The doctors use a number of tests to diagnose anemia. Hb (hemoglobin) is one of the key indicators used in diagnosis. A hemoglobin test is a blood test that measures how much hemoglobin you have in your red blood cells. A hemoglobin test is generally used for detecting:

In addition, a hemoglobin test can also be carried out to assess bone marrow's response to treatment, evaluate possible blood donation and check the levels of red blood cells in the body. There are certain conditions that may interfere with the results of the hemoglobin test. In such cases, it is recommended to get the test done again.

For the hemoglobin test, a sample of your blood is taken and tested in a clinical laboratory [read more about the process here]. The results are expressed as grams of hemoglobin per deciliter (g/dL) or micrograms per liter (mcg/L). Normal range for this test is 12g/dL - 18g/dL (12.1-18.0 g/L) for adults and 9g/dL - 13g/dL (9.0-13.3 g/L) for children. If the test result comes out to be less than 7 gm, it can indicate a serious condition known as severe anemia. In some cases, the doctors may order follow-up tests to assess the current condition of the patient.

Apart from the hemoglobin test, certain other blood tests can be used for detecting low RBCs (RBC count) or abnormal types of RBC (red cell indices) or hemoglobin (Hb). These include complete blood count tests, reticulocyte tests, iron tests, and red blood cell indices.

In some cases, the doctor may opt to do a bone marrow aspiration and exam to check for any abnormalities in the bone marrow cells. In such cases, it of red blood cells is karyotype to rule out chromosomal disorders.

The most common reason for having an inadequate number of red blood cells in the body is an iron deficiency or anemia. Iron plays a significant role in the production of hemoglobin, which is responsible for carrying oxygen from the lungs to the tissues of other parts of the body. Hence, people suffering from iron are known as sickle cell trait. The tests include:

Complete blood count test - The complete blood cell count (CBC) is a routine test that checks the different components of your blood like number of red blood cells, white blood cells and platelets. It also has information about the size and hemoglobin content in each of these cells. A CBC includes tests for the following:

Reticulocyte test - This is a blood test that measures the reticulocytes (immature red blood cells) in the bloodstream. A high level of reticulocytes can indicate increased production of red blood cells by the bone marrow to compensate for anemia, or destruction of very early stage RBCs which are still unable to mature.

Iron tests - Iron is an essential component for RBC production. A test to assess the iron level in your blood is called a serum ferritin test, which measures the amount of iron stored in the body's cells and tissues. Another way to evaluate low iron levels is by carrying out a transferrin saturation test. In this case, the lab technician will extract serum from your blood sample and measure the amount of transferrin protein present in it. Transferrin is a protein that carries iron to the bone marrow where red blood cells are produced. Thus, if there is an insufficient amount of transferrin protein present in the serum, it shows that there is an inadequate level of stored iron.

Hemoglobin tests - A hemoglobin test is generally carried out to detect anemia, especially if the result of CBC tests are inconclusive. During this test, a small sample of blood is collected from your vein and sent to the laboratory for analysis. The test measures the amount of hemoglobin in your red blood cells.

Red cell indices - Red cell indices are tests that measure the size and hemoglobin content of the red blood cells. The values obtained from these tests can be used to detect anemia and other blood disorders.

Karyotype test - It is a lab test used to evaluate chromosomal abnormalities in red blood cells or bone marrow cells

Low blood cell counts also have other causes, such as infections or tumors. In some cases, low blood cells may indicate a more serious condition like bone marrow failure which requires immediate medical intervention to save the patient from death.

Thus, if you are suffering from any of these conditions and symptoms and suspect that you may be anemic, check with your doctor for the necessary tests to confirm or rule out your suspicions. Early detection and treatment of anemia can save you from serious complications like heart attacks, strokes, blood clots, etc.

Health Risks of Sedentary Lifestyle: Why Sitting Too Much Can Harm Your Health

Modern lifestyles have become increasingly sedentary. With the rise of desk jobs, digital devices and long working hours, many individuals spend a significant portion of their day sitting. While technology and convenience have improved productivity, they have also contributed to reduced physical activity.

Understanding the health risks of a sedentary lifestyle is essential for preventing chronic diseases and maintaining overall wellbeing.

 

What Is a Sedentary Lifestyle?

