hi and pleased to answer you The tuberculosis (TB) blood test, also called an Interferon Gamma Release Assay or IGRA, is a way to find out if you have TB germs in your body. for the world health organization, testing for active TB disease through antibodies or antigens found in the blood is extremely difficult. Patients can have different antibody responses suggesting that they have active TB even when they do not. Antibodies may also develop against other organisms which again could wrongly indicate they have active TB. In addition, different organisms share the same antigens, making tests results unreliable. These factors can result in TB disease not being identified or wrongly diagnosed. A blood test for diagnosing active TB disease is bad practice In the best interests of patients and caregivers in the private and public health sectors, WHO is calling for an end to the use of these serological tests to diagnose tuberculosis, said Dr Mario Raviglione, Director of WHO Stop TB Department. A blood test for diagnosing active TB disease is bad practice. Test results are inconsistent, imprecise and put patients lives in danger. For that I urge you to do a prostate ultrasound (endorectal ultrasound) in a RADIOLOGIST office, and a total PSA blood test. Chronic prostatitis can be your diseases and can be the reason of your complaints. I would give you as a treatment: CIPRO 500 twice daily for 30 days. For tuberculosis suspected by urologist, I think that tuberculosis when it happen, multiples signs must be found and the most important are Anorexia, asthenia, slimming and sweating at night. best wishes
