Your Blood Count
The goal of cancer treatment – either chemotherapy or radiation therapy – is to interfere with the growth of cancer cells and ultimately destroy them. However, some of your body’s normal cells, the hair follicles, the blood cells and the cells lining in the mouth and gastrointestinal tract are sensitive to these treatments and may also be damaged. Treatments also affecting these cells cause symptoms known as “side effects”.
What To Do If You Have Concerns
Some treatments can slow or decrease the production of blood cells. That is why, during the course of your therapy, the doctor will take samples of your blood to closely watch your blood cell “count”.
If you are concerned about your blood count or wish to discuss a result with your doctor – please contact your healthcare provider.
What is Nadir?
Your chemotherapy treatment is expected to lower your blood count. This is called the nadir and usually occurs around day 7 to 14 following the last day of chemotherapy.
White Blood Counts
A white blood count with differential provides all the information about your white blood cells. White blood cells help protect the body by fighting bacteria, fungi or viruses that cause infections. Therefore, it is especially important to protect yourself against infection when your white cell count is low.
| Test | Average | Abnormal |
| WBC | 4.5 - 11.0 | 1.5 or below |
Red Blood Cells
One function of red blood cells is to carry oxygen to the tissues in your body. Hemoglobin and hematocrit are the tests used to evaluate red blood cells. While these measures are low, your body tissues do not get enough oxygen to do their work. This results in a condition called anemia.
| Test | Average | Abnormal |
| Hemoglobin | 12.0 - 16 | 8.0 or below |
| Hematocrit | 38 - 47 | None |
Platelets
A platelet count is the blood test that measures the number of platelets in your body. Platelets help your blood to clot, preventing excessive bleeding. If you are injured you may bleed or bruise more easily then usual if your platelet count is low.
| Test | Average | Abnormal |
| Platelet Count | 150 - 450 | 30 or below |
