what does it mean when you don't have white blood cells?
316276
If you had no white cells, you would get lots of very serious infections. White blood cells can find germs that enter your body and destroy them, which keeps them from making you sick. Some white blood cells make antibodies, which are special molecules that can stick to germs and make them harmless.

A low RBC count may indicate anaemia, bleeding, kidney disease, bone marrow failure (for instance, from radiation or a tumour), malnutrition, or other causes. A low count may also indicate nutritional deficiencies of iron, folate and vitamin B12.

A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection. A reaction to a drug that increases white blood cell production. A disease of bone marrow, causing abnormally high production of white blood cells.

A low WBC count can be serious because it increases your risk of developing a potentially life-threatening infection. Seek prompt medical care if you have a low WBC count and have signs of an infection, such as a fever, swollen lymph nodes, sore throat, or skin lesions.

The white blood cell count (WBC) is used as part of a full complete blood count (CBC) to: Screen for a wide range of diseases and conditions. Help diagnose an infection or inflammatory process or other diseases that affect the number of WBCs, such as allergies, leukemia or immune disorders, to name a few.

Infection. With a low white blood cell count and, in particular, a low level of neutrophils (neutropenia), a type of white blood cell that fights infection, you're at higher risk of developing an infection. And if you develop an infection when you have a low white blood cell count, your body can't protect itself.

Definition. Neutropenia (noo-troe-PEE-nee-uh) occurs when you have too few neutrophils, a type of white blood cells. While all white blood cells help your body fight infections, neutrophils are important for fighting certain infections, especially those caused by bacteria.
749987
White blood cells work to destroy any foreign virus, fungus, or bacteria that enter your body. When you get sick, your white blood cell count is higher than normal. This is because your body is releasing more of these cells to fight the infection.
1373250
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.
1359096
A high white blood cell count alone doesn't cause any symptoms. The symptoms you feel may come from the medical problem that your white blood cells are fighting. For example, if you have pneumonia, you may have a fever and trouble breathing.
448052
A low hemoglobin count can be associated with a disease or condition that causes your body to have too few red blood cells. This can occur if: Your body produces fewer red blood cells than usual. Your body destroys red blood cells faster than they can be produced.

What if you had no white blood cells? If you had no white cells, you would get lots of very serious infections. White blood cells can find germs that enter your body and destroy them, which keeps them from making you sick.

If you have a low white blood cell count, your doctor can prescribe medicines to help stimulate your immune system after each round of chemotherapy. Your doctor also may decide to stop your chemotherapy treatment for a little while so your body can recover and make more white blood cells.

A high WBC count likely indicates that an infection is present somewhere in the body, while a low number might indicate that an infection or disease—such as HIV or cancer—has slowed the bone marrow's ability to produce new WBCs. Red blood cells (erythrocytes) are responsible for delivering oxygen throughout the body.
1053649
A low red blood cell count is called anemia. If you have a low red blood cell count, you may: Feel a little tired or very tired. Feel less alert or have trouble concentrating.
356951
White cell (leucocyte) count A number of viral infections can cause a temporary reduction in the white cell count. Abnormally high levels of white blood cells may indicate infection, tissue damage, leukaemia, or inflammatory diseases. The normal white cell count for adults is 4.0-11.0 x 109/L.
523897
Microscopic exam White blood cells (leukocytes) may be a sign of an infection. Red blood cells (erythrocytes) may be a sign of kidney disease, a blood disorder or another underlying medical condition, such as bladder cancer. Bacteria or yeasts may indicate an infection.
