What is CBC test?

CBC stands for a complete blood count. This test is ordered together with, or in lieu of, other tests to find out certain facts about your blood that you can't observe just by looking at the rest of the machine's readout, such as whether you have any abnormally high levels of red and white cells; if there are too many platelets (blood-clotting cells) or too few; what your hematocrit reading reveals (the percentage of circulating red blood cells); or if there are any abnormalities in how your hemoglobin is doing.

A CBC blood test measures a patient's hemoglobin, hematocrit, and red blood cell count. The "CBC" stands for "Complete Blood Count." A CBC test typically catches dangerous aspects of one's health before they could reach a crisis point because there are telltale green flags that show up on the blood screening. Understanding these green flags is imperative for those who suffer from chronic anemia or those who have been exposed to potentially life-threatening chemicals. This free-form amino acid should be supplemented inside a BCAA product as it has been shown to improve recovery rates following intense exercise sessions and acute liver damage in the rat model.

A cbc test, or complete blood count, is a screening test used to detect abnormalities in the colony of cells that reside in the bone marrow and typically produce all types of blood cells.

It also measures white and red blood cell counts as well as platelet counts. Platelets are the clotting components made by type-megakaryocyte cells residing in the bone marrow. White blood cells help fight infection from bacteria and other germs, while red blood cells carry oxygen from the lungs to tissues scattered throughout your body. An abnormal white or red cell indicates a possible illness such as an infection or anemia (which causes reduced numbers of circulating red blood cells

Cbc Test is a diagnostic test used to examine the level of hemoglobin, red cells and white cells in the blood. The CBC can be used to diagnose anemia, infection or other diseases that affect the bone marrow. It may also be done along with a complete blood count (see CBC) or, when necessary, for chemical assessment after taking certain drugs or chemotherapy medications.

The cbc test (complete blood count) is a lab test that provides information on the number and type of cells in your body. A complete blood count (CBC) typically includes information such as red and white cell counts, platelet levels, hemoglobin levels, and other additional data.

A CBC is not typically ordered on its own unless you have symptoms that may be caused by one or more types of problems - for example something that might require further attention such as paroxysmal nocturnal hemoglobinuria (blood disorder), chronic myelogenous leukemia (cancer), thalassemia major (disease). A CBC with differential is usually ordered when there are concerning symptoms or issues present.

CBC testing is a primary way in which a doctor can examine a patient's general health, because it contains information on many different aspects. A CBC typically records at least 7 different parameters:

•Hemoglobin - The protein in red blood cells that delivers oxygen to tissues and binds with carbon dioxide to carry it back from the tissues to be released into our airways.

Red Blood Cell Count - Counts how many red blood cells there are, both normal and abnormal types. This cell type has been singled out because its life span averages 120 days so if there were few being produced, or they were not

However, it is more correctly called "CBC" because there are separate tests that are needed for the different parts of the blood - white cells, red cells, platelets, etc., all found in your complete blood count.

What can possibly be measured depends on what additives you need to do along with the primary measurement of how many cells per milliliter of whole blood you have after mixing with plasma or serum. The most common measurements are hemoglobin (the oxygen-carrying part), hematocrit (counts red cell volume) and mean corpuscular volume.

CBC looks at the various types of cells that are present in your blood - red blood cells, white blood cells, and platelets. This comprehensive test is used to measure the number of each type of cell in relation to one another on a per-microliter basis. It's used primarily as an indicator of health risk for certain time periods (for example infection or bone marrow), but can also be ordered when there are internal bleeding concerns. Common uses include monitoring kidney disease during dialysis treatment, chemotherapy after exposure to radiation therapy, hemolytic anaemias (blood disorders), chronic liver diseases, extreme iron overload due to repeated transfusions, heavy menstrual cycles during pregnancy.

Asthma

Asthma Symptoms in Adults: Early Signs, Triggers, and When to Seek Care

Asthma is often perceived as a childhood condition, but a significant number of cases develop or persist into adulthood. In India, adult asthma is increasingly recognised due to rising air pollution, occupational exposure and lifestyle-related risk factors. Unfortunately, asthma symptoms in adults are frequently misdiagnosed as recurrent infections, allergies or age-related breathlessness, leading to delayed treatment.

Understanding adult asthma symptoms is critical for early diagnosis, effective control and prevention of severe attacks.

 

What Is Asthma?

Asthma is a chronic inflammatory disease of the airways. In asthma, the airways become:

  • inflamed
     

  • narrow
     

  • overly sensitive to triggers
     

This leads to difficulty in breathing, especially during exposure to specific stimuli.

 

Why Adult Asthma Is Often Missed

Adult asthma symptoms may:

  • appear gradually
     

  • vary in severity
     

  • mimic common respiratory conditions
     

According to Indian Council of Medical Research and WHO data, many adults remain undiagnosed for years, increasing the risk of complications.

