Understanding the Red Blood Cell (RBC) Count
Jul 22, · The red blood cell (RBC) count is used to measure the number of oxygen-carrying blood cells in a volume of blood. It is one of the key measures we use to determine how much oxygen is being transported to cells of the body. An abnormal RBC count is often the first sign of an illness that may either be undiagnosed or without nicedatingusa.comted Reading Time: 5 mins. Red blood cells (RBCs), also called erythrocytes, are cells that circulate in the blood and carry oxygen throughout the body. The RBC count totals the number of red blood cells that are present in your sample of blood.

The red blood cell RBC count is used to measure the number of oxygen-carrying blood cells in a volume of blood. It is one of the key measures we use to determine how much oxygen is being transported to cells of the body. An abnormal RBC count is often the first sign of an illness that may either be undiagnosed or without symptoms.
At other times, the test can point the doctor in the direction of a diagnosis if there are symptoms, such as shortness of breath or fatigue, which cannot be readily explained. Typically speaking, an RBC count is less useful on its own to diagnose a medical condition. Instead, it is most often performed as part of a more comprehensive test called a complete blood cell CBC count which measures the composition cells in a blood sample.
Based on the composition of blood cells, doctors can better know where to focus their investigation and which areas they can probably avoid. This is especially true for cancer and cancer chemotherapy, both of which can have a detrimental cause-and-effect impact on blood counts. An RBC count is the number of red blood cell per a particular volume of blood. It may be reported in millions of cells per microliter mcL of blood or in millions of cells per liter L of blood.
The "normal" range can sometimes vary by population. Many reference values will be far higher in high-altitude cities like Denver and far lower in low-altitude areas like the Gulf Coast. As such, the ranges cannot be considered hard-and-fast values but rather, as the name suggests, a reference point. When the RBC count is higher or lower than the reference range, it alerts the physician that there could be an underlying condition. The other values from the CBC will be considered, as well as other diagnostic tests.
A high RBC count tells us that there has been an increase in oxygen-carrying cells in blood. A low RBC count indicates a decrease in oxygen-carrying cells in the blood, otherwise known as anemia.
Treatment of an abnormal RBC count is typically focused on treating the underlying condition, whether it be an infection, injury, cancer, or a genetic disorder. If, on the other hand, the cause is related to a nutritional deficiency, medication use, or a chronic condition, there may be things you can do to not only improve your blood count but your overall health, as well.

Here are 2 of the most common types of blood tests and what they can tell the doctor about your health: the complete blood count CBC and the chemistry panel. Some people find it helps to ask for a copy of their lab results and have a member of their cancer care team go over the numbers with them. By getting a copy, you can also see what the normal ranges are for the lab that tested your blood and where your numbers fall within that range.
Blood is made up of water, proteins, nutrients, and living cells. A CBC tells your cancer care team about the cells in your blood. It measures 3 basic types of blood cells:. Each of these cells has a special purpose.
And each can be harmed by cancer and cancer treatments. RBCs carry oxygen to and carbon dioxide away from the cells in your body. The CBC measures red blood cells in many ways, but the simplest measure is either.
Platelets help control bleeding. You may bruise or bleed easily when your platelet levels are low. The risk of bleeding goes up when platelet levels drop below 20, WBCs fight infection. There are many types of white blood cells and each fights infection in a special way. The number doctors look at is called your absolute neutrophil count ANC. A healthy person has an ANC between 2, and 6, Another type of blood test looks at blood chemistry.
Chemistry panels may also be called by other names, such as metabolic profile or blood chemistry profile. One blood sample can be used to measure many things like:. Certain blood chemistry tests can show how well your organs are working. For instance, liver function studies tell your doctor how well your liver is working. Other tests look at how well your kidneys are working.
The chemistry panel may also show other problems with body function. Your blood chemistry balance can also be changed by dehydration not enough fluid in the body , which may be caused by nausea , vomiting, or diarrhea. If the tests show that certain electrolytes are too low, your doctor may decide to replace them.
If the tests show you are dehydrated, you may be given intravenous IV fluids. Each lab has its own range for what it considers normal values for complete blood counts and chemistry panel results. Normal ranges for some tests also vary by age and gender.
As a rule, the normal ranges are printed on the lab report, next to your test results. For instance, a WBC result may be shown as 6.
RBCs are often shown as multiples of a million, sometimes abbreviated as M. Grams is shown by the letter g, and dL means deciliter. Results that are high or low might have the letter H or L after the number, or may be printed to the side or in a different column to call attention to the abnormal result. Again, getting a copy of your lab results lets you compare your numbers to the normal ranges and makes it easier to ask questions about the results and what they mean.
