Feeling sluggish? Anemia could be to blame.  

Anemia is a condition caused by a lack of healthy red blood cells, or low hemoglobin, in the blood. Red blood cells contain hemoglobin, which is responsible for carrying oxygen throughout the body; when those levels are low, the decreased levels of oxygen can cause symptoms such as fatigue, dizziness, and headaches. There are many types of anemia, each with their own cause; iron-deficiency anemia is the most common.

A CBC (complete blood count) with Differential measures (among other things) the red blood cells in your blood and can be used to detect anemia. Iron, B-12, and folate are also measured since mineral and vitamin deficiencies are common causes of anemia.


Fast for 12 hours (no food or drink, except water).

What's Included

Red Blood Count: Measures the number of red blood cells (erythrocytes). Red blood cells contain hemoglobin, a protein that carries oxygen throughout the body.
White Blood Count:

Detects the number of white blood cells (leukocytes) in the body, cells that fight off infections and foreign agents that may infect the body.


Measures the amount of hemoglobin in the blood, the oxygen-carrying protein in red blood cells.


Measures the proportion of red blood cells to the fluid component (or plasma) in your blood.

Platelet Count:

Measures the number of platelets in the blood, the cell components essential for blood clotting.


Measures the amount of ferritin in the blood, a red-blood-cell protein that stores iron in your cells.


Measures the level of iron, an essential mineral that is an important component of hemoglobin that serves to carry oxygen throughout the body, so that the body can produce energy.

Total Iron Binding Capacity:

Measures the blood’s capacity to bind iron with transferrin, a protein that combines with ferritin to deliver iron to new red blood cells.

Vitamin B12:

Measures the amount of B-12, a water-soluble vitamin that plays a vital role in the health of nerves and red blood cells.

Folate (Folic Acid):

The B vitamin that plays a vital role in making DNA, the genetic material in cells. Folic acid is a synthesized version of folate found in processed foods and supplements. A folate deficiency can lead to health complications, especially in pregnant women.

Reticulocyte Count:

Measures reticulocytes (immature blood cells) to determine if your bone marrow is producing an adequate amount of red blood cells.
