Tuberculosis Test in Dubai, Understanding Tuberculosis
What is Tuberculosis?
Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs (pulmonary TB) but can also impact other parts of the body (extrapulmonary TB). TB is transmitted through the air when individuals with active pulmonary TB cough, sneeze, or speak, releasing tiny droplets containing the bacteria.
Symptoms of TB
The symptoms of TB can vary depending on the part of the body affected. Common symptoms of pulmonary TB include:
- Persistent cough lasting more than three weeks
- Chest pain
- Coughing up blood
- Unintentional weight loss
- Fever and chills
- Night sweats
- Fatigue
Extrapulmonary TB symptoms vary widely depending on the organs involved. For instance, TB of the spine may cause back pain, while TB meningitis can lead to headaches and neurological symptoms.
Risk Factors for TB
Several factors increase the risk of contracting TB, including:
- Close contact with individuals who have active TB
- Living or working in crowded environments such as prisons or shelters
- Weakened immune system due to conditions like HIV/AIDS, diabetes, or malnutrition
- Substance abuse
- Travel to or residence in regions with high TB prevalence

Molecular Tests
Molecular tests, such as the Xpert MTB/RIF assay, detect TB DNA and resistance to rifampicin, a key TB antibiotic, in a sputum sample. These tests are highly sensitive and provide rapid results.
Advantages of Molecular Tests
- High sensitivity and specificity
- Rapid results (within 2 hours for Xpert MTB/RIF)
- Can detect drug-resistant TB
Limitations of Molecular Tests
- Expensive and requires specialized equipment
- May not be widely available in all settings
TB Culture
TB culture involves growing Mycobacterium tuberculosis from a clinical specimen (e.g., sputum, tissue biopsy) in a laboratory. It is the gold standard for TB diagnosis and drug susceptibility testing.
Advantages of TB Culture
- Highly sensitive and specific
- Can provide information on drug resistance
Limitations of TB Culture
- Time-consuming (can take several weeks)
- Requires specialized laboratory facilities
