MCH Blood Test - MCH Blood Test, Reasons, Preparation, Procedure, Results
Blood tests are said to be very important as they tell a lot about a person’s health. A Complete Blood Count test may generally be conducted to determine the presence of any diseases or disorders in the body. This entails examining the different components of your blood that include white blood cell count, red blood cell count, a platelet count, along with mean corpuscular volume, the hemoglobin, hematocrit mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and also red cell distribution width. The red blood cell count plays a crucial role in determining the various types of anemia and the inability of the blood to carry enough oxygen.
MCH Blood Test Reasons
MCH blood test, known as Mean Corpuscular Hemoglobin is a test conducted to know the average weight of hemoglobin that is present inside a red blood cell. The main responsibility of hemoglobin is to carry oxygen to the blood. It is composed of a group of amino acids that contain iron atoms which gives the red color to hemoglobin. MCH, MCV and MCHC are three main red blood cell indices that help in measuring the average size and hemoglobin composition of the red blood cells. A low MCH indicates an iron deficiency whereas a high MCH results in too much hemoglobin present which causes insufficient supply of oxygen to the blood.
MCH Blood Test Preparation
There are no specific preparations that are required for the test unless the doctor specifies otherwise. You may be asked not to consume any fatty meals a few hours prior to taking the test.
MCH Blood Test Procedure
MCH is a blood test and is taken by removing blood from your vein which is then given for further testing. A sample of your blood can also be collected by pricking a sharp instrument, which is similar to a needle, on your finger tip and making it bleed. Normal MCH blood test results do not indicate any problems and therefore there is nothing to worry about. These normal results will have the mean corpuscular hemoglobin within the range of 27 to 33 picograms per cell. MCH blood test high indicates that there is a poor supply of oxygen to the blood where as MCH blood test low mean that hemoglobin is too little in the cells indicating a lack of iron. It is important that iron is maintained at a certain level as too much or too little iron can be dangerous to your body.
