I Wish I Had Known About the TB Blood Test

I participated in an Influencer Activation on behalf of Influence Central for the TB Blood Test. I received a promotional item to thank me for my participation.

When I was pregnant with my daughter, her health was the most important thing to me. It seemed like I was always at the doctors office and having blood drawn constantly. I read every book I could get my hands on that claimed to explain the entire process of pregnancy as well as labor. I know now that none of those books actually prepared me for anything.

I remember my doctor telling me I needed to get a test for tuberculosis and since I was so used to getting poked and prodded I didn’t think anymore of it until the day came when I was scheduled to take the test.

I remember being surprised when instead of a blood draw they gave me a skin test. The person doing the test told me that if I was infected with TB, a raised lump would develop at the site where the tuberculin was injected. I was told I would have to visit the doctor again in a few days to have the site inspected.

The next day when I woke up, I was terrified when a lump appeared and I couldn’t wait to get back to the doctor to have it checked out.

It turned out to be a  false-positive result, which is pretty common with the skin test and I was worried for no reason but I couldn’t help but think that there had to be a better more accurate test.

I have only recently found out that there is a better way to test for TB and that is with the TB Blood Test. It’s the most accurate test for TB infection and it’s only one 3ml draw that can be taken care of in one visit.

I wish I had known about the TB Blood Test then, what has been your experience with getting tested for TB?



  1. I didn’t know there was an actual blood test for TB, as I always get the skin test. Over the years I have probably had 20 TB skin test and all have come back negative. I like the idea of the blood test, especially if I’m already in the lab for a blood draw.

  2. This is the first time I have heard about the blood testing for TB. I think this is way better and safer than the traditional chest x-ray. The skin testing is also not that accurate.

  3. Just so you know, TB tests often swell the next day (and sometimes bruise) and that’s one of the reasons there are pretty strict time frames for reading the test. Positives aren’t false, they just don’t always indicate a current infection. An xray can rule out TB if a skin test is positive.

  4. Working in the nursing dept. at a local college, our students precept in local hospitals and have to have a TB test every year.

  5. I love that they have made a blood test. I have heard about the false positive results from the skin tests before. This is especially important for pregnant women to make sure they get the test done.

  6. Weird, I never had a skin test for TB when I was pregnant and I am pretty sure they did not do a blood test for it then. This is great information to have and know. Good for you for helping to spread the word!

  7. I didn’t even know about this either. In fact I’m pretty sure I wasn’t tested either. I’m very glad to be hearing about this now. At least now I know if I have other kids I’ll be asking my doctor about this.

  8. Wow, I never knew that they did skin tests for TB! I’m not sure, but I must have had the blood test when I was pregnant because I think I would have remembered the skin test. In my opinion, blood tests are always more accurate.

  9. I remember getting a TB test way back when…and I remember having to wait until something appeared on the skin as an indicator. Nothing did, which was a good sign. I did not know that people take the test in regards to pregnancy. However, later in life, I was at the hospital and they accidently put someone in with me who had tuberculosis. I remember them disinfecting everything and doing quarantine-like stuff once they rushed her out of the room.

  10. I’ve had the false positive TB test lump before….and it’s super scary. They don’t tell you that it’s pretty common. So, I panicked thinking I had TB for a whole day until the doctor could see me. 10 TB tests later, I don’t get upset anymore. But like you said, surely there’s a better way. I’m glad to learn that there’s a blood test now. It’ll save everyone from the “false positive freak out.”

  11. * Thanks a lot and keep sharing the information. Keep updating the information for all of us.
