New enrolls test sees TB diseases within hours

2004 Gabrielle Benenson This patient is in the process of having her Mantoux tuberculin skin test marked with a pen, thereby, enabling the technician to take an accurate measurement of the reaction site’s area of induration.

The Mantoux tuberculin skin test is used to evaluate people for latent tuberculosis (TB) infection. After the skin test is administered as an intradermal injection, the patient should return in 48 to 72 hours to have the reaction measured and interpreted by a health care provider. To locate the skin test site, the arm should be inspected in good light, and on a firm surface. A light, gentle motion is used to sweep the fingertips over the surface of the forearm to locate the margins or edges of induration.

A millimeter ruler is then used to measure the diameter of the induration between the two marks.

New Delhi, April 5, 2017: US experts said they have satisfactorily built up a blood test that can quickly analyze and quantitate the genuineness of component tuberculosis (TB) cases, a crucial progress against the significant general thriving peril, a media report said.
