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.

Why Recurring Sore Throat Can Be a Serious Issue

Why Recurring Sore Throat Can Be a Serious Issue

A sore throat is a common complaint. Most of us experience it during seasonal changes, after a cold, or when we catch the flu. But what if your sore throat keeps coming back again and again? While many people dismiss it as a minor irritation, a recurring sore throat can actually signal more serious health issues that require proper attention.

What is a recurring sore throat?

A recurring sore throat refers to repeated or persistent throat discomfort that comes back multiple times in a year or lasts longer than usual. Normally, a viral sore throat improves within a week. If the problem lingers beyond 10 days or returns frequently, it falls into the category of chronic or recurring sore throat.

Why is it serious?

  1. Undiagnosed infections
    A single sore throat from a virus is not concerning. But if bacterial infections like strep throat keep coming back, they may damage the throat and spread to other parts of the body if untreated.
     

  2. Inflammation and tissue damage
    Constant irritation from allergies or acid reflux can harm the delicate tissues of the throat. Over time, this may affect your voice and overall throat function.
     

  3. Underlying medical conditions
    Recurring sore throat can be linked to issues like gastroesophageal reflux disease (GERD), allergies, tonsil problems, or immune system weakness. In some cases, it may also be an early warning sign of more serious diseases such as tumors.
     

  4. Complications
    Recurrent infections can lead to abscesses around the tonsils, ear infections, or sinus problems. Inadequate or repeated antibiotic use can also cause resistance.
     

  5. Impact on daily life
    A constant sore throat affects your eating, speaking, sleeping, and quality of life. It leads to repeated doctor visits, discomfort, and stress.
     

Common causes of recurring sore throat

  • Bacterial infections like strep throat or chronic tonsillitis
     

  • Viral infections that linger or reactivate
     

  • Allergies that trigger postnasal drip and throat irritation
     

  • Acid reflux or GERD causing stomach acid to irritate the throat
     

  • Environmental irritants such as smoke, dust, and pollution
     

  • Mouth breathing during sleep due to nasal blockage
     

  • Immune weakness making you prone to repeated infections
     

Warning signs to watch for

You should never ignore these symptoms if they accompany a recurring sore throat:

  • Sore throat lasting longer than 2–3 weeks
     

  • Difficulty swallowing or breathing
     

  • Lump or swelling in the throat or neck
     

  • Persistent hoarseness or voice changes
     

  • Unexplained weight loss
     

  • Blood in saliva or phlegm
     

  • Fever with night sweats
     

These are red flags that need immediate medical evaluation.

How lab tests help

Lab tests play a critical role in finding out why you have a recurring sore throat. Some useful investigations include:

  • Throat swab or culture to identify bacterial infections
     

  • Rapid antigen test for strep for quick diagnosis
     

  • Complete Blood Count (CBC) to detect infection or immune problems
     

  • CRP and ESR to check inflammation
     

  • Allergy tests to identify triggers like dust or pollen
     

  • Thyroid function tests to rule out thyroid-related throat problems
     

  • Reflux evaluation if GERD is suspected
     

  • Immune status tests if infections are unusually frequent
     

Through SecondMedic/Thyrocare, these tests can be arranged easily, giving you faster results and treatment planning.

Treatment and prevention

The treatment of recurring sore throat depends on its cause:

  • Bacterial infections are treated with antibiotics prescribed by a doctor. Completing the full course is essential.
     

  • Viral infections usually require rest, hydration, and symptom management.
     

  • Acid reflux can be controlled with lifestyle changes like avoiding late meals, reducing spicy foods, and medications if required.
     

  • Allergies can be managed by identifying and avoiding triggers, along with prescribed medicines.
     

  • Tonsil problems may require surgical removal if infections are frequent and severe.
     

Preventive steps include:

  • Staying hydrated
     

  • Avoiding smoking and exposure to polluted air
     

  • Maintaining good throat hygiene
     

  • Managing acid reflux through diet and posture
     

  • Strengthening immunity with balanced nutrition and rest
     

When to see a doctor

If you suffer from frequent sore throats or if your symptoms come with any red flags, consult a healthcare professional without delay. Early evaluation prevents complications and ensures better outcomes.
