Hemoglobin, a compound present in red bl cells, gives b its red color.
The molecular structure of hemoglobin allows hemoglobin to bind with oxygen (within the red blood cell). Circulation of red cells then serves to transport oxygen throughout the body. The hemoglobin test, a measurement of hemoglobin levels in the blood, is another way of determining whether red cells are normal. Most patients with low hemoglobin also have: Low RBC Low hematocrit Normal ranges for hemoglobin are:Adult females: 12 to 16 grams of hemoglobin per deciliter (dL, a tenth ofa liter) of blood Adults males: 14 to 18 g/dL Low hemoglobin, like low RBC or low hematocrit, is an indicator of anemia. What is a white blood cell count? White blood cells are cells of the immune system, responsible for protecting the body from infection and malignancy. A white blood cell count (WBC) is ordered to check whether the number of white cells in the blood is abnormally high or abnormally low.
Patients with a low WBC are at increased risk for infectious disease.Normal WBC count is 4. 8 to 10. 8 thousand WBC per microliter (uL) of blood. Low WBC may indicate: Overwhelming infection AIDS Certain cancers/cancer treatment High WBC may indicate: Infection Leukemia What is a differential blood count? There are 5 different types of white blood cell: Neutrophils Lymphocytes Monocytes Eosinophils Basophils In a differential blood count (DifO, the numbers of different types of white blood cell are measured, to aid in a variety of diagnoses.
Normal ranges for a Diff are:Neutrophils: 3150 to 6200 neutrophils per microliter (uL) of blood Lymphocytes: 1500 to 3000/LlL Monocytes: 300 to 500/uL Eosinophils: 50 to 250/uL Basophils: 15 to 50/uL High neutrophil count can indicate: Certain types of cancer Arthritis Physical stress to the body, such as following: Surgery Trauma Heart attack Low lymphocyte count can be a symptom of AIDS. High monocyte count can indicate infection, often bacterial infection. High eosinophil count can indicate: Allergies Certain skin diseases Parasitic infectionImmature white blood cells of any type can indicate: Bacterial infection What is a platelet count? Platelets are cell fragments essential for the process of blood clotting. A platelet count may be performed if a patient: Is prone to bruising Is about to undergo surgery A normal platelet count is 150 to 450 thousand platelets per microliter of blood.
Low platelet counts (thrombocytopenia) may occur as a result of: Cancer treatment Certain leukemias Certain other types of cancer Immune thrombocytopenic purpura I
