There are about a thousand times as many red blood cells as white cells.

Consider that the red blood cells (or erythrocytes) in a mm3 (or microliter) of blood number about five million in an average man (a few less in a woman). The white blood cells (or leukocytes) number only 5-6 thousand per mm3 so the ratio is about a thousand fold.

Helper T cells are a type of white blood cell that play a crucial role in the immune response by coordinating and regulating the activities of other immune cells. They help activate B cells to produce antibodies and assist cytotoxic T cells in killing infected cells. Helper T cells are essential for a properly functioning immune system.

Monocytes Absolute refers to the number of monocytes in a blood sample. Monocytes are a type of white blood cell that helps fight infections. High levels of monocytes may indicate an ongoing infection, autoimmune disorder, or certain types of cancer. Further testing is usually needed to determine the underlying cause of elevated monocytes.

Based on these percentages alone, it is not possible to determine if someone has HIV/AIDS. Diagnosis of HIV/AIDS requires specific laboratory tests to detect the presence of the virus. It is recommended to consult a healthcare professional for further evaluation and testing.
