Hemoglobin is an essential protein in red blood cells that transports oxygen throughout our bodies. Maintaining normal hemoglobin levels is crucial to the proper functioning of our bodies, as oxygen is essential for the functioning of our cells.
Normal values for hemoglobin can vary, but are usually between 8.5 mmol/L and 10.9 mmol/L, depending on the laboratory. Healthy hemoglobin levels ensure that your body receives adequate oxygen.
What is Hemoglobin?
Hemoglobin is a protein in our red blood cells that binds and transports oxygen throughout our bodies. This process is vital because oxygen is essential for the functioning of all our body cells. When hemoglobin levels stay within a certain normal range, our body functions optimally. If it is too low, you will experience symptoms such as fatigue.
Hemoglobin Normal Value
The normal value for hemoglobin can vary depending on the laboratory and the units used. At many laboratories, hemoglobin levels are measured in millimoles per liter (mmol/L). For example, at Blood Value Testing, a normal hemoglobin level is used between 8.5 mmol/L and 10.9 mmol/L. This range indicates that your blood can carry enough oxygen to keep your body in peak condition.
What The Complete Blood Picture Shows.
The blood count, also known as hematological profile, contains several components that provide crucial information about your overall health. Here are some important aspects assessed alongside hemoglobin in the blood count:
Hematocrit (Ht): This indicates what proportion of your blood is made up of red blood cells. A normal hematocrit level is usually between 38.3% and 48.6%.
Red Blood Cell Count (RBC): This measures the number of red blood cells in a given amount of blood. A healthy range is between 4.5 million and 6.0 million cells per microliter.
White Blood Cell Count (WBC): This measures the number of white blood cells in your blood. Normally, this number is between 4,000 and 11,000 cells per microliter.
Platelet count (PLT): This indicates the number of platelets, important for clotting and wound healing. The normal value is usually between 150,000 and 450,000 platelets per microliter.
What If Your Blood Count Is Outside of Normal?
Abnormalities in your blood count can indicate various health problems. For example, low hemoglobin levels may indicate anemia, while high levels indicate dehydration or other diseases.
A comprehensive assessment of your blood count can help determine the cause of these abnormalities and establish an appropriate treatment plan. This may include changes in your diet, lifestyle, medication or other interventions.
Blood count: More than just Hemoglobin and Hematocrit
A complete blood count (blood count) is one of the most commonly performed laboratory tests and provides important insights into an individual's health. People are often familiar with terms such as hemoglobin and hematocrit, which are associated with anemia. However, it is critical to understand that the blood count includes much more than just hemoglobin and hematocrit.
This test analyzes not only the amount of hemoglobin in your blood, but also other important blood components, such as red and white blood cells and platelets. As a result, it can support the diagnosis and monitoring of various health conditions.
Red Blood Cells (Erythrocytes): Hemoglobin Transporters.
Red blood cells, also called erythrocytes, are responsible for transporting oxygen in the blood. Hemoglobin, a protein in red blood cells, binds to oxygen in the lungs and carries it throughout the body. When your hemoglobin levels are too low, it can indicate anemia, which can result in symptoms such as fatigue and weakness.
The blood count contains information about the quantity and size of red blood cells, which is essential for diagnosing anemia and related disorders.
White Blood Cells (Leukocytes): Body Defenders
White blood cells, also called leukocytes, play a crucial role in the immune system and protect your body from infections. The blood count measures the number and types of white blood cells, such as neutrophils, lymphocytes, monocytes, eosinophils and basophils. This information can help identify infections, allergies or even more serious conditions such as leukemia.
Platelets (Thrombocytes): Blood Coagulation
Platelets, or thrombocytes, are involved in blood clotting. A blood count analyzes the exact number of platelets in your blood. Too many platelets can lead to an increased risk of blood clots, while too few can easily lead to bleeding.
An excessive platelet count can occur with infections, iron deficiency, and after removal of the spleen. In some rare bone marrow disorders, this can involve both an increased risk of bleeding and thrombosis.
An insufficient platelet count can occur due to viral infections, impaired blood formation, vitamin B12 deficiency or damage to the bone marrow.
Deviant Values and Meaning
A blood count must be viewed in context. If one of the blood components deviates from the norm, it does not necessarily mean anything serious. Deviating values are often indicated by an up arrow (↑) for a high value and/or a down arrow (↓) for a low value.
However, a blood test is a snapshot, and sometimes it is advisable to repeat tests after a month if certain values need improvement.
How Is Blood Taken?
Blood is drawn by venipuncture, using a precise vacuum system to maintain a proper ratio of blood to anticoagulant. It is essential that the puncture site be disinfected, usually in the elbow crease. A tourniquet is used to visualize the veins, after which the needle is inserted. Blood is then collected in tubes for analysis.
The complete blood count is a valuable tool for physicians in diagnosing and monitoring health problems. It provides insight into the health of various blood components, allowing timely identification and treatment of abnormalities and conditions. Thus, in addition to hemoglobin and hematocrit, a blood count helps capture a wider range of health information and contributes to the well-being of individuals.
