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.
Have I ever told you about the time I had to have a chest x ray because of a TB skin test? No? Okay, here goes… when I was working in the nursing home setting, it was common practice for nurses to have to have an annual TB skin test. The time came for our annual skin tests at work. Like everyone else, I got my skin test at the start of the shift, pushed up my sleeves, and went to work. Then it happened. The injection site actually became red and swollen. Say, WHAT? Like the dutiful nurse I am, I took myself and my swollen skin test site to see the director of nursing. After looking at my arm and debating “is it positive, is it not?” she sent me for a chest x ray, “just to be safe.” As it turns out, I don’t have TB. I had a false positive test, likely caused by scratching the site when it itched after wearing my cuffed sleeves pushed over it for the rest of the shift.
Here’s what I know. Had the TB blood test been available back then, I could have saved myself a lot of worry and a trip to the radiology department! The blood test can help diagnose tuberculosis (TB) infection and is a major scientific advance over the skin test they’ve been using for 110 years! The TB blood test is more accurate, more reliable, and is the the only available method of testing for TB with completely objective results. In other words, it’s not left up to visual interpretation, like the skin test is.
The TB skin test requires two visits, first to get the test and then t hen to read it. The results are subjective and false positives happen. A positive result would be a raised (often red) lump at the site of the injection. The thing is, you can develop severe itching at the puncture site that can lead to a false positive (this from personal experience), as can previous TB vaccination.
By using the TB blood test, you get more accurate results in just one visit. There’s no cross reaction with a previous TB vaccination and it only requires a 3ml draw of fresh blood- regardless of patient age or immune status. Oh, and did I mention fewer unnecessary chest x-rays, which saves time and money?
As a clinician, I would much prefer to use the TB blood test over the more subjective TB skin test. As a patient, if I ever have to be tested again, I know which one I’m choosing!
