    What is a Haemoglobin Test?

    Haemoglobin test measures the amount of haemoglobin, the protein in red blood cells responsible for transporting oxygen from the lungs to the body’s tissues and organs. Adequate haemoglobin levels are crucial for ensuring that tissues receive the oxygen necessary for their function.

    Abnormally low or high haemoglobin levels can disrupt the body's oxygen supply, potentially causing health problems. Physicians often recommend a Haemoglobin test if you exhibit symptoms of abnormal haemoglobin levels. This test is useful for diagnosing blood disorders like anaemia, identifying the underlying causes, assessing severity, and monitoring treatment efficacy.

    With Delhi’s busy lifestyle, prioritizing health can be challenging. If your doctor advises a Haemoglobin test, book your appointment in Delhi today.

    Haemoglobin Test Parameters

    The Haemoglobin test specifically measures the concentration of haemoglobin in the blood.

    Haemoglobin is composed of a protein called globin and a compound known as haem, which contains iron and a pigment called porphyrin. Porphyrin gives blood its red colour, and the iron in haemoglobin allows it to bind with oxygen, facilitating oxygen transport from the lungs to the rest of the body. This oxygen is essential for cellular energy production and overall health. A deficiency in haemoglobin or a low red blood cell count can impair oxygen delivery, impacting energy and health. On the other hand, an excess of haemoglobin or too many red blood cells can thicken the blood, slowing its flow and potentially reducing oxygen supply to organs. Thus, a Hb test can help assess haemoglobin levels and guide appropriate action if needed.

    Haemoglobin Test Preparation

    Before scheduling a Haemoglobin test at home, consider the following prerequisites:

    Prerequisites for Haemoglobin Test

    Fasting is not required for the Hb test.

    Best Time to Get a Haemoglobin Test

    The Hb test can be performed at any time of the day.

    Who Should Get an Haemoglobin (Hb) Test

    An Hb test may be needed as part of routine blood work or if you have symptoms of low or high haemoglobin levels. It is also used for:

    • Diagnosing or evaluating conditions causing anaemia (low haemoglobin) or polycythaemia (high haemoglobin).

    • Assessing the severity of a condition.

    • Monitoring your haemoglobin response to treatment.

    Cautions Before Taking an Hemoglobin Test

    No special preparation is needed, but various factors can influence haemoglobin levels, such as:

    • Fluid Intake: High fluid intake can lower haemoglobin levels.

    • Exercise: Intense exercise can raise haemoglobin levels.

    • Medications: Some drugs (e.g., anabolic steroids, and antiretrovirals) can affect haemoglobin levels.

    • Altitude: Living at high altitudes can increase haemoglobin levels.

    • Pregnancy: Haemoglobin levels may be lower during pregnancy.

    Your doctor will guide you with any other specific prerequisites.

    Why Take a Haemoglobin Test?

    Your doctor might recommend a Haemoglobin test if you show symptoms of abnormal haemoglobin levels.

    Symptoms of Low Haemoglobin:

    • Pale skin

    • Cold hands and feet

    • Dizziness

    • Chest pain

    • Fatigue

    • Weakness

    • Headache

    • Shortness of breath

    Symptoms of High Haemoglobin:

    • Stroke

    • Heart attack

    • Easy bruising

    • Weight loss

    • Dizziness

    • Weakness

    • Excess sweating

    • Headaches

    • Blood clots

    • Blurred or double vision

    • Swelling of joints

    • Itching

    • Yellowing of eyes and skin

    Additionally, your doctor may use this test to track your response to treatments that adjust your red blood cell count. Other reasons for an Hb test include:

    • Having a diet that lacks essential nutrients like iron, vitamin B12, and folate.

    • Experiencing chronic infections.

    • A family history of blood disorders such as thalassaemia or sickle cell anaemia.

    • Blood loss during surgery or injury.

    Interpretation of Haemoglobin Levels

    Low Levels: Several factors can cause low haemoglobin levels, which may impact your body's ability to produce or sustain sufficient red blood cells. Common causes include:

    • Inadequate Red Blood Cell Production: This can result from various types of anaemia (such as pernicious or aplastic anaemia), cancers affecting the blood or bone marrow (like leukaemia, lymphoma, myelodysplastic syndrome, or multiple myeloma), chronic kidney disease, chemotherapy, and certain medications, including antiretroviral drugs.

    • Increased Red Blood Cell Destruction: Conditions like sickle cell anaemia, thalassaemia, and an enlarged spleen can shorten the red blood cell lifespan.

    • Blood Loss: Causes include injury, surgery, heavy menstrual periods, or internal bleeding.

    • Other Factors: Deficiencies in nutrients like iron, vitamin B12, or folate, and conditions that impair iron absorption, can hinder the production of healthy red blood cells.

    High Levels: High haemoglobin levels might point to a significant health issue and increase the risk of complications such as blood clots. Potential causes include:

    • Medical Conditions: Chronic obstructive pulmonary disease (COPD), congenital heart disease, polycythaemia vera, emphysema, pulmonary fibrosis, liver cancer, and kidney cancer.

    • Other Factors: High-altitude living, smoking, dehydration, carbon monoxide exposure, and the use of drugs like anabolic steroids can also elevate haemoglobin levels.

    Please remember that abnormal results don't necessarily indicate a health problem. Various factors, including diet, medications, menstrual cycles, and physical activity, can affect your haemoglobin levels. It’s best to discuss your results with your doctor for a proper interpretation.
