Tuberculosis (TB) is a serious infectious disease that mostly affects the lungs.
If you were near someone who has TB, you should get tested. Testing helps keep you and others safe.
At Medicross Clinic and Urgent Care, we offer TB testing services. We help find TB quickly and reduce its spread.
What Is TB and How Does It Spread?
Mycobacterium tuberculosis causes TB. These germs spread when a sick person:
- Coughs
- Sneezes
- Talks
- Sings
You can breathe in the germs and get sick.
High-risk groups include:
- Healthcare workers
- Individuals who are employed in laboratories or shelters
- People with lowered immunity
A quick diagnosis is key. It helps avoid complications and can save your loved ones.
TB Testing: Skin Test vs Blood Test
There are two main types of TB tests:
1. Tuberculin Skin Test (TST)
- A small amount of fluid is injected under the skin
- Return within 48–72 hours to have it read
- Positive result: Indicates TB exposure; further tests confirm if it’s active
- Negative result: TB infection is not probable, but retesting may be required in case of recent exposure
2. Interferon-Gamma Release Assays (IGRAs) / Blood Test
- Determines the level of response of your immune system to TB bacteria
- Only requires one visit
- Perfect for individuals who have had the BCG injection or are unable to go back and have a skin test
Your healthcare provider will recommend the most appropriate test based on your risk factors and medical history.
Chances of Getting TB After Exposure
Being around someone with TB does not always mean you will get sick. Your risk depends on:
- Duration of exposure
- Severity of the other person’s infection
- Your overall health
Higher-risk groups include children, pregnant women and people with weak immune systems. Screening detects TB early for timely treatment.
What Happens If You Have a Positive TB Test
If your TB test is positive:
- Your physician may prescribe a chest X-ray or other tests
- If active TB is confirmed, treatment will begin to fight the infection
- TB should not be spread to other people due to delayed intervention
At Medicross Clinic, we assist you at every turn to ensure you receive the appropriate treatment.
What to Do If Exposed to Tuberculosis
If exposed to TB at work or in your community, it is crucial to take immediate action:
- Arrange a TB test to check for any infection.
- Although your first test is negative, during the next few weeks, you may experience some symptoms of TB.
- People with active TB must avoid close contact until cleared by a doctor.
- In high-risk persons, physicians may prescribe a medication to prevent latent TB from developing into active TB.
At Medicross Clinic and Urgent Care, we guide you through testing. We also give treatment recommendations based on your risk profile.
How Often Do You Need to Take a TB Test
