Welcome to Ganesh Diagnostics, your trusted destination for accurate and timely diagnostic services. As the leading diagnostic center in India, we specialize in detecting and diagnosing various medical conditions, including tuberculosis. Today, we will discuss the active tuberculosis stage, its signs and symptoms, diagnosis, treatment, and prevention strategies.

Active Tuberculosis Stage: An Overview

Active tuberculosis refers to the stage of the disease when the Mycobacterium tuberculosis bacteria actively multiply in the body, leading to the onset of symptoms and potential transmission to others. This stage is characterized by the presence of infectious bacteria in the respiratory system or other parts of the body.

Signs of Active Tuberculosis

Recognizing the signs of active tuberculosis is crucial for early detection and timely intervention. 

Here are some common signs that may indicate the active stage of the disease:

Persistent cough

A persistent cough that lasts for more than three weeks is one of the key signs of active tuberculosis. The cough may produce phlegm or blood in some cases.

Fatigue and weakness

Active tuberculosis can cause extreme tiredness, weakness, and a general feeling of malaise. If you experience persistent fatigue without any apparent reason, it's essential to seek medical attention.

Unintentional weight loss

Sudden and unexplained weight loss is another common symptom of active tuberculosis. If you notice a significant drop in your weight without changes in your diet or exercise routine, it's important to get evaluated.

Night sweats

Experiencing excessive sweating, particularly during sleep, is a symptom that should not be ignored. Night sweats can be indicative of several medical conditions, including active tuberculosis.

Symptoms of Active Tuberculosis

In addition to the signs mentioned above, active tuberculosis can manifest with various symptoms, depending on the affected area of the body. 

Here are some specific symptoms that may occur:

Active Pulmonary Tuberculosis

When tuberculosis affects the lungs, symptoms may include chest pain, shortness of breath, coughing up blood, and persistent fever.

Active Extrapulmonary Tuberculosis

Tuberculosis can also affect other parts of the body, such as the lymph nodes, bones, joints, kidneys, and brain. Symptoms may vary depending on the site of infection but can include swelling, pain, urinary problems, and neurological symptoms.

Diagnosis of Active Tuberculosis

Prompt and accurate diagnosis of active tuberculosis is essential to prevent its spread and initiate appropriate treatment. At Ganesh Diagnostics, we offer a range of diagnostic tests that aid in the detection of active tuberculosis. Some of the tests and services we provide include:

Mantoux Tuberculosis Test

This skin test helps determine if an individual has been exposed to tuberculosis bacteria. It involves injecting a small amount of purified protein derivative (PPD) into the forearm and observing the reaction after 48 to 72 hours.

Mycobacterium Tuberculosis DNA PCR Quantitative

This advanced molecular test detects and quantifies the genetic material of Mycobacterium tuberculosis in a patient's sample. It offers high sensitivity and specificity in diagnosing active tuberculosis.

CS for Mycobacterium TB Test

This test involves culturing the patient's sputum or other body fluids to isolate and identify Mycobacterium tuberculosis bacteria. It helps confirm the diagnosis of active tuberculosis.

Treatment for Active Tuberculosis

Once diagnosed, it is vital to initiate treatment for active tuberculosis promptly.

Here are the primary components of tuberculosis treatment:


The cornerstone of tuberculosis treatment is a combination of antibiotics that effectively target the Mycobacterium tuberculosis bacteria. The treatment typically involves a regimen of multiple drugs taken for a specified duration, usually six to nine months. It is crucial to take the medications as prescribed and complete the full course to ensure successful treatment.

Directly Observed Therapy (DOT)

To enhance treatment adherence and minimize the risk of drug resistance, we offer a DOT program where our healthcare staff directly observes patients taking their medications. This approach ensures that the treatment regimen is followed correctly.

Regular Monitoring

Throughout the treatment process, we closely monitor the patient's progress through regular follow-up visits and diagnostic tests. This monitoring helps assess the effectiveness of the treatment and make any necessary adjustments.

Active Tuberculosis Prevention and Management

Preventing the transmission of tuberculosis and effectively managing the disease is essential for controlling its spread. 

Here are some key measures for active tuberculosis prevention and management:


The Bacillus Calmette-Guérin (BCG) vaccine is a preventive measure that can reduce the risk of severe forms of tuberculosis in children. It is recommended for infants in areas with a high prevalence of tuberculosis.

Infection Control

Proper infection control measures are crucial in healthcare facilities to prevent the transmission of tuberculosis. These measures include good ventilation, the use of masks by healthcare workers, and the prompt identification and isolation of individuals with active tuberculosis.

Contact Tracing

Identifying and screening individuals who have been in close contact with an active tuberculosis patient is essential for early detection and treatment. We offer contact tracing services to ensure timely intervention and prevent further spread of the disease.

Education and Awareness

Raising awareness about tuberculosis, its symptoms, and the importance of early diagnosis and treatment is vital in preventing its spread. We conduct educational programs and provide informational resources to promote awareness in the community.
