A positive tuberculosis t-cell spot test usually indicates the presence of tuberculosis infection, but it does not confirm the diagnosis of active tuberculosis.
The T-cell spot test, also known as the T-Spot test, uses Mycobacterium tuberculosis as an antigen to stimulate the release of gamma-interferon from the body’s T-lymphocytes, and determines whether or not the body is infected with Mycobacterium tuberculosis based on the amount of gamma-interferon it produces. A positive result only means that there has been a previous infection with M. tuberculosis, but it does not clarify whether M. tuberculosis is currently present in the body, and the chance of developing the disease at a later stage is about 10%.
If a patient has a positive T-cell spot test for tuberculosis, it is recommended that he or she seek immediate medical attention, cooperate with the doctor to improve the relevant, further clarify the diagnosis, and actively treat the disease, do not delay the condition, so as not to cause adverse consequences.