A sedentary lifestyle refers to a pattern of behavior characterized by prolonged sitting or inactivity with minimal physical movement.

Common examples include:

  • Sitting at a desk for long hours
     

  • Watching television for extended periods
     

  • Spending significant time on computers or smartphones
     

  • Limited engagement in physical exercise
     

When the body remains inactive for long durations, various physiological functions may become impaired.

 

1. Increased Risk of Obesity

Physical inactivity reduces calorie expenditure.

When calorie intake exceeds the energy burned through activity, excess calories are stored as body fat.

This can lead to weight gain and increase the risk of obesity.

Obesity is a major risk factor for several chronic health conditions.

 

2. Higher Risk of Cardiovascular Disease

Prolonged sitting has been associated with increased risk of heart disease.

Sedentary behavior may contribute to:

  • Elevated blood pressure
     

  • Increased cholesterol levels
     

  • Reduced blood circulation
     

These factors increase the likelihood of cardiovascular complications over time.

 

3. Increased Risk of Type 2 Diabetes

Physical activity helps regulate blood sugar levels.

A sedentary lifestyle may impair the body’s ability to use insulin effectively, leading to insulin resistance.

Over time, this can increase the risk of developing type 2 diabetes.

 

4. Poor Metabolic Health

Metabolism refers to the body’s ability to convert food into energy.

Long periods of inactivity may slow metabolic processes and reduce the body’s efficiency in managing glucose and fat levels.

This can contribute to metabolic syndrome.

 

5. Musculoskeletal Problems

Sitting for extended periods can strain muscles and joints.

Common issues include:

  • Lower back pain
     

  • Neck stiffness
     

  • Shoulder discomfort
     

  • Poor posture
     

These problems are particularly common among office workers.

6. Reduced Mental Wellbeing

Physical activity plays a significant role in supporting mental health.

Sedentary behavior may contribute to:

  • Increased stress levels
     

  • Reduced mood
     

  • Lower energy levels
     

Regular movement helps improve mental wellbeing.

 

7. Increased Risk of Premature Mortality

Studies have shown that prolonged inactivity may increase the risk of early death due to chronic diseases.

Maintaining an active lifestyle significantly improves long-term health outcomes.

 

Sedentary Lifestyle in the Indian Context

Urbanization and technological advancements have led to more sedentary work environments in India.

Long commuting hours, desk-based professions and digital entertainment have reduced physical activity levels for many individuals.

As a result, lifestyle-related diseases such as diabetes and heart disease have increased significantly in recent years.

Public health initiatives now emphasize the importance of regular physical activity to counter these trends.

 

How to Reduce Sedentary Behavior

Take Frequent Movement Breaks

Stand up and stretch every 30–60 minutes during work.

Incorporate Walking into Daily Routine

Short walks during breaks can improve circulation and energy levels.

 

Use Active Workstations

Standing desks or adjustable workstations encourage movement.

 

Exercise Regularly

Engage in moderate physical activity such as walking, cycling or yoga.

Health guidelines recommend at least 150 minutes of exercise per week.

Limit Screen Time

Reducing recreational screen time encourages more active habits.

 

Benefits of an Active Lifestyle

Increasing daily physical activity provides several health benefits:

  • Improved cardiovascular health
     

  • Better weight management
     

  • Enhanced mental wellbeing
     

  • Stronger muscles and bones
     

  • Improved metabolic function
     

Even small lifestyle changes can make a significant difference over time.

When to Seek Medical Advice

Consult a healthcare professional if you experience:

  • Persistent back pain
     

  • Unexplained weight gain
     

  • Chronic fatigue
     

  • Signs of metabolic disorders
     

Early intervention can help manage health risks effectively.

 

Conclusion

A sedentary lifestyle may significantly impact physical and mental health. Prolonged sitting and lack of movement increase the risk of obesity, cardiovascular disease, diabetes and musculoskeletal problems.

Adopting an active lifestyle that includes regular movement, exercise and healthy habits is essential for maintaining overall wellbeing.

Simple changes such as standing frequently, walking regularly and engaging in physical activity can greatly reduce the health risks associated with sedentary behavior.

Maintaining an active lifestyle is one of the most effective ways to support long-term health and prevent chronic disease.
