Overview What is a hematocrit test? A hematocrit test (Hct) is a simple blood test that measures the percentage of red blood cells in your blood. Red blood cells are important because they carry oxygen throughout your body. Test results showing low or high hematocrit levels may be signs of blood disorders or other medical conditions. When do healthcare providers order hematocrit tests? Hematocrits are parts of What’s the difference between a hematocrit and a hemoglobin test? A hematocrit is the percentage of red blood cells in your blood. Hemoglobin is part of your red blood cell. Hemoglobin helps your red blood cells carry oxygen throughout your body. Hemoglobin also gives your red blood cells their color. A Test Details How do healthcare providers obtain blood for hematocrit levels? Blood tests to check hematocrit levels are simple, safe procedures with very few complications. Sometimes, providers obtain blood from a vein, using a needle to fill one or more sample tubes. Other times, providers use a needle prick to obtain a drop of blood. Here are blood test details: • Your provider looks for a vein from which to draw blood. They typically pick a vein on the inside surface of your elbow. • They place a tourniquet on your upper arm. Pressure from the tourniquet helps fill veins below the tourniquet, making it easier for your provider to see or feel your veins. • Your provider cleans the area around the vein selected for the blood draw. • Next, they insert a needle into yo...

Red blood cell distribution width (RDW) blood test measures the amount of red blood cell variation in volume and size. However, RDW is not used as an isolated parameter when interpreting a complete blood count (CBC). What is an RDW blood test? The red cell distribution width (RDW) blood test measures the amount of You need red blood cells to carry However, with certain diseases, you may still have a normal RDW. Normal This means that if on average your RBCs are small, but you also have a lot of very small cells, your RDW will be elevated. Similarly, if on average your RBCs are large, but you also have a lot of very large cells, your RDW will be elevated. For this reason, RDW is not used as an isolated parameter when interpreting a complete blood count (CBC). Rather, it provides shades of meaning in the context of the hemoglobin (hgb) and mean corpuscular value (MCV). High RDW values may mean you have a nutrient deficiency, The RDW test is used to help diagnose types of • • • • • This test is commonly performed as a part of a The CBC determines the types and These tests help to determine your overall health status and, in some cases, diagnose infection or other diseases.

Regular blood testing is one of the most important ways to keep track of your overall physical well-being. Getting tested at routine intervals can allow you to see the way your body changes over time and empower you to make informed decisions about your health. What does a blood test show? Some blood tests can help your doctor determine how different organs in your body are working. Examples of organs whose malfunctions can be visible in a blood test Your doctor can also use blood tests to search for markers of diseases and health conditions such as: • diabetes • HIV • anemia • cancer • coronary heart disease Even if a person does not have heart disease, a blood test can show whether they may be at risk of developing the condition. Other blood tests can indicate whether the medications you’re taking are working properly, or assess how well your blood is clotting. Let’s take a closer look at some common blood tests. 1. Complete blood count A routine complete blood count (CBC) checks for levels of 10 different components of every major cell in your blood: white blood cells, red blood cells, and platelets. Important components this test measures include red blood cell count, hemoglobin, and hematocrit. Here’s the Component Normal range red blood cells (cells responsible for carrying oxygen throughout the body) male: 4.3–5.9 million/mm 3; female: 3.5–5.5 million/mm 3 white blood cells (immune system cells in the blood) 4,500–11,000/mm 3 platelets (the substances that control t...

Hemoglobin, sometimes abbreviated as Hgb, is a protein in red blood cells that carries iron. This iron holds oxygen, making hemoglobin an essential component of your blood. When your blood doesn’t contain enough hemoglobin, your cells don’t receive enough oxygen. Doctors determine your • age • gender • medical history Keep reading to learn more about what’s considered a normal, high, and low hemoglobin level. Sex Normal hemoglobin level (g/dL) Female 12 or higher Male 13 or higher Older adults also tend to have lower hemoglobin levels. This may be due to several factors, including: • lower iron levels due to chronic inflammation or poor nutrition • medication side effects • high rates of chronic diseases, such as kidney disease Children Infants tend to have High hemoglobin levels generally accompany high red blood cell counts. Remember, hemoglobin is found in red blood cells, so the higher your red blood cell count, the higher your hemoglobin level and vice versa. A high red blood cell count and hemoglobin level can indicate several things, including: • Congenital heart disease. This • Dehydration. Not having enough fluid can cause red blood cell counts to appear higher because there isn’t as much fluid to balance them. • Kidney tumors. Some kidney tumors stimulate your kidneys to make excess erythropoietin, a hormone that stimulates red blood cell production. • Lung disease. If your lungs aren’t working effectively, your body may try to produce more red blood cells to hel...

Hemoglobin is a protein in your red blood cells. Your red blood cells carry oxygen throughout your body. If you have a condition that affects your body’s ability to make red blood cells, your hemoglobin levels may drop. Low hemoglobin levels may be a symptom of several conditions, including different kinds of anemia and cancer. Overview What is low hemoglobin? Hemoglobin is a protein in your What happens when hemoglobin is low? If a disease or condition affects your body’s ability to produce red blood cells, your hemoglobin levels may drop. When your hemoglobin level is low, it means your body isn’t getting enough oxygen, making you feel very tired and weak. At what level is hemoglobin dangerously low? Normal hemoglobin levels are different for men and women. For men, a normal level ranges between 14.0 grams per deciliter (gm/dL) and 17.5 gm/dL. For women, a normal level ranges between 12.3 gm/dL and 15.3 gm/dL. A severe low hemoglobin level for men is 13.5 gm/dL or lower. For women, a severe low hemoglobin level is 12 gm/dL. What tests do healthcare providers use to diagnose low hemoglobin? Healthcare providers diagnose low hemoglobin by taking samples of your blood and measuring the amount of hemoglobin in it. This is a Possible Causes What causes hemoglobin levels to go low? Several factors affect hemoglobin levels: • Your body doesn’t make enough red blood cells. Your body produces red blood cells and white blood cells in your bone marrow. Sometimes, conditions and dis...

• Red blood cell count (RBC): • White blood cell count (WBC): There are many different types of white blood cells. • Platelet count: Platelets are responsible for forming clots (along with clotting factors in the blood) to stop bleeding. They are responsible for the scabs you see when you cut your skin. Interpreting Results There are many reasons for doctors to check a CBC. With cancer, a complete blood count (CBC) is often checked at the time of diagnosis, and to follow the levels of blood cells during treatment. Chemotherapy interferes with cell division in rapidly dividing cells such as cancer cells but also affects rapidly dividing cells in the bone marrow. Abnormal levels of cells in the blood during
