A diagnostic test for tuberculosis
Tine test[edit]
The Tine test is a diagnostic tool used to detect tuberculosis (TB) infection. It is a type of tuberculin skin test that involves the use of a small, multi-pronged device to introduce tuberculin into the skin. The test is named after the "tines" or prongs that are used to puncture the skin.
Procedure[edit]
The Tine test is performed by pressing the prongs of the device, which are coated with tuberculin, into the skin, usually on the forearm. The test is considered positive if a certain level of induration (swelling) occurs at the site of application within 48 to 72 hours. The size of the induration is measured to determine the result.
Interpretation[edit]
A positive Tine test indicates that the person has been exposed to the Mycobacterium tuberculosis bacteria and may have a latent or active TB infection. However, the Tine test is less precise than the Mantoux test, which uses a single intradermal injection of tuberculin and is more commonly used in clinical practice.
Limitations[edit]
The Tine test is not as widely used today due to its lower sensitivity and specificity compared to the Mantoux test. It can produce false-positive results in individuals who have been vaccinated with the BCG vaccine or have been exposed to non-tuberculous mycobacteria. False-negative results can occur in individuals with weakened immune systems.
History[edit]
The Tine test was developed as a simpler alternative to the Mantoux test, requiring less training to administer. It was once popular for mass screening programs, especially in schools, due to its ease of use.
