Getting a Tuberculosis Skin Test? Here is What to Expect

A tuberculosis skin test in Vancouver allows doctors to determine if the patient is positive for TB. At first, the procedure might be a bit intimidating but once you know more about it and what to expect, you won’t feel as intimidated by it. 
 The procedure itself is quite simple. Basically, you will be going through two parts of it. The first part of the tuberculosis skin test in Vancouver involves injecting a solution. This solution contains tuberculin, which is a protein derivative of Mycobacterium tuberculosis. If the patient is positive for TB, there will be a reaction.

Usually, the doctor will inject it on the forearm. It’s not painless but it’s not very uncomfortable. You can expect to experience some discomfort. On the injection site, you might also see a small bump, also known as the wheal.

The next part of the skin test is the observation stage. This happens 48 to 72 hours after getting the injection. Your doctor will observe the wheal. They will check the size of the wheal. If it is smaller than 4 mm, it usually means a negative result. If the size is larger than 5 mm, it usually means a positive result.

It’s important to talk to your doctor about it first. There are also instances of false positives, likely due to having vaccinations against TB in the past. Your doctor from TravelVax Clinic can explain more about it. In this case, they will go through other tests to ensure the accuracy of your diagnosis.
