Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. It most commonly affects the lungs but can involve the lymph nodes, bones, kidneys, or other organs. Some people carry the bacteria without symptoms (latent TB), while others develop active disease that requires timely treatment.
At The Medical Group of New Jersey, our infectious disease specialists offer expert evaluation, modern treatment options, and long-term follow-up to prevent complications and protect the health of patients and their families.
Symptom Onset & Initial Evaluation
TB can appear in two forms, each with different symptoms and health implications.
Latent Tuberculosis Infection (LTBI)
- No symptoms
- Not contagious
- Detected only through screening tests
- Carries a future risk of developing active TB
Many people learn they have latent TB through workplace screenings, immigration exams, or evaluation after exposure to someone with active TB.
Active Pulmonary Tuberculosis
Symptoms often develop gradually and may include:
- Persistent cough lasting more than 2–3 weeks
- Unintentional weight loss
- Fever or night sweats
- Fatigue or decreased appetite
- Coughing up blood (in more advanced cases)
Extrapulmonary TB
Infection outside the lungs can cause:
- Swollen lymph nodes (lymphadenopathy)
- Back or joint pain
- Abdominal discomfort
- Headache or other neurologic symptoms
Evaluation
During your visit, your infectious disease specialist will:
- Review symptoms, your travel history, and any prior TB exposure
- Ask about immune conditions or medications that increase TB risk
- Perform a detailed physical exam
- Provide counseling on testing, infection prevention, and next steps
Evaluations are performed with discretion, compassion, and a focus on minimizing anxiety during the diagnostic process.
Diagnosis & Risk Assessment
A combination of tests is used to confirm TB infection and determine whether it is active or latent.
Testing May Include:
- TB blood test (IGRA – Quantiferon or T-Spot): Preferred for most adults
- Tuberculin skin test (PPD): Reliable screening tool that is quickly administered
- Chest X-ray or CT scan: Looks for lung abnormalities
- Sputum samples: Tested for TB bacteria through smear, culture, and PCR
Additional Testing When Needed:
- Imaging of other organs if TB is outside the lungs
- HIV testing (recommended for all newly diagnosed TB patients)
- Liver and kidney function labs before starting medication
Your care team will explain each test clearly and ensure you understand how results guide treatment.
Treatment & Long-Term Management
TB treatment is highly effective but requires a structured, multi-medication regimen. The infectious disease practitioners at The Medical Group of New Jersey follow the CDC and WHO guidelines to ensure safe and successful treatment.
Latent TB Infection (LTBI)
Complete treatment prevents future reactivation. Options may include:
- Once-weekly therapy for 3 months
- Daily therapy for 4 months
- Daily therapy for 6–9 months
Your provider will help choose the safest and most convenient treatment option.
Active TB Disease
Treatment typically includes:
- A combination of four medications for the first two months
- Followed by two medications for an additional 4 to 7 months
Throughout treatment, your specialist will:
- Monitor your liver function
- Check for medication side effects
- Ensure symptoms are improving
- Provide guidance on infection control (masking, isolation when needed)
Supportive Care Includes:
- Nutrition counseling for weight loss or fatigue
- Social support and education for care providers and family members
- Reporting and coordination with public health services (required by law)
Your care team will walk with you through every step to ensure a full recovery.
Monitoring & Follow-Up
Close follow-up is essential to ensure successful treatment and prevent relapse. During routine visits, your infectious disease specialist will:
- Review symptoms and medication adherence
- Monitor lab tests for safety
- Evaluate sputum tests until conversion is confirmed
- Adjust the medication plan if needed
- Provide ongoing education and reassurance
Most patients experience significant improvement within weeks; however, treatment must be continued until completion to ensure the infection is cured.
Prognosis & Preventive Care
With proper therapy, TB is highly treatable. The majority of patients recover fully when medications are taken consistently.
Prevention strategies include:
- Screening close contacts and household members
- Being evaluated after travel to TB-endemic regions
- Treating latent TB before it becomes active
- Avoiding smoking to support lung healing
- Keeping chronic illnesses (like diabetes) under good control
The infectious disease team at The Medical Group of New Jersey supports patients long after treatment ends, ensuring long-term health and peace of mind.
