Does Weed Show Up in a TB Blood Test?
A tuberculosis (TB) blood test, also known as an interferon-gamma release assay (IGRA), is a type of blood test that is used to diagnose TB infection. The test measures the body’s immune response to TB bacteria. When someone is infected with TB, their immune system will produce certain proteins called interferons. The IGRA test detects these interferons in the blood.
While the IGRA test is very accurate for diagnosing TB infection, it is not able to distinguish between active TB disease and latent TB infection. Latent TB infection is a condition in which a person has been infected with TB but does not have any symptoms of the disease. People with latent TB infection are not contagious and cannot spread the disease to others. However, they are at an increased risk of developing active TB disease in the future.
Can Weed Affect a TB Blood Test?
There is no evidence that weed affects the accuracy of a TB blood test. However, it is important to note that weed can cause certain side effects, such as increased heart rate and blood pressure. These side effects could potentially interfere with the accuracy of the test, so it is best to avoid consuming weed for at least 24 hours before having a TB blood test.
Does Weed Show Up on a TB Blood Test?
No, weed does not show up on a TB blood test. The IGRA test is specifically designed to detect interferons produced in response to TB bacteria. Weed does not produce these interferons, so it will not show up on the test.
However, it is important to note that a positive TB blood test does not necessarily mean that you have active TB disease. You may have latent TB infection, which is a condition in which you have been infected with TB but do not have any symptoms of the disease. People with latent TB infection are not contagious and cannot spread the disease to others. However, they are at an increased risk of developing active TB disease in the future.
What to Do If You Have a Positive TB Blood Test
If you have a positive TB blood test, your doctor will likely recommend that you have a chest X-ray to rule out active TB disease. If the chest X-ray is normal, you will likely be diagnosed with latent TB infection. Your doctor will then prescribe a course of antibiotics to treat the infection.
If you are diagnosed with active TB disease, you will need to take antibiotics for several months. Treatment for active TB disease is long and complex, but it is important to complete the full course of treatment to prevent the disease from spreading to others.
Conclusion
Weed does not show up on a TB blood test. However, it is important to avoid consuming weed for at least 24 hours before having a TB blood test, as the side effects of weed could potentially interfere with the accuracy of the test.
If you have a positive TB blood test, your doctor will likely recommend that you have a chest X-ray to rule out active TB disease. If the chest X-ray is normal, you will likely be diagnosed with latent TB infection. Your doctor will then prescribe a course of antibiotics to treat the infection.
