The mission of Collin County Tuberculosis Clinic is to prevent, control, and eliminate the spread of TB in Collin County. We plan to accomplish this mission by developing effective communication with providers and the public, providing quality diagnostic and treatment services, strengthening our surveillance and epidemiologic investigations, and improving the public's knowledge about the disease. As a county health department, we are well-equipped and qualified to perform all of the state's mandated tasks to accomplish our mission.
Tuberculosis (TB) is a serious disease. It was once the leading cause of death in the U.S. TB is caused by the bacteria
Mycobacterium tuberculosis and is spread through the air. Most TB disease occurs in the lungs but TB can affect any part of the body.
For some people who breathe in the TB germs, the germs are not active and may stay that way for a short time or for years. Having a TB infection (also known as Latent TB Infection or LTBI) does not mean that the person has active TB disease. Some people with a TB infection never develop TB disease. However, for people with a weakened immune system or other risk factors, the TB germs may become active later in life and cause the active disease. People with TB infections do not look or feel sick and are not contagious.
In people with active TB disease, the following symptoms may be present:
- Feeling of sickness, weakness
- Weight loss
- Night sweats
- Coughing, persistent
- Coughing up blood
A person with
active TB can pass the TB germs to others usually through coughing. Individuals with the following risk factors are more likely to develop TB:
- A weakened immune system, such as persons with HIV/AIDS, leukemia, cancer , diabetes, and other serious illnesses
- Taking medicines such as TNF-alpha which may affect the immune system
- Recently infected with TB in the last two years
- Treated in the past for TB, but did not complete treatment or was not treated with the proper medications
The Collin County Health Care Services Tuberculosis Clinic offers screening for TB either through a TB skin test or a blood test to tell if you have the TB germs. Visit the
Tuberculosis Elimination—Diagnosis Services section for more information. It is important that you obtain this test if you live with or have frequent close contact with someone with active TB or if you have HIV/AIDS. If you live with someone who has signs of TB the health department may ask you to be tested.

Tuberculosis Elimination—Diagnostic Services by Appointment Only
The Collin County Health Care Services TB Clinic provides TB screening in the form of a TB blood test (Interferon Gamma Release Assay or IGRA) to county residents. In a recent report issued by DSHS on their website
(The Big Picture, Risk Factors Associated with TB Cases), they note that "although the tuberculin skin test has been the conventional screening method in Texas, regional and local tuberculosis programs are adopting the IGRA test as the standard tool to screen for TB." Individuals less than 5 years of age are eligible for a TB skin test (TST). Both the IGRA and TST are available by appointment through the TB clinic on Tuesdays and Wednesdays from 8-11:00 a.m. and 1-3:00 p.m. Please note the following important reminders regarding TB Testing:
|Type of Visit/Service--By Appointment Only
|Office Visit (physician) for persons requesting a change in immigration status through their civil surgeons
|TB Skin Test (for individuals less than 5 years of age); requires 2 visits
||First Visit (Tuesday), Second Visit (Thursday)
First Visit (Wednesday), Second Visit (Friday)
|TB blood test (IGRA), brand name "T-Spot"

TB Blood (IGRA, "T-Spot")--for individuals 5 years of age and older
Any person over the age of 5 years requesting or needing a TB screening will be offered a "T-Spot" which is the brand name of the IGRA blood test used by our clinic. In most cases, the IGRA test results are available in 3-4 business days, and individuals may be notified of negative test results by phone. Any person needing a copy of negative test results may request a copy. Depending on the reason for testing, the copy of the negative results may be mailed to the patient or may require a return appointment to pick up the results during clinic hours.
TB Skin Test (TST)--for individuals less than 5 years of age
Please Note that appointments for requesting TB skin testing is highly recommended and
patients are required to make two visits to the clinic. The first visit is to receive the test, and the second visit, which takes place after 48 to 72 hours, is for the test to be checked by the TB nurse. Please note the following important reminders:
- You will be informed of the date when the TB Skin Test is to be read prior to administration.
- If you cannot return for the reading, the screening test should be rescheduled.
- You will receive documentation of the receipt of a TB Skin Test screening when results are read.

- TB Skin Tests administered elsewhere will not be read by health department staff except in special circumstances. Readings will be done only when full documentation of the TB Skin Test is provided, including when and where the test was administered.
Any person having a positive TB blood test (IGRA, "T-Spot") or skin test (TST) that was placed and read by Collin County staff will be given a chest x-ray referral form to take to a radiology center to receive a necessary chest x-ray. Clinic staff will also schedule for a follow-up evaluation with the Collin County TB physician.
