Additional blood tests, which can provide some screening indicators for celiac or Crohn’s disease.This substance makes it possible for some ulcers to show up on the X-ray of your stomach and small intestine. X-rays of your upper GI, which involves drinking a thick liquid containing barium.Also, a biopsy performed during this procedure tests most reliably for celiac disease. An endoscopy, during which a lighted camera is moved through the upper part of your gastrointestinal (GI) tract.Your doctor may order diagnostic tests for other conditions, including: The easiest to detect is abnormally long, frequent, or heavy menstrual cycles, as women can self-report this. If blood loss is thought to be the cause of your low MCHC score, your doctor will look for the source of the blood loss. All of this can be done from the same blood draw used for your CBC, and these two tests can help your doctor determine the cause of the anemia. Your doctor may check your iron levels and iron-binding capacity, which measures whether your body absorbs iron the way it’s supposed to. This can help them create a course of treatment. Through the results of the tests they order, your doctor should be able to determine exactly what type of anemia you have, making it easier to find the underlying cause. A CBC measures whether you have normal ranges of red and white blood cells. These tests may be included in a complete blood count (CBC). a mean corpuscular volume (MCV) test, which measures the average volume of your red blood cells.a blood test that will examine your MCHC levels.Polycythemia (also known as polycythaemia or polyglobulia) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. To assess true red cell mass, independent radionuclide evaluation of the red cells and plasma (by 51Cr and 131I respectively) must be performed.Ĭopyright © 1990, Butterworth Publishers, a division of Reed Publishing.If your doctor suspects that you have a low MCHC, they may order several blood tests, including: A high hematocrit with a high RBC count and high hemoglobin indicates polycythemia. If a patient is severely dehydrated, the hemoglobin and hematocrit will appear higher than if the patient were normovolemic if the patient is fluid overloaded, they will be lower than their actual level. When so assayed, it is subject to the vagaries inherent in obtaining an accurate measurement of the MCV (see Chapter 152).īoth the hemoglobin and the hematocrit are based on whole blood and are therefore dependent on plasma volume. Automated cell counters calculate the hematocrit by multiplying the red cell number (in millions/mm 3) by the mean cell volume (MCV, in femtoliters). This value can be determined directly by microhematocrit centrifugation or calculated indirectly. The normal hematocrit for men is 40 to 54% for women it is 36 to 48%.
The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). An erythrocytosis is the consequence of too many red cells this results in hemoglobin levels above normal.
When the hemoglobin level is low, the patient has anemia. The normal Hb level for males is 14 to 18 g/dl that for females is 12 to 16 g/dl.
The amount of hemoglobin in whole blood is expressed in grams per deciliter (g/dl). To ensure adequate tissue oxygenation, a sufficient hemoglobin level must be maintained. As I discuss in my link on Testosterone and the Kidneys, this has to do with the fact that testosterone ramps up red blood cell production. Hemoglobin (Hb) is the protein contained in red blood cells that is responsible for delivery of oxygen to the tissues. Ways to Lower Hemoglobin Some men on HRT (testosterone therapy) find themselves with elevated hemoglobin (or hematocrit/red blood cell counts).
