QuantiFERON-TB Gold is a simple blood test that accurately identifies people infected with Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). QFT is a modern alternative to the 100-year-old tuberculin skin test (TST or Mantoux).
TB infection (also referred to as latent TB) occurs when a person has the bacteria that cause TB in his or her body, but the bacteria are not causing any disease or symptoms. For those diagnosed with TB infection, there is a chance that the TB bacteria may cause infectious TB disease in the future. The patient is likely to be offered treatment to prevent progression to TB disease. This in turn can prevent the spread of TB to others.
TB and Infertility
Around 30% of the world population (1.7 billion people) is estimated to harbour M. tuberculosis infection. In patients with pulmonary tuberculosis 8-15% with also have urogenital tuberculosis. It affects more men than women (2:1) at a mean age of around 40 years and has an insidious onset,
with urinary symptoms developing in more-advanced disease.
The genitourinary tract is the most common site, after the lungs, for tuberculous infection. Most women with genital tuberculosis present with infertility and pregnancy is unusual, and unlikely, in the presence of genital tuberculosis. When pregnancy occurs, spontaneous abortion, or ectopic pregnancy, often occur.
Endometrial TB is often not considered or misdiagnosed in infertile women particularly in women with infertility of unknown cause. The exact incidence of infertility in patients with genital tuberculosis is not known, but in parts of the world where tuberculosis is common, genital tuberculosis is an important cause of infertility. Women with TB endometritis will also have infection of the fallopian tubes, with irreversible damage to the tubes (TB Salpingitis). Treatment options are IVF.
TB in Female Patients – can affect any part of the genital tract but more commonly involves the fallopian tubes, tuberculous endometritis / salpingitis.
TB in Male Patients – tuberculous epididymo-orchitis/azoospermia
