Haemoglobin, also known as Hgb or Hb, is a crucial protein that transports iron and is a major component of the red blood cells in the body. As this iron can store oxygen, transporting it from the lungs to other parts of the body, haemoglobin is a crucial component of blood. If the haemoglobin levels are low, it can indicate anaemia, and in the case of high levels, it can indicate the body needs an increased capacity to carry oxygen.

Overview of the Haemoglobin Estimation Test

An important component of red blood cells, haemoglobin is a protein that is responsible for carrying oxygen from the lungs to the body's organs and tissues.

The normal level of haemoglobin in females and males varies depending on their gender and other factors like age, medical history, etc. A higher-than or lower-than-normal haemoglobin level can cause symptoms like dizziness, weakness, exhaustion, etc., and more often than not is indicative of an underlying medical condition. For determining the amount of haemoglobin in the blood, a blood test for Hb estimation may be prescribed.

A Haemoglobin (Hb) estimation test is a blood test that measures the amount of haemoglobin in the blood. Haemoglobin is a vital protein in the red blood cells, primarily responsible for transporting oxygen from the lungs to the rest of the body. The haemoglobin lab test helps evaluate the oxygen-carrying capacity of the blood. The meaning of abnormal levels of haemoglobin in the blood test can be a diagnosis of conditions like anaemia, sickle cell anaemia, leukaemia, etc. So, a routine examination can help healthcare providers measure haemoglobin levels in the body and diagnose blood disorders and associated conditions.

Why Doctors Recommend Haemoglobin Estimation Test

The lab test for Hb estimation can provide a doctor with information about a person’s overall health. It may be prescribed as a part of a regular full-body health check-up, a complete blood count (CBC) test or to diagnose blood disorders or other health conditions. The most common reasons why a haemoglobin blood test may be prescribed by a healthcare provider include: -

• To Determine Overall Health: During a regular medical check-up, a doctor may prescribe a complete blood count test, which includes the haemoglobin test in its price, to monitor overall health and screen for illnesses like anaemia.
   
• To Identify the Cause of Certain Symptoms: Weakness, exhaustion, shortness of breath, or dizziness may be warning signs that indicate medical conditions like polycythaemia vera or anaemia. A haemoglobin test can be used to diagnose such illnesses.
   
• To Track the Efficacy of Treatments: The test can help keep a check on how well a treatment plan is working, meaning that the Hb blood test can help doctors see whether a particular treatment for conditions like anaemia or polycythaemia vera is working or if it needs to be modified.
   
• To Diagnose Anaemia: The standard reason for recommending a haemoglobin test is to diagnose anaemia. This is a condition where the blood does not have enough red blood cells to carry oxygen throughout the body. Anaemia can be caused by a variety of factors, including iron deficiency, vitamin B12 deficiency, and chronic disease.
   
• To Make Pre-Surgery Evaluations: Prior to surgery, a haemoglobin test may be asked to be performed to evaluate the patient's ability to endure the procedure and identify if a blood transfusion might be required.

While a low haemoglobin level may indicate a folate or vitamin B-12 deficiency, iron deficiency, hypothyroidism, chronic kidney disease, etc., on the other hand, blood conditions like polycythaemia vera, living at high altitudes, smoking, and dehydration are possible reasons that may cause higher-than-normal levels of haemoglobin.

Overall, doctors may recommend a hemoglobin blood test for numerous reasons, including evaluating overall health as part of a regular medical check-up, diagnosing or monitoring conditions like anaemia, tracking the efficacy of treatments, and making pre-surgery evaluations. Specifically, the test can help determine if red blood cells are carrying sufficient oxygen, which is vital for diagnosing conditions like anaemia or polycythaemia.

Preparations Before the Haemoglobin Estimation Test

Unless the healthcare provider advises otherwise, no specific preparations are required for a standard hemoglobin Hgb test. This is a simple blood test that measures the amount of haemoglobin in the blood, which helps diagnose conditions like anaemia or other associated blood disorders. However, if the doctor has ordered a panel of tests, the preparation might be different. Some of these tests might require fasting for a specific amount of time to ensure accuracy. Fasting is when an individual cannot eat or drink anything except water, typically 8-12 hours before the test. So, in case of uncertainty, it is always best to consult a healthcare provider for clarification.

