PreludeDX Reaches New Milestones for DCIS Patients and DCISionRT Testing

Hemoglobin is a vital protein found in red blood cells that plays a crucial role in transporting oxygen throughout the body. When you undergo a hemoglobin test, your healthcare provider measures the amount of this protein in your blood to assess your overall health and detect various medical conditions. This test is commonly included in a complete blood count, which is one of the most frequently ordered laboratory tests. Normal hemoglobin levels vary by age and gender, with adult men typically having levels between 13.5 to 17.5 grams per deciliter and adult women having levels between 12.0 to 15.5 grams per deciliter.

Low hemoglobin levels, known as anemia, can result from various causes including iron deficiency, vitamin B12 or folate deficiency, chronic diseases, blood loss, or bone marrow problems. When hemoglobin is low, your body's tissues and organs may not receive adequate oxygen, leading to symptoms such as fatigue, weakness, pale skin, shortness of breath, dizziness, and cold hands and feet. Anemia can range from mild to severe, and identifying the underlying cause is essential for proper treatment. Your doctor may order additional tests to determine why your hemoglobin is low and develop an appropriate treatment plan.

High hemoglobin levels are less common but can also indicate health problems. Elevated hemoglobin may occur in people living at high altitudes, smokers, or those with certain medical conditions such as polycythemia vera, lung disease, heart disease, or dehydration. When hemoglobin is too high, the blood becomes thicker, which can increase the risk of blood clots, stroke, or heart attack. Symptoms of high hemoglobin might include headaches, dizziness, itching, and an enlarged spleen.

The hemoglobin test is a simple blood test that requires only a small sample drawn from a vein in your arm. No special preparation is usually needed, though you should inform your healthcare provider about any medications or supplements you are taking. Results are typically available within a day or two. If your hemoglobin levels are abnormal, your doctor will consider your symptoms, medical history, and other test results to determine the cause and recommend appropriate treatment, which might include dietary changes, supplements, medications, or further diagnostic testing.
