Mean corpuscular hemoglobin (HCM) in a blood test refers to the average amount of hemoglobin in a person’s red blood cells. Hemoglobin – it is a protein that carries oxygen throughout the human body. HCM is one of the standard measurements in a complete blood test.
Determination of haemoglobin
Before we delve into the details of HCM levels in blood test results, it’s important to understand that it measures the average amount of hemoglobin in a person’s red blood cells, which are also known as red blood cells. Human blood is made up of red blood cells, white blood cells, and platelets. Of these, red blood cells are responsible for transporting oxygen and carbon dioxide throughout the body.
Erythrocytes they contain a protein called hemoglobin, which contains iron. These red blood cells carry oxygen to tissues throughout the human body and remove waste (in this case, carbon dioxide) from the tissues, which then leave the body on exhaling through the lungs. When combined with oxygen, hemoglobin gives the blood a red color.
How Hemoglobin Is Measured
A person’s annual exam with their family doctor, or when their doctor needs more information to help with a possible diagnosis, usually includes a blood test known as complete blood test (CBC). Technically a series of multiple tests, the idea of CBC is to obtain information about three types of blood cells of the patient: red blood cells, white blood cells and platelets.
CBC requires a small sample of blood, usually taken from a vein in a person’s arm with a needle. Although tolerable for many people, others experience physical and/or mental discomfort when it comes to needles or blood collection. Once this part is complete, the lab experts will test the blood and provide a report to the doctor who ordered the test.
When blood test results are ready, they provide detailed information about how many cells are in the blood and the physical characteristics of the cells, such as Size, shape, and content. AT THE CBC mean measurement of corpuscular hemoglobin (HCM) – this is the average amount of hemoglobin in a red blood cell.
The value of MCH in a person is usually the same as his mean corpuscular volume (MCV), which measures the actual size of red blood cells. For this reason, your doctor may decide to skip this part of the CBC. But that doesn’t mean HCM levels are useless: they also provide important information about whether anemia is hyper, hiccups, or normal.
Understanding MCH in test results
If the doctor uses HCM levels to help with the diagnosis or simply to learn more about the patient’s health status, he or she first checks to see if he or she is in the normal range of 27 to 31 picograms/cell. There are specific symptoms and conditions associated with HCM levels that are below and above normal. Here’s an overview of what these levels can say about human health.
Low HCM levels
The presence of HCM levels below 27 picograms/cell is most often associated with anemia. But in addition to anemia, it can also be a sign of conditions like:
- Iron deficiency (most often caused by blood loss)
- Deficiency of other nutrients such as vitamin B12 or folic acid
- Internal or external blood loss as a result of surgery, trauma, menstrual bleeding, or bleeding from the gastrointestinal tract
- Thalassemia (a common inherited blood disorder caused by genetic mutations in hemoglobin genes)
- Kidney disease
- Autoimmune diseases
- Liver disease
People with low HCM may experience symptoms including:
- Pale skin (paleness)
- Cold hands and feet
High levels of HCM
The presence of HCM levels above 31 picograms / cell is most often associated with the following States:
- Polycythemia fe (a rare blood disorder usually caused by a genetic mutation in which the bone marrow produces too many red blood cells)
- Congenital heart defects
- Some types of kidney diseases, including kidney cancer
- Lung diseases, including chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis
People with high HCM levels may experience symptoms including:
- Blurred or double vision
- Blood clot
Treatment options for abnormal HCM levels
If a patient’s HCM levels are above or below normal, it will result in a discussion with your doctor about what it means for your overall health, including possible treatment options if needed.
There are many reasons why HCM levels may be out of the normal range, and that doesn’t necessarily mean a person has a serious illness or even cause for concern.
A Few Words From Get Meds Info
While doctors can learn a lot about a person’s health with CBC, including HCM levels, this is just one aspect of making an accurate diagnosis. Other factors, including family history, specific symptoms, and lifestyle, also provide important information about a person’s overall health and the likelihood of a particular disease.
This requires open and honest conversations between healthcare providers and patients to get a more complete picture of what a particular blood test result might be causing, including HCM levels.
