7 (p4)) Purple cap: Mitogen that serves as a positive control (non-specific stimulator of T cells), ie to verify that the patient is not immunosuppressed and that the sample has been incubated correctly.

What is the lymphocyte stimulation test for Mitogen?

In the laboratory, the quantity of gamma interferon released by T lymphocytes already sensitized by the infection in the organism is measured after they are put together with specific antigens of certain diseases.

What to do in case of latent tuberculosis?

There are multiple options for the treatment of latent infection, the most common option being treatment with isoniazid (INH) for a shorter or longer period. During isoniazid prophylaxis, most people can continue to work, go to school and have normal activities.