What to Expect During the Procedure

A haemoglobin estimation test is straightforward with minimal discomfort. Here is how it is conducted: -

• A lab technician or phlebotomist gently cleans an area of an individual's arm with an antiseptic.
• Next, an elastic band is wrapped around the arm to make the veins more apparent.
• The technician will then insert a needle into one of the veins to draw a small blood sample.
• After collecting sufficient blood, technicians remove the needle and cover the pricked site with cotton or a bandage to stop any bleeding.
• The collected blood sample is then sent off to a laboratory where it will be analysed for its haemoglobin content.

The test is for hemoglobin levels, and results help evaluate the level of oxygen-carrying red blood cells.

Understanding the Test Results

A haemoglobin test result can show whether the levels are too low, as with anaemia, or too high. The results are compared to a normal range, that is, the reference range. This range may vary based on factors like age and sex. The test shows how high or low the haemoglobin level is, helping diagnose medical conditions associated with abnormal levels.
Low haemoglobin levels may be a sign of: -

• Anaemia
• Thalassemia
• Iron deficiency
• Liver disease
• Cancer and other diseases
• Blood loss, either from an injury, a heavy menstrual period, or other problems
• Lack of certain nutrients, such as iron or vitamin B-12
• Sickle cell disease.
• Autoimmune diseases.

High haemoglobin levels may be a sign of: -
Lung disease, such as chronic pulmonary obstructive disease (COPD) and pulmonary fibrosis.

• Certain types of kidney diseases, including kidney cancer.
• Heart disease
• Polycythaemia vera, a disease that causes the bone marrow to make too many red blood cells
• Sleep apnoea, a disorder that causes you to repeatedly stop breathing during sleep

Depending on the results, the healthcare provider may order follow-up tests to accurately identify the health concern. Moreover, the treatment depends on what’s causing the abnormal levels. So, discussing the haemoglobin estimation test result with a professional is necessary for proper diagnosis and treatment.

Factors That Can Influence Haemoglobin Levels in the Body?

Several factors affect the levels of haemoglobin in the body. Here are some of them:

Age

The normal range of haemoglobin is different for infants, children, and adults.

Gender

The male hormone, testosterone, has a stimulatory effect on the bone marrow, leading to higher levels of haemoglobin and RBCs, compared to women.

Diet

Iron is necessary for the formation of haemoglobin, and its deficiency can affect the production of RBCs.

Altitude

The amount of haemoglobin in the blood increases in people residing in higher altitudes.

Physical Activity

Regular exercise can increase haemoglobin and red blood cell mass.

Medication

Certain medications can cause anaemia by triggering the body's immune system. This causes red blood cells to break down earlier than normal, leading to lower levels of haemoglobin.

The meaning of the haemoglobin blood test serves many important functions in medical diagnostics. It can show how severe the condition is and help identify what’s causing the abnormal levels.

Ways to Improve Haemoglobin Levels Naturally and Safely

There are many ways in which people can increase and manage haemoglobin levels at home: -

• Increased Iron Intake: An individual with low levels of haemoglobin may benefit from consuming more iron-rich foods, such as meat, fish, poultry, organ meats, beans, legumes, eggs, nuts and seeds, and leafy vegetables.
   
• Higher Folate Intake: An adequate amount of folate is necessary for the development of RBCs. Consuming good sources of folate, such as spinach, beans (kidney beans), peanuts, fruits, whole grains, sunflower seeds, etc., can be beneficial.
   
• Increased Vitamin-C Intake: Citrus fruits, such as oranges, grapefruits, lemons, and limes, are rich in vitamin C, which improves iron absorption. These help the body absorb iron better.

Overall, a balanced diet can be very helpful in maintaining haemoglobin levels naturally and safely.
