Hemoglobin found in RBC carries oxygen to body tissues, normally found in our blood. This blood test measures the number of red blood cells in our blood. The reason behind the decreased number of red blood cells in our body can be due to certain types of cancer, chronic inflammatory disease, loss of blood, or because of chemotherapy. On the other hand, the number of red blood cells can increase due to several reasons such as anxiety, stress and dehydration. The Red blood cells testing is carried out as a part of full blood count testing.
