diagnosed using a test called a full blood count, where your blood levels are compared with the population average.

The term “ANC,” which stands for “Absolute Neutrophil Count,” is the total number of neutrophils in your child’s white blood cell count.
What is the normal white blood cell count?
White blood cells fight infection. A normal white blood cell count is between 5,000 and 10,000 cells. A white blood cell count below 1,000 cells increases the risk of infection.
If your white blood cell count is higher than normal, you may have an infection or inflammation. Or, it could indicate that you have an immune system disorder or a bone marrow disease. A high white blood cell count can also be a reaction to medication.
How are white blood cells counted without differential?
CBC without differential counts the total number of white blood cells. CBC with differential. There are five kinds of white blood cells. The differential looks at how many of each kind of white blood cell you have. Hemoglobin tests measure hemoglobin, the protein in red blood cells that carries oxygen.