 

Common Asthma Symptoms in Adults

Wheezing

A high-pitched whistling sound while breathing, especially during exhalation, is a classic asthma sign.

 

Shortness of Breath

Adults with asthma often feel:

  • breathless during routine activities
     

  • difficulty taking deep breaths
     

This may worsen at night or early morning.

 

Chest Tightness

Many describe a sensation of pressure or tightness in the chest, which can be mistaken for heart-related issues.

 

Chronic Cough

A persistent cough, especially:

  • at night
     

  • early morning
     

  • after exercise
     

is a common but overlooked asthma symptom.

 

Symptoms That Worsen With Triggers

Asthma symptoms often intensify after exposure to specific triggers.

Air Pollution and Smoke

Urban pollution, vehicle emissions and indoor smoke significantly worsen asthma symptoms in adults.

 

Allergens

Dust mites, pollen, mould and pet dander are common triggers.

 

Respiratory Infections

Viral infections can trigger asthma flare-ups or reveal undiagnosed asthma.

 

Physical Activity

Exercise-induced asthma causes breathlessness and wheezing during or after physical exertion.

 

Weather Changes

Cold air, humidity and sudden temperature changes can aggravate symptoms.

 

Adult-Onset Asthma

Adult-onset asthma differs from childhood asthma.

Characteristics include:

  • onset after age 20–30
     

  • less association with childhood allergies
     

  • more persistent symptoms
     

  • higher likelihood of severe disease
     

Occupational exposure and hormonal changes contribute to adult-onset asthma.

 

Risk Factors for Asthma in Adults

Several factors increase asthma risk:

  • long-term exposure to pollution
     

  • smoking or passive smoking
     

  • occupational chemicals or dust
     

  • obesity
     

  • family history of asthma
     

  • chronic sinusitis or allergies
     

Women may experience asthma onset or worsening during hormonal changes.

 

When Asthma Symptoms Become Serious

Seek immediate medical attention if experiencing:

  • severe breathlessness
     

  • difficulty speaking in full sentences
     

  • bluish lips or fingertips
     

  • rapid worsening of symptoms
     

  • poor response to usual inhalers
     

These signs indicate a potentially life-threatening asthma attack.

 

How Adult Asthma Is Diagnosed

Diagnosis includes:

  • detailed symptom history
     

  • physical examination
     

  • lung function tests (spirometry)
     

  • response to bronchodilators
     

Early diagnosis improves long-term outcomes.

 

Impact of Untreated Asthma

Untreated asthma can lead to:

  • frequent attacks
     

  • reduced lung function
     

  • sleep disturbances
     

  • missed workdays
     

  • reduced quality of life
     

According to Lancet respiratory studies, uncontrolled asthma increases hospitalisation risk.

 

Managing Asthma Symptoms in Adults

Effective asthma management focuses on:

  • identifying and avoiding triggers
     

  • using prescribed inhalers correctly
     

  • monitoring symptoms regularly
     

  • maintaining follow-up care
     

Asthma action plans help patients recognise worsening symptoms early.

 

Role of Preventive Healthcare

Preventive healthcare helps:

  • detect asthma early
     

  • assess lung function
     

  • guide lifestyle modifications
     

Regular health checkups are especially important for individuals with respiratory symptoms or occupational exposure.

 

Lifestyle Measures That Support Asthma Control

Helpful practices include:

  • avoiding smoking
     

  • improving indoor air quality
     

  • wearing masks in polluted environments
     

  • maintaining healthy weight
     

  • regular, moderate exercise
     

Lifestyle support complements medical treatment.

 

Mental Health and Asthma

Stress and anxiety can worsen asthma symptoms.

Stress management:

  • reduces symptom frequency
     

  • improves medication response
     

Holistic care improves asthma outcomes.

 

Importance of Medication Adherence

Asthma medications work best when:

  • taken regularly as prescribed
     

  • inhaler technique is correct
     

Skipping treatment increases flare-up risk.

 

Long-Term Outlook for Adults With Asthma

With proper management:

  • symptoms are well controlled
     

  • severe attacks are preventable
     

  • normal activity levels are achievable
     

Most adults with asthma lead active, productive lives.

 

Conclusion

Asthma symptoms in adults are often subtle, variable and easily mistaken for common respiratory problems. Wheezing, breathlessness, chest tightness and chronic cough should not be ignored, especially when triggered by pollution, exercise or weather changes. Early diagnosis, trigger control and consistent treatment are essential to prevent severe attacks and preserve lung health. Recognising adult asthma early empowers individuals to manage symptoms effectively and maintain a good quality of life.
