Walk-in TB testing in Westmont, IL for work, school and health requirements. Urgent Care Center of Westmont offers the TB skin test and TB blood test (IGRA), with form completion when required.
Tuberculosis (TB) testing shows whether you have been infected with TB germs. Many jobs, schools and programs require it. Urgent Care Center of Westmont, also known as Immediate Care Center of Westmont, offers two kinds of TB tests in Westmont, IL: the TB skin test and the TB blood test, also called an IGRA.
If you have a TB skin test, plan to come back in two to three days so we can read it. Our clinic is open seven days a week, which makes the return visit easier to fit in. You can walk in or check in online for either visit.
Key facts
Latent TB infection that later becomes active TB disease accounts for about 80 percent of U.S. TB cases, according to the CDC.
Latent TB can be treated with short courses of 3 or 4 months, which the CDC prefers over older 6- to 9-month regimens.
People born in or who often travel to countries where TB is common, and people who work in hospitals, shelters, prisons or nursing homes, have a higher chance of TB infection.
A past BCG vaccine does not rule out TB; a TB blood test is not affected by BCG.
Skin test or blood test?
TB skin test
A small amount of testing fluid is placed just under the skin of your forearm. The CDC says you return in two to three days for a provider to check the site for a reaction. The test is not complete until it is read.
TB blood test (IGRA)
A blood sample is taken and sent to a lab. The test measures how your immune system reacts to TB proteins. It needs only one visit for the draw. The CDC notes that TB blood tests are not affected by a past BCG vaccine, so they are often preferred for people who received BCG.
Your employer or school may require one type. Check your paperwork before you come in.
How TB testing works at our Westmont, IL clinic
We review your reason for testing, your health history, and any past TB tests or BCG vaccine. A provider helps choose the right test if your form allows either. After your test is read or your lab result returns, we explain what it means and complete your form.
What a result means
A positive result means TB germs are likely in your body. It does not tell whether you have inactive (latent) TB or active TB disease. More tests, such as a chest X-ray, are needed. A negative result means TB infection is unlikely, though your provider may test further if you have symptoms or a recent exposure.
People with latent TB have no symptoms and cannot spread it. Treatment can keep latent TB from becoming active disease. If you need follow-up, we will guide you on next steps.
Symptoms of TB disease and when to get help

The CDC lists these symptoms of active TB disease:
A bad cough that lasts 3 weeks or longer
Chest pain
Coughing up blood or sputum
Weakness, weight loss, or loss of appetite
Fever, chills, and night sweats
If you cough up more than a small amount of blood, have severe trouble breathing, or have chest pain, call 911 or go to the nearest emergency room.

Many people are tested because a job, school or program requires it. The CDC also suggests testing for people at higher risk of TB infection, including:
People born in, or who often travel to, countries where TB is common, such as parts of Asia, Africa and Latin America
People who live or lived in group settings like shelters, prisons or jails
Health care workers and others who work in hospitals, shelters, correctional facilities or nursing homes
Anyone who recently spent time with a person who has active TB disease
People with weakened immune systems, diabetes, or treatments that lower immunity, who are more likely to get sick if infected

Latent TB or TB disease?
Most positive tests in people without symptoms reflect latent TB, which does not spread
Treatment for latent TB
Preferred short courses: 3 months of once-weekly isoniazid plus rifapentine, 4 months of daily rifampin, or 3 months of daily isoniazid plus rifampin
Latent TB treatment is usually managed by a primary care clinician or the local health department. We will guide you on next steps. See X-ray imaging and lab testing.
Two. One to place the test and one two to three days later to read it.
I had the BCG vaccine. Which test should I get?
The CDC says TB blood tests are not affected by BCG, so a blood test is often preferred. Check what your form requires.
Does a positive test mean I am contagious?
Not necessarily. Most positive tests reflect latent TB, which does not spread. More testing is needed.
Can you fill out my work or school form?
Yes. Bring the form to your visit.
Can I shower after a TB skin test?
Yes. Normal activities, including showering, are fine. Do not cover the site with a bandage, scratch or rub it, or put lotion or cream on it. Then come back in 2 to 3 days to have the test read.
What happens if I miss my TB skin test reading?
The skin test must be read within its time window, about 2 to 3 days after placement. If that window passes, the test usually has to be placed again. Since we are open seven days a week, plan your reading visit before you get the test.
How long is treatment for latent TB?
The CDC prefers short courses that last 3 or 4 months, because they work well, are safe and are easier to finish. Older regimens of 6 or 9 months of isoniazid are still options when short courses do not fit.
Is a TB blood test better than a skin test?
Neither is right for everyone. The blood test needs only one visit and is not affected by a past BCG vaccine. The skin test is widely accepted and needs a second visit to read. Check which test your form allows, then ask your clinician.
