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.

Is it Allergy or Asthma

Is it Allergy or Asthma? How to Know the Difference

Have you ever found yourself sneezing, coughing, or gasping for air and wondering whether it's just a seasonal allergy or something more serious like asthma? You're not alone. Many people confuse the symptoms of allergies and asthma because they often overlap. However, knowing the difference between the two is crucial for getting the right treatment and managing your condition effectively.

In this blog, we’ll explain what allergies and asthma are, how they’re related, what makes them different, and how to know what you’re dealing with.

 

What Are Allergies?

Allergies happen when your immune system reacts to a harmless substance like pollen, dust, or pet dander as if it were dangerous. These substances are called allergens. When you're exposed to an allergen, your body releases chemicals like histamine that cause allergy symptoms.

Common Allergy Symptoms:

  • Sneezing

  • Runny or stuffy nose

  • Itchy eyes, nose, or throat

  • Watery eyes

  • Skin rashes or hives

  • Coughing (especially at night)

  • Fatigue
     

These symptoms usually appear quickly after exposure to the allergen and can range from mild to severe.

 

What Is Asthma?

Asthma is a chronic lung disease that inflames and narrows your airways, making it hard to breathe. Asthma can be triggered by many things—including allergens. When asthma flares up, it’s called an asthma attack or asthma episode.

Common Asthma Symptoms:

  • Shortness of breath

  • Chest tightness or pain

  • Wheezing (a whistling sound when breathing)

  • Coughing (often worse at night or early morning)

  • Trouble sleeping due to breathing issues
     

Asthma symptoms can come and go. They may be triggered by allergens, cold air, exercise, smoke, or even stress.

 

Are Allergies and Asthma Related?

Yes, they are! Many people who have allergies also have asthma. This condition is called allergic asthma. In fact, allergens like pollen, mold, pet dander, and dust mites are common asthma triggers.

When you breathe in something you're allergic to, your airways can become inflamed, making it difficult to breathe—this is where allergies and asthma overlap.

 

Key Differences Between Allergy and Asthma

Feature

Allergy

Asthma

Affects

Eyes, nose, throat, skin

Lungs and airways

Symptoms

Sneezing, itching, watery eyes, rashes

Wheezing, breathlessness, chest tightness

Trigger

Pollen, dust, food, pets, etc.

Allergens, exercise, cold air, pollution

Time of Symptoms

Immediate (within minutes)

May develop slowly or suddenly

Treatment Focus

Antihistamines, avoiding allergens

Inhalers, bronchodilators, steroids

While allergies mostly affect the upper airways (like your nose and throat), asthma affects the lower airways (your lungs).

 

How to Know What You Have

1. Track Your Symptoms

Keep a journal of what symptoms you experience, when they occur, and what you were doing at the time. Are you only sneezing and sniffling when the pollen count is high? Do you wheeze and cough after jogging or being around pets?

2. Get Allergy Testing

Your doctor may recommend a blood test or skin prick test to find out what you’re allergic to. This is especially helpful if your symptoms are triggered by specific things like pollen or food.

3. Do a Lung Function Test (Spirometry)

This simple breathing test helps measure how well your lungs work. If you have asthma, the test may show that your airways are narrowed or inflamed. The results also help doctors decide how severe your asthma is.

4. Observe When Symptoms Occur

If your symptoms occur mostly in certain seasons (like spring or fall), they may be due to allergies. If they happen during exercise or at night, it could be asthma.

 

Can You Have Both?

Absolutely. Many people live with both allergies and asthma. In these cases, managing one helps manage the other. For example, taking allergy medication can help reduce asthma symptoms triggered by allergens.

That’s why it's important to get a proper diagnosis. Treating only one condition when you have both may not bring full relief.

 

Treatment Options

For Allergies:

  • Antihistamines – reduce sneezing and itching

  • Nasal sprays – ease a runny or blocked nose

  • Eye drops – soothe itchy, watery eyes

  • Allergy shots (immunotherapy) – gradually reduce your sensitivity to allergens
     

For Asthma:

  • Inhalers – deliver medicine directly to the lungs

  • Long-term medications – reduce airway inflammation

  • Rescue inhalers – for quick relief during an attack

  • Lifestyle changes – avoid triggers, keep your environment clean
     

Always consult a doctor before starting any treatment.

 

When to See a Doctor

You should see a healthcare provider if:

  • You have trouble breathing or frequent coughing

  • Symptoms interfere with daily life or sleep

  • Over-the-counter allergy medicine isn’t helping

  • You need to use your asthma inhaler more often than usual
     

Early diagnosis and treatment can prevent complications and improve your quality of life.

 

Final Thoughts

Understanding the difference between allergies and asthma is the first step in managing your health. Both are common, manageable conditions—but only if you know what you're dealing with. By observing your symptoms and getting tested, you can find the right path to relief.

 

Conclusion: Is it Allergy or Asthma? How to Know the Difference
